What Does LG Mean on Safety Boots? Ladder Grip Explained
LG stands for Ladder Grip. It's an optional additional marking introduced in the 2022 revision of EN ISO 20345, and it certifies that a shoe's outsole has been tested for its ability to hold onto a ladder rung. To be upfront: XNEXZ footwear does not carry the LG marking. Our shoes weren't tested for it, so if regular ladder work is part of your job, you should be looking at footwear we don't make. Details on why are further down. Slip resistance and ladder grip are not the same test, and passing one tells you nothing about the other. A shoe can be excellent on a wet floor and untested on a rung. What the LG Marking Actually Certifies Almost every safety footwear code describes something happening to your foot: an impact on the toe, a nail from below, water from above. LG is different. It describes how the shoe behaves on a narrow horizontal bar. The test focuses on the part of the sole that actually rests on a rung when you climb: the region between the heel and the forepart, underneath the arch. On most shoes this is the section that curves upward and away from the ground, so it never touches a floor at all. It's dead space in every other test, and it's the entire subject of this one. For a shoe to pass, that arch region needs a transverse profile, meaning grooves or bars running across the sole rather than along it, of sufficient depth to seat against a rung and resist sliding. The standard sets a minimum profile height of 1.5mm in that area as the basis for the test. The sole region tested by the LG ladder grip marking A side view of a shoe sole resting on a ladder rung. The contact region sits between the heel and forepart, beneath the arch, which is the area the LG test assesses. Other slip tests measure the heel and forefoot against a flat floor instead. ladder rung LG test region arch, between heel and forepart forepart heel tested by SR tested by SR tested by LG only Slip resistance testing loads the heel and forefoot against a flat floor. The arch region in the middle is only assessed by the LG test. Where the Test Came From LG isn't a newly invented test. It was already part of the standard for firefighters' footwear, where ladder work is a core part of the job and the consequences of a slip are severe. What the 2022 revision did was lift that requirement out of the firefighting specification and make it available as a standalone optional test for all safety footwear. The reasoning is straightforward: firefighters aren't the only people who spend their working lives on rungs. Electricians, telecoms engineers, roofers, scaffolders, HVAC installers, warehouse operatives on stock ladders and maintenance teams all climb regularly, and until 2022 none of them had a certification that spoke to it. Why Slip Resistance Doesn't Cover This This is the part most buyers get wrong, and it's worth being precise about. Slip resistance testing measures a shoe against a flat surface. It loads the heel at the angle of a heel strike, and it loads the forefoot flat, then measures the coefficient of friction. Under the 2022 revision, a baseline version of that test became mandatory for all safety footwear, with an additional glycerol test marked SR. Our guide to non-slip safety shoes covers how those tests work. A ladder rung presents a completely different mechanical problem. The contact area is a narrow bar rather than a plane. The load sits under the arch rather than the heel or forefoot. And the failure mode isn't sliding forward across a floor, it's the foot rolling off the rung sideways or slipping off the front. Friction on a flat tile tells you very little about any of that. A sole compound can be superb on wet ceramic and still have a smooth, featureless arch that sits on a rung like a bar of soap. SR, slip resistance LG, ladder grip Surface tested against Flat ceramic tile Ladder rung Sole region loaded Heel and forefoot Arch, between heel and forepart Failure mode measured Sliding across a floor Slipping off or rolling from a rung Status in the standard Baseline test mandatory, SR is an additional test Optional additional test Relevant to Walking and standing Climbing Who Actually Needs LG Ladder grip matters in proportion to how much of your day happens off the ground. Some rough tiers: Look for LG as a priority. Scaffolders, roofers, telecoms and aerial engineers, window cleaners, tree surgeons, and anyone whose job is fundamentally about working at height. Strongly worth having. Electricians, HVAC and refrigeration engineers, plumbers, painters and decorators working from steps, signage installers, and building maintenance teams. These roles climb daily but not continuously. Useful but not essential. Warehouse operatives using picking ladders, retail stockroom staff, and facilities workers with occasional access ladders. Worth having if the option exists at the same price. Not a factor. Roles that are entirely ground-level: most warehouse picking, delivery driving, indoor fit-out on finished floors, workshop and production line work. If you're in the first tier, LG should be a filter you apply before anything else. If you're in the last, it's a feature you'd be paying for and never using. The Honest Limits of an LG Marking LG is a genuine improvement to the standard, and it's worth saying clearly what it doesn't do. It's a laboratory test, not a guarantee. Passing means the outsole met a defined performance threshold under controlled conditions on a specified rung. Real ladders vary in material, diameter, wear and contamination. Mud, ice, oil and paint on a rung will affect grip in ways no marking accounts for. It says nothing about the rest of your ladder safety. Footwear is the last line, not the first. Correct ladder angle, secure footing, three points of contact, load limits and inspection all matter more than sole geometry. Under the Work at Height Regulations 2005, ladders should be used only where a risk assessment shows more suitable equipment isn't justified, and your employer's duty to plan and supervise that work sits well above any question of footwear. Our overview of the UK PPE at Work Regulations covers where footwear fits into that wider picture. Absence of LG doesn't mean a shoe grips badly on rungs. Because the test is optional, plenty of well-made boots with aggressive transverse tread patterns have never been submitted for it. Untested is not the same as failed. What you lose without the marking is verification, not necessarily performance. It doesn't override site rules. An LG-marked low-cut shoe still won't get you onto a site that requires S3 boots with ankle coverage. How Outsole Design Affects Ladder Grip Understanding what the test looks for helps you judge footwear that hasn't been tested. The feature that matters is a transverse profile in the arch: ridges or bars running across the sole, side to side, which can seat against a rung and stop the foot sliding forward off it. A sole with deep longitudinal grooves running heel to toe may look aggressive and do very little on a rung, because the grooves run parallel to the bar rather than across it. Material matters too, though less than geometry. Softer, higher-friction compounds deform slightly around a rung and grip better, while harder compounds hold their shape and rely more on the profile. This is part of the wider trade-off between outsole materials, which we cover in our comparison of PU and rubber outsoles. A quick sanity check you can do in a shop: turn the shoe over and look at the waist of the sole, the narrow part in the middle. If it's smooth, flat or hollowed out with no cross-pattern at all, it's not designed with rungs in mind, whatever the rest of the tread looks like. Two Worked Examples Scenario 1 Commercial electrician, second fix Twenty to thirty ladder or step ascents a day, running cable at ceiling level. Ground conditions are finished floors, so slip resistance is comfortably handled by any certified shoe. The repeated exposure is all vertical. LG should be a priority filter. This is exactly the profile the marking was extended beyond firefighting to serve. Scenario 2 Warehouse picker with occasional stock ladder use Fifteen thousand steps a day on flat sealed floor, with a handful of climbs up a three-step stock ladder to reach upper racking. Nice to have, not a deciding factor. Weight, cushioning and floor slip resistance will affect this worker far more across a shift than rung geometry. How to Check for LG Read the full marking on the tongue label or insole stamp. LG appears alongside other optional codes such as SR, FO, HRO and WPA, after the base rating. Check the standard version. LG only exists under EN ISO 20345:2022 and later. Footwear certified to the 2011 version cannot carry it, because the test wasn't available for general safety footwear then. Ask the retailer or manufacturer for the certificate if the marking is unclear. The EU type examination certificate lists every tested property explicitly, and a reputable seller will provide it. Don't infer it from marketing language. Phrases like "ladder-friendly sole" or "climbing grip" carry no certification weight. Only the LG marking on the certificate means the test was passed. Check it against your employer's requirement. If your risk assessment specifies LG, footwear without it doesn't meet the requirement however good the tread looks. Where XNEXZ Stands, Honestly PulseX and StrideX are certified S1PL FO SR under EN ISO 20345:2022+A1:2024. That covers S1 base protection, a non-metallic puncture-resistant insert tested with the 4.5mm nail, a fuel-and-oil-resistant outsole, and the additional slip resistance test. LG is not on the certificate. The ladder grip test was not carried out, so we make no ladder grip claim of any kind. We designed for a different problem. Our shoes are built for people who spend long shifts walking on flat, sealed indoor floors, where weight and cushioning across ten thousand steps matter more than rung geometry. That's warehousing, delivery, facilities, workshops and indoor trade work. If ladders are a routine part of your day, buy footwear that carries LG on its certificate. If they aren't, and you want to know what our rating does cover, that's set out in our complete UK guide to S1P safety shoes. Suitable For / Choose Differently LG is worth prioritising if you are A scaffolder, roofer or steeplejack A telecoms, aerial or satellite engineer An electrician working at ceiling level daily An HVAC, refrigeration or plumbing engineer A window cleaner or facade worker A signage or lighting installer In any role where climbing is a core daily task LG is unlikely to matter if you are A warehouse picker on ground-level racking A delivery driver or depot worker An indoor fit-out or finishing trade on flat floors A production line or workshop operative Retail stockroom staff with rare ladder use Security or facilities staff on ground level The Honest Verdict LG fills a real gap. Before 2022, a worker who spent half their day on rungs had no certification that measured the thing most likely to hurt them, and slip resistance testing was routinely mistaken for covering it. It doesn't. If you climb regularly, treat LG as a filter rather than a bonus feature, and don't accept marketing language in its place. If you don't climb, it's a code you can safely ignore, and there are other properties on the label that will affect your working day far more. Not Working at Height? We'd Like Your Feedback If your work is ground-level, warehouse, delivery, facilities or indoor trade, and your employer accepts S1P footwear, try PulseX or StrideX and tell us honestly how they hold up over a full shift. If ladders are part of your daily routine, buy LG-marked footwear from a brand that has done that test. We haven't.

It's an optional marking under EN ISO 20345:2022 confirming the outsole passed a test for gripping ladder rungs, focused on the arch area between the heel and forepart. Is LG the same as slip resistance? No. Slip resistance tests the heel and forefoot against a flat floor. LG tests the arch region against a narrow rung. They measure different sole areas against different surfaces, and passing one says nothing about the other. Is the LG test mandatory? No, it's an optional additional test. Manufacturers choose whether to submit footwear for it, which is why many well-made boots have no LG marking despite having suitable tread. Where did the ladder grip test come from? It was already part of the standard for firefighters' footwear. The 2022 revision made it available as a standalone optional test for all safety footwear, since firefighters are not the only workers who climb regularly. Can older safety boots have an LG marking? No. LG only exists under EN ISO 20345:2022 and later. Footwear certified to the 2011 version cannot carry it, because the test wasn't available for general safety footwear at that time. Does LG mean my footwear is safe on any ladder? No. It means the outsole passed a controlled laboratory test on a specified rung. Real rungs vary in material, wear and contamination, and mud, ice or oil will affect grip regardless of the marking. Safe ladder use depends far more on setup, angle and three points of contact than on footwear. Do XNEXZ shoes have the LG marking? No. PulseX and StrideX are certified S1PL FO SR, and the ladder grip test was not carried out. If ladder work is routine for you, look for footwear that carries LG on its certificate.

Can You Wear Trainers on a UK Building Site?
This question gets asked in two very different ways, and they have two very different answers. Someone asking whether they can wear their everyday Nikes on site is asking one thing. Someone asking whether their certified S1P safety trainers will get them through the gate is asking something else entirely. Worth saying upfront: XNEXZ makes safety trainers, and our own shoes are not suitable for building sites. We'll explain exactly why further down. If you've landed here looking for footwear for construction work, the honest answer is that you need something we don't make. Ordinary trainers are banned on every UK construction site, without exception. Certified safety trainers are a site-by-site decision, and most major contractors say no to low-cut footwear regardless of its rating. Ordinary Trainers: A Straightforward No Regular trainers, running shoes, skate shoes, anything without an EN ISO 20345 certification, are not permitted on UK construction sites. There's no grey area here and no site that quietly allows it. The reason is simple. A construction site has dropped materials, rolling loads, sharp debris underfoot, and uneven ground. An uncertified trainer has no toe cap, no puncture-resistant midsole, and no tested slip resistance. It offers no protection against any of the hazards that footwear on a site is there to address. You will be stopped at induction, and if you're spotted on site in them you'll be removed until you change. Some sites operate a strike system that can affect your future access. This isn't a technicality being enforced pedantically, it's the first thing a gate check looks at. What UK Law Actually Says Here's the part that surprises people: no UK regulation names S3, or any other EN ISO rating, as a legal minimum for construction. The law is written in terms of suitability, not product codes. The PPE at Work Regulations The Personal Protective Equipment at Work Regulations 1992, as amended in 2022, place a duty on the employer to assess the risks in the work and provide PPE that is suitable for those risks. Suitable means appropriate to the hazard, correctly fitted, and compatible with any other PPE being worn. Two practical points that workers often don't know. First, the 2022 amendment extended these duties to cover a wider group of workers, including many casual and agency arrangements that previously sat outside the regulations. Second, your employer must provide required PPE free of charge. If you're being told to buy your own site boots out of your own pocket, that's worth questioning. Our guide to the UK PPE at Work Regulations covers what employers owe you in more detail. The CDM Regulations The Construction (Design and Management) Regulations 2015 place duties on the principal contractor to prepare and enforce site rules. This is where the specific footwear requirement comes from. The law says "suitable," the contractor translates that into "S3 safety boots, no exceptions," and writes it into the site rules you agree to at induction. That translation is why the answer to this question varies between sites while the underlying law does not. What Site Rules Typically Require In practice, most UK construction sites specify some version of the following, though you must check your specific site rather than relying on any general pattern: S3 rating as a minimum. S3 combines a water-resistant upper, a puncture-resistant midsole and a cleated outsole. The reasoning is that sites are wet, sharp and uneven, and S3 addresses all three. Our comparison of S1P and S3 safety shoes explains what separates them. Ankle coverage. Many contractors require footwear that covers the ankle, stated as a separate requirement from the rating. This is the clause that excludes low-cut shoes even when they're properly certified. Visible, legible certification marking. If the tongue label has worn away and you can't demonstrate the rating, some sites will treat the footwear as uncertified. Condition requirements. Worn soles, exposed toe caps or split uppers can fail a check even on correctly rated boots. Larger principal contractors on major projects tend to be stricter and more consistent. Smaller domestic sites and refurbishment work vary considerably, which is where most of the confusion comes from. Will Your Footwear Get Through the Gate? Work down this flow before you buy anything, not on the morning of your induction. Decision flow for whether footwear is accepted on a UK construction site First, footwear must be certified to EN ISO 20345 or it is refused. Second, it must meet the site's required rating, usually S3. Third, if site rules require ankle coverage, low-cut footwear is refused and boots are needed. Otherwise, confirm acceptance at induction. Certified to EN ISO 20345? Check the tongue label or insole stamp Refused every UK site No Meets the site's required rating? Usually S3 on construction Refused rating too low No Do site rules require ankle cover? Stated separately from the rating Boots required low cut refused Yes Low cut may be accepted Confirm in writing at induction before buying No Site rules vary. This flow is a guide, your induction is the authority. Certification, rating and ankle coverage are three separate hurdles. Footwear has to clear all three. Footwear Types and Realistic Site Acceptance General patterns only, always confirm against your specific site rules Footwear Typical construction site outcome Why Ordinary trainers Refused No certification, no toe cap, no tested protection of any kind S1 safety trainers Refused No puncture resistance and no water resistance, well below site requirements S1P safety trainers Usually refused Has puncture resistance but no water-resistant upper, and rating sits below S3 S3 low-cut safety shoes Sometimes accepted Meets the rating, but fails any separate ankle coverage requirement S3 safety boots Generally accepted Meets both the rating and the ankle coverage clause on most sites For the full picture of what each code covers, see our breakdown of safety shoe ratings from SB to S7. Why Sites Insist on Boots Rather Than Rated Trainers If an S3 low-cut shoe meets the rating, why do so many sites still require boots? Four reasons, and they're all reasonable. Ground conditions. Trench edges, loose spoil, scaffold boards and rubble are exactly the surfaces where restricting ankle roll matters. A rating measures the shoe, not the terrain. Debris ingress. An open collar lets aggregate, hot swarf, sparks and standing water into the shoe. On a site, that's a daily occurrence rather than an edge case. Enforcement simplicity. "Boots above the ankle" is checkable from ten feet away at a gate. "S3 or above" requires reading a worn label on every pair. Site safety rules are written to be enforced quickly by people who aren't footwear specialists. Insurance and client requirements. Principal contractors often inherit footwear clauses from client contracts or insurers. The site manager frequently has no discretion to vary them even if they wanted to. Where Safety Trainers Are Genuinely Accepted Safety trainers do have legitimate places in and around the construction sector. They're simply not on the active build. Second-fix and interior finishing. Once a building is watertight and the floors are clean and level, some sites relax requirements for finishing trades. This varies enormously and must be confirmed, not assumed. Site offices and welfare compounds. Where a rating is still required but conditions are indoor. Builders merchants, yards and trade counters. Certified footwear needed, but usually not to site-boot specification. Off-site fabrication and joinery workshops. Flat sealed floors, controlled environments. Estimating, surveying and supervisory roles. Though anyone actually walking the works still needs full site footwear. Outside construction entirely, safety trainers are the mainstream choice for warehousing, delivery, facilities and indoor trade work, which is the territory covered in our guide to work safety shoes for light-duty roles. Two Worked Examples Scenario 1 Electrician starting on a new-build housing site First fix, timber frame stage. The ground is unmade, there are off-cuts and fixings everywhere, and it rains. The induction pack specifies S3 boots with ankle protection. S3 boots, no discretion. Safety trainers of any rating will be refused at the gate. Scenario 2 Decorator on a commercial fit-out, building already watertight Sealed floors, no exposed ground, no standing water. The main contractor's rules for the finishing phase specify certified safety footwear without naming a format. Safety trainers may be acceptable, but get it confirmed by the site manager in writing before the first day rather than turning up and hoping. How to Check Before You Buy Ask for the site's PPE requirement in writing before you spend anything. The induction pack, site rules document or your agency should have it. Check whether it names a rating, a format, or both. "S3" and "boots covering the ankle" are two separate requirements, and plenty of sites specify both. Ask who pays. Employers are required to provide necessary PPE free of charge. If you're an agency worker, ask the agency directly rather than assuming you're on your own. Confirm any relaxation with a named person. If someone tells you trainers are fine for your phase of work, get it from the site manager and get it in writing. Verbal permission from a colleague will not help you at the gate. Check the condition of what you already own. Worn tread, a visible toe cap or an illegible marking can fail a check on otherwise correct boots. Where XNEXZ Stands, Honestly XNEXZ makes two low-cut safety trainers, PulseX and StrideX, certified S1PL FO SR under EN ISO 20345:2022+A1:2024. That is S1 base protection, a non-metallic puncture-resistant insert, a fuel-and-oil-resistant outsole and slip resistance. They fail the typical construction requirement on two counts, not one. The rating is S1P rather than S3, so there is no water-resistant upper on the certificate. And they are low cut, so they fail any ankle coverage clause regardless of rating. Do not buy XNEXZ for building site work. You would be turned away, and we would rather lose the sale than have that happen to you. What we build for is different work entirely: warehouses, indoor fit-out, delivery, facilities and workshop roles on flat sealed floors. If that describes your job, the detail on what our rating covers is in our complete UK guide to S1P safety shoes. If you're heading onto a live site, buy S3 boots from a brand that makes them properly. Suitable For / Choose Differently Safety trainers may be accepted for Warehouse and distribution work Indoor fit-out once the building is watertight, if confirmed Off-site workshops and fabrication units Builders merchants and trade counters Delivery, courier and depot roles Facilities and light maintenance You need S3 boots for Any live construction site, new build or refurbishment Groundworks, demolition and civils Roofing, scaffolding and work at height First fix on an unfinished building Any site whose rules name S3 or ankle coverage Anywhere you cannot get a written relaxation The Honest Verdict Ordinary trainers on a UK building site: never. Certified safety trainers: possible on some finishing-phase and off-site work, but genuinely uncommon on a live site, and you should treat any assumption otherwise as wrong until a site manager tells you differently in writing. The requirement that catches most people out isn't the rating, it's the separate ankle coverage clause. You can buy a properly certified S3 low-cut shoe and still be refused entry, because the site rules ask for two things and the label only answers one of them. Not On Site? Then We'd Like Your Feedback If your work is warehouse, delivery, indoor trade or facilities, and your employer accepts S1P footwear, try PulseX or StrideX and tell us honestly how they hold up over a real shift. If you're on a live construction site, please buy S3 boots instead. That's the right call and we're not going to pretend otherwise. View PulseX View StrideX Frequently Asked Questions Can I wear normal trainers on a building site? No. Uncertified footwear is not permitted on any UK construction site. You'll be stopped at induction or removed from site until you change into certified safety footwear. Are S1P safety trainers allowed on construction sites? Usually not. Most sites specify S3 as a minimum, and S1P has no water-resistant upper. Many sites also require ankle coverage as a separate condition, which low-cut trainers cannot meet regardless of rating. Does UK law say I must wear S3 boots on site? No regulation names a specific rating. The PPE at Work Regulations require footwear suitable for the assessed risk, and the CDM Regulations require the principal contractor to set site rules. The S3 requirement comes from those site rules, not directly from statute. Who pays for my safety boots? Where PPE is necessary for the work, the employer must provide it free of charge under the PPE at Work Regulations. If you're being asked to fund required site boots yourself, raise it with your employer or agency. Are low-cut S3 safety shoes accepted on site? Sometimes, but often not. They meet the rating requirement while failing any separate ankle coverage clause. Check whether your site rules specify a format as well as a rating before buying. What happens if I turn up in the wrong footwear? You'll typically be refused entry at induction or sent off site to change, losing the day's work. Some contractors record it against your site access record, which can affect future work with them. Can I wear safety trainers for interior fit-out work? Possibly, once the building is watertight and the floors are finished, but this depends entirely on the principal contractor's rules for that phase.

Can You Wear Trainers on a UK Building Site?
This question gets asked in two very different ways, and they have two very different answers. Someone asking whether they can wear their everyday Nikes on site is asking one thing. Someone asking whether their certified S1P safety trainers will get them through the gate is asking something else entirely. Worth saying upfront: XNEXZ makes safety trainers, and our own shoes are not suitable for building sites. We'll explain exactly why further down. If you've landed here looking for footwear for construction work, the honest answer is that you need something we don't make. Ordinary trainers are banned on every UK construction site, without exception. Certified safety trainers are a site-by-site decision, and most major contractors say no to low-cut footwear regardless of its rating. Ordinary Trainers: A Straightforward No Regular trainers, running shoes, skate shoes, anything without an EN ISO 20345 certification, are not permitted on UK construction sites. There's no grey area here and no site that quietly allows it. The reason is simple. A construction site has dropped materials, rolling loads, sharp debris underfoot, and uneven ground. An uncertified trainer has no toe cap, no puncture-resistant midsole, and no tested slip resistance. It offers no protection against any of the hazards that footwear on a site is there to address. You will be stopped at induction, and if you're spotted on site in them you'll be removed until you change. Some sites operate a strike system that can affect your future access. This isn't a technicality being enforced pedantically, it's the first thing a gate check looks at. What UK Law Actually Says Here's the part that surprises people: no UK regulation names S3, or any other EN ISO rating, as a legal minimum for construction. The law is written in terms of suitability, not product codes. The PPE at Work Regulations The Personal Protective Equipment at Work Regulations 1992, as amended in 2022, place a duty on the employer to assess the risks in the work and provide PPE that is suitable for those risks. Suitable means appropriate to the hazard, correctly fitted, and compatible with any other PPE being worn. Two practical points that workers often don't know. First, the 2022 amendment extended these duties to cover a wider group of workers, including many casual and agency arrangements that previously sat outside the regulations. Second, your employer must provide required PPE free of charge. If you're being told to buy your own site boots out of your own pocket, that's worth questioning. Our guide to the UK PPE at Work Regulations covers what employers owe you in more detail. The CDM Regulations The Construction (Design and Management) Regulations 2015 place duties on the principal contractor to prepare and enforce site rules. This is where the specific footwear requirement comes from. The law says "suitable," the contractor translates that into "S3 safety boots, no exceptions," and writes it into the site rules you agree to at induction. That translation is why the answer to this question varies between sites while the underlying law does not. What Site Rules Typically Require In practice, most UK construction sites specify some version of the following, though you must check your specific site rather than relying on any general pattern: S3 rating as a minimum. S3 combines a water-resistant upper, a puncture-resistant midsole and a cleated outsole. The reasoning is that sites are wet, sharp and uneven, and S3 addresses all three. Our comparison of S1P and S3 safety shoes explains what separates them. Ankle coverage. Many contractors require footwear that covers the ankle, stated as a separate requirement from the rating. This is the clause that excludes low-cut shoes even when they're properly certified. Visible, legible certification marking. If the tongue label has worn away and you can't demonstrate the rating, some sites will treat the footwear as uncertified. Condition requirements. Worn soles, exposed toe caps or split uppers can fail a check even on correctly rated boots. Larger principal contractors on major projects tend to be stricter and more consistent. Smaller domestic sites and refurbishment work vary considerably, which is where most of the confusion comes from. Will Your Footwear Get Through the Gate? Work down this flow before you buy anything, not on the morning of your induction. Decision flow for whether footwear is accepted on a UK construction site First, footwear must be certified to EN ISO 20345 or it is refused. Second, it must meet the site's required rating, usually S3. Third, if site rules require ankle coverage, low-cut footwear is refused and boots are needed. Otherwise, confirm acceptance at induction. Certified to EN ISO 20345? Check the tongue label or insole stamp Refused every UK site No Meets the site's required rating? Usually S3 on construction Refused rating too low No Do site rules require ankle cover? Stated separately from the rating Boots required low cut refused Yes Low cut may be accepted Confirm in writing at induction before buying No Site rules vary. This flow is a guide, your induction is the authority. Certification, rating and ankle coverage are three separate hurdles. Footwear has to clear all three. Footwear Types and Realistic Site Acceptance General patterns only, always confirm against your specific site rules Footwear Typical construction site outcome Why Ordinary trainers Refused No certification, no toe cap, no tested protection of any kind S1 safety trainers Refused No puncture resistance and no water resistance, well below site requirements S1P safety trainers Usually refused Has puncture resistance but no water-resistant upper, and rating sits below S3 S3 low-cut safety shoes Sometimes accepted Meets the rating, but fails any separate ankle coverage requirement S3 safety boots Generally accepted Meets both the rating and the ankle coverage clause on most sites For the full picture of what each code covers, see our breakdown of safety shoe ratings from SB to S7. Why Sites Insist on Boots Rather Than Rated Trainers If an S3 low-cut shoe meets the rating, why do so many sites still require boots? Four reasons, and they're all reasonable. Ground conditions. Trench edges, loose spoil, scaffold boards and rubble are exactly the surfaces where restricting ankle roll matters. A rating measures the shoe, not the terrain. Debris ingress. An open collar lets aggregate, hot swarf, sparks and standing water into the shoe. On a site, that's a daily occurrence rather than an edge case. Enforcement simplicity. "Boots above the ankle" is checkable from ten feet away at a gate. "S3 or above" requires reading a worn label on every pair. Site safety rules are written to be enforced quickly by people who aren't footwear specialists. Insurance and client requirements. Principal contractors often inherit footwear clauses from client contracts or insurers. The site manager frequently has no discretion to vary them even if they wanted to. Where Safety Trainers Are Genuinely Accepted Safety trainers do have legitimate places in and around the construction sector. They're simply not on the active build. Second-fix and interior finishing. Once a building is watertight and the floors are clean and level, some sites relax requirements for finishing trades. This varies enormously and must be confirmed, not assumed. Site offices and welfare compounds. Where a rating is still required but conditions are indoor. Builders merchants, yards and trade counters. Certified footwear needed, but usually not to site-boot specification. Off-site fabrication and joinery workshops. Flat sealed floors, controlled environments. Estimating, surveying and supervisory roles. Though anyone actually walking the works still needs full site footwear. Outside construction entirely, safety trainers are the mainstream choice for warehousing, delivery, facilities and indoor trade work, which is the territory covered in our guide to work safety shoes for light-duty roles. Two Worked Examples Scenario 1 Electrician starting on a new-build housing site First fix, timber frame stage. The ground is unmade, there are off-cuts and fixings everywhere, and it rains. The induction pack specifies S3 boots with ankle protection. S3 boots, no discretion. Safety trainers of any rating will be refused at the gate. Scenario 2 Decorator on a commercial fit-out, building already watertight Sealed floors, no exposed ground, no standing water. The main contractor's rules for the finishing phase specify certified safety footwear without naming a format. Safety trainers may be acceptable, but get it confirmed by the site manager in writing before the first day rather than turning up and hoping. How to Check Before You Buy Ask for the site's PPE requirement in writing before you spend anything. The induction pack, site rules document or your agency should have it. Check whether it names a rating, a format, or both. "S3" and "boots covering the ankle" are two separate requirements, and plenty of sites specify both. Ask who pays. Employers are required to provide necessary PPE free of charge. If you're an agency worker, ask the agency directly rather than assuming you're on your own. Confirm any relaxation with a named person. If someone tells you trainers are fine for your phase of work, get it from the site manager and get it in writing. Verbal permission from a colleague will not help you at the gate. Check the condition of what you already own. Worn tread, a visible toe cap or an illegible marking can fail a check on otherwise correct boots.

Safety Trainers vs Boots: Which Should You Actually Buy?
Before anything else, a disclosure that should shape how you read this: XNEXZ makes safety trainers, not safety boots. We have a commercial interest in one side of this comparison. So we've tried to make the case for boots as strongly as anyone selling them would, and we'll point you away from our own products wherever boots are the better answer. The good news is that the honest version of this comparison isn't especially close in either direction. For a large share of UK jobs, the right answer is obvious once you know what actually separates the two formats. Three things decide it: how much ankle coverage your ground demands, how much weight your legs carry over a shift, and which safety rating your site requires. Style comes fourth, and it only matters after the first three agree. The Four Real Differences Strip away the marketing and the two formats differ in four measurable ways. 1. Ankle coverage This is the defining difference. A safety trainer is a low-cut shoe that finishes below the ankle bone. A safety boot rises above it, typically to mid-ankle or higher, wrapping the joint in structured material. That extra height does three separate jobs, and they're worth separating because they're often lumped together. It restricts how far the ankle can roll on uneven ground. It physically blocks debris, sparks, splashes and grit from dropping into the shoe. And it adds a layer of impact protection over the ankle bone itself. 2. Weight Boots are heavier, and the gap is meaningful. A typical safety trainer often falls somewhere in the region of 400 to 600 grams per shoe, while boots more commonly sit between 600 and 900 grams, though both ranges vary widely by model, sole material and toe cap type. Check the stated weight of the specific model rather than assuming. Weight on the foot costs more energy than weight carried anywhere else on the body, because you lift and accelerate it with every step. Over ten thousand steps that difference compounds, which is the subject of our piece on the hidden cost of heavy safety shoes. 3. Available safety ratings This is the difference most buyers miss, and it's often the one that settles the argument. Higher ratings correlate strongly with the boot format for practical reasons: S3 and above are built for wet, rough outdoor ground, and manufacturers build those specifications into boots because that's where the demand sits. Metatarsal protection and ankle protection codes are also almost exclusively boot territory. Trainers dominate the S1 and S1P end of the range instead. If your site specifies S3, your realistic options are mostly boots. If it specifies S1P, you have both formats to choose from. Our comparison of S1P and S3 safety shoes covers which rating suits which environment. 4. Debris and ingress An open collar is an opening. On a site with loose aggregate, hot swarf, sparks or standing water, a low-cut trainer lets material in over the collar in a way a boot simply doesn't. On a clean warehouse floor, that opening is irrelevant. Side by Side Safety trainers Safety boots Ankle coverage Below the ankle bone Mid-ankle or higher Typical weight per shoe Around 400 to 600g Around 600 to 900g Common ratings S1, S1P, occasionally S2 S3, S5, S7, plus S1P options Debris protection at the collar Limited Strong Break-in period Usually short Often longer, especially in leather Breathability Generally better, mesh uppers common Generally lower, more enclosed On and off speed Fast Slower, more lace height Off-site appearance Passes as ordinary footwear Visibly workwear Ankle coverage compared across low-cut trainers, mid-cut and high-cut boots A low-cut safety trainer finishes below the ankle bone. A mid-cut boot covers the ankle joint. A high-cut boot extends above it toward the lower shin. Low cut Trainer ankle exposed Mid cut Ankle boot ankle covered High cut Rigger or hiker boot ankle and lower shin ankle bone line The dashed line marks the ankle bone. Everything above it is coverage a trainer does not provide. The Ankle Support Claim, Handled Honestly "Boots support your ankles" is the single most repeated line in safety footwear marketing. It deserves a more careful answer than either side usually gives it. What a boot definitely does is restrict range of motion. A structured collar physically limits how far the joint can roll. On uneven ground, rubble, kerbs, trench edges and scaffolding, that restriction is genuinely useful, and it's why boots are standard on construction sites rather than a marketing preference. What's less settled is whether that restriction meaningfully reduces injury rates on flat, predictable surfaces. Research on high-top versus low-top footwear in sport has produced mixed findings, and some evidence suggests that relying on external support can, over long periods, do less for joint stability than the surrounding muscles do. We're not going to pretend that debate is resolved, and we're certainly not going to resolve it in a blog post written by a company that sells low-cut shoes. The practical takeaway is narrower and more reliable: match the coverage to the ground. Uneven, sloped, cluttered or outdoor ground is a strong argument for a boot regardless of how the wider debate settles. Flat indoor floors are not. When Boots Are Clearly the Right Answer These aren't edge cases. They cover a large share of UK site work, and in every one of them we'd tell you to buy a boot rather than anything we make. Construction, groundworks and demolition. Uneven ground, wet conditions, sharp debris and heavy materials underfoot. Usually S3 as a minimum, which is boot territory anyway. Roofing, scaffolding and civil engineering. Working at height on irregular surfaces, where ankle roll carries far greater consequences. Outdoor work in wet or cold conditions. Boots offer more enclosure and are far more commonly available with water-resistant and waterproof certification. Welding, foundry and hot work. An open collar and sparks are a bad combination. Look for heat-resistant codes and boot coverage. Agriculture, forestry and landscaping. Mud, uneven terrain and heavy machinery all favour full coverage. Anywhere your site policy specifies boots. This overrides every other consideration on this page. When Trainers Are the Better Choice Equally, there's a large category of work where a boot is simply more shoe than the job needs, and the extra weight buys protection against hazards that aren't present. Warehouse and distribution work. Flat sealed floors, long walking distances, and the main hazard being dropped items rather than uneven ground. Indoor trade and fit-out work. Interior joinery, decorating, electrical second-fix and similar, on finished floors. Delivery, courier and depot roles. Frequent in and out of vehicles, high step counts, mostly hard surfaces. Facilities, maintenance and light engineering. Mixed indoor environments where mobility matters more than enclosure. Retail stockrooms and back-of-house. Flat floors, customer-facing appearance sometimes a factor. Roles that cross between work and public settings. Where visibly heavy workwear boots feel out of place. What these have in common is flat, predictable ground and long hours on it. That's the profile where the weight difference starts to matter and the coverage difference stops mattering, a trade-off we look at in more detail in lightweight safety shoes: what you gain. The Middle Ground: Safety Trainer Boots There's a third category worth knowing about. Safety trainer boots, sometimes called hiker-style safety boots, use a trainer's sole unit and construction with a mid-cut ankle collar. They aim to keep some of the lightness and flexibility while adding the collar coverage. They're a genuine compromise rather than a marketing category, and for mixed roles that move between indoor and outdoor work across the week they often make more sense than committing to either extreme. They are, inevitably, heavier than a low-cut trainer and less protective than a full site boot. XNEXZ doesn't currently make one. Two Worked Examples Scenario 1 Warehouse picker, ten-hour shifts, sealed concrete floor Fifteen thousand steps a shift on flat ground. The realistic hazards are dropped stock, box staples and banding wire. Nothing on the floor is uneven, wet or hot. Trainers. The boot's coverage would guard against hazards this role doesn't face, while the extra weight is paid for on every one of those steps. Scenario 2 Groundworker on a residential site through winter Trench edges, loose spoil, standing water, rebar and timber off-cuts underfoot. Ground conditions change through the day and rarely stay flat. Boots, almost certainly S3. This is the case where lightweight trainers are the wrong tool, and no amount of comfort compensates for the missing coverage. What Doesn't Actually Differ A few assumptions are worth clearing up, because they push people toward boots for reasons that don't hold. Toe protection. A 200 joule toe cap is a 200 joule toe cap. A certified trainer and a certified boot meet the identical impact and compression thresholds. Height above the ankle adds nothing to toe protection. Slip resistance. This is a function of the outsole compound and tread pattern, not the height of the collar. A well-designed trainer sole can outperform a poorly designed boot sole. Puncture resistance. Also underfoot, also unrelated to cut height. Both formats can carry P, PL or PS markings. Durability, necessarily. Boots often last longer because they're built heavier, but a well-made trainer can outlast a cheap boot. Construction quality matters more than category. How to Decide Check your site's PPE policy first. If it names a rating or a format, that's your answer and the rest of this list is background reading. Under the PPE at Work Regulations 2022, specifying suitable footwear is your employer's duty, not your judgement call. Describe your ground honestly. Flat and sealed, or uneven, sloped, wet, or covered in loose material? Be honest about the worst day, not the average one. Count your hours and your steps. Over eight hours of walking, weight compounds. Over four hours mostly stationary, it barely registers. Identify any special hazards. Sparks, heat, chemicals, deep water or crush risk all point toward boots and toward specific additional codes. Only now consider comfort, breathability and appearance. These are real factors, but they're tiebreakers, not the deciding criteria. Where XNEXZ Sits, Honestly XNEXZ makes two low-cut safety trainers, PulseX and StrideX, both certified S1PL FO SR under EN ISO 20345:2022+A1:2024. That means S1 base protection, a non-metallic puncture-resistant insert, a fuel-and-oil-resistant outsole and slip resistance. The certificate records no water resistance, no ankle protection and no metatarsal protection, so we don't claim any of them. We built trainers because we think the warehouse, indoor trade and delivery roles described above have been underserved by footwear designed for building sites. That's a specific bet on a specific set of jobs, not a claim that trainers beat boots generally. They don't, and for the site work listed further up this page they aren't close. If you're weighing up trainer options specifically, our S1P safety trainers buying guide walks through what to look for, including from brands other than us. Suitable For / Choose Differently Safety trainers may suit Warehouse pickers, packers and forklift operators Indoor fit-out, decorating and second-fix trades Delivery drivers and depot staff Facilities and light-maintenance teams Retail stockroom and back-of-house workers Car mechanics and workshop staff on sealed floors Anyone on flat ground for long shifts Choose safety boots for Construction, groundworks and demolition Roofing, scaffolding and work at height Outdoor work in wet or cold conditions Welding, foundry and other hot work Agriculture, forestry and landscaping Any role needing S3 or higher certification Any site whose policy specifies boots The Honest Verdict If your ground is uneven, wet, hot or outdoors, buy boots. The coverage is doing real work, and a lighter shoe doesn't compensate for the protection it doesn't have. We sell trainers and we'd still tell you that. If your ground is flat and sealed and you're on it for eight hours or more, boots are asking your legs to carry protection against hazards you don't face. That's the case where trainers win, and it covers far more UK jobs than the industry's site-focused marketing suggests. Everything else, appearance, breathability, break-in time, is a tiebreaker. Get the ground and the rating right first. Try XNEXZ Where It Genuinely Fits If your work is on flat indoor floors, your site accepts S1P, and you want to see whether a lighter shoe changes how your feet feel at the end of a shift, try PulseX or StrideX and tell us honestly how they hold up. We're a new brand earning trust through real feedback, not claims. View PulseX View StrideX Frequently Asked Questions Are safety trainers as safe as safety boots? For toe protection, slip resistance and puncture resistance, a certified trainer meets the same tested thresholds as a certified boot at the same rating. What boots add is ankle coverage, debris protection at the collar, and access to higher ratings like S3. Whether that matters depends entirely on your ground conditions. Can I wear safety trainers on a construction site? Usually not. Most UK construction sites specify S3 as a minimum, and many require boots explicitly in their site rules. Check the site induction requirements before buying, since turning up in the wrong footwear can mean being turned away. Do safety boots really support your ankles? A boot definitely restricts how far the ankle can roll, which is genuinely useful on uneven ground. Whether that restriction reduces injury rates on flat surfaces is less settled, with mixed findings in the research. Match the coverage to your ground rather than relying on the general claim. Which is more comfortable for long shifts? On flat ground, trainers generally win on weight and flexibility, which matters over high step counts. On uneven ground, boots are often more comfortable because the ankle isn't constantly correcting. Comfort depends on the surface as much as the shoe. Are safety trainers cheaper than safety boots? Not reliably. Prices overlap heavily in both directions, and a well-made trainer can cost more than a basic boot. Judge on certification, materials and construction rather than assuming one format is the budget option. What about safety trainer boots, the mid-cut option? They pair a trainer-style sole with a mid-height ankle collar, which suits mixed roles that move between indoor and outdoor work. They're heavier than a low-cut trainer and less protective than a full site boot, which is the trade-off you're accepting. Does XNEXZ make safety boots? No. XNEXZ currently makes two low-cut S1P trainers, PulseX and StrideX. If your work needs boot coverage or an S3 rating, you'll need to look at brands that make them.

Side by Side Safety trainers Safety boots Ankle coverage Below the ankle bone Mid-ankle or higher Typical weight per shoe Around 400 to 600g Around 600 to 900g Common ratings S1, S1P, occasionally S2 S3, S5, S7, plus S1P options Debris protection at the collar Limited Strong Break-in period Usually short Often longer, especially in leather Breathability Generally better, mesh uppers common Generally lower, more enclosed On and off speed Fast Slower, more lace height Off-site appearance Passes as ordinary footwear Visibly workwear Ankle coverage compared across low-cut trainers, mid-cut and high-cut boots A low-cut safety trainer finishes below the ankle bone. A mid-cut boot covers the ankle joint. A high-cut boot extends above it toward the lower shin. Low cut Trainer ankle exposed Mid cut Ankle boot ankle covered High cut Rigger or hiker boot ankle and lower shin ankle bone line The dashed line marks the ankle bone. Everything above it is coverage a trainer does not provide. The Ankle Support Claim, Handled Honestly "Boots support your ankles" is the single most repeated line in safety footwear marketing. It deserves a more careful answer than either side usually gives it. What a boot definitely does is restrict range of motion. A structured collar physically limits how far the joint can roll. On uneven ground, rubble, kerbs, trench edges and scaffolding, that restriction is genuinely useful, and it's why boots are standard on construction sites rather than a marketing preference. What's less settled is whether that restriction meaningfully reduces injury rates on flat, predictable surfaces. Research on high-top versus low-top footwear in sport has produced mixed findings, and some evidence suggests that relying on external support can, over long periods, do less for joint stability than the surrounding muscles do. We're not going to pretend that debate is resolved, and we're certainly not going to resolve it in a blog post written by a company that sells low-cut shoes. The practical takeaway is narrower and more reliable: match the coverage to the ground. Uneven, sloped, cluttered or outdoor ground is a strong argument for a boot regardless of how the wider debate settles. Flat indoor floors are not. When Boots Are Clearly the Right Answer These aren't edge cases. They cover a large share of UK site work, and in every one of them we'd tell you to buy a boot rather than anything we make. Construction, groundworks and demolition. Uneven ground, wet conditions, sharp debris and heavy materials underfoot. Usually S3 as a minimum, which is boot territory anyway. Roofing, scaffolding and civil engineering. Working at height on irregular surfaces, where ankle roll carries far greater consequences. Outdoor work in wet or cold conditions. Boots offer more enclosure and are far more commonly available with water-resistant and waterproof certification. Welding, foundry and hot work. An open collar and sparks are a bad combination. Look for heat-resistant codes and boot coverage. Agriculture, forestry and landscaping. Mud, uneven terrain and heavy machinery all favour full coverage. Anywhere your site policy specifies boots. This overrides every other consideration on this page. When Trainers Are the Better Choice Equally, there's a large category of work where a boot is simply more shoe than the job needs, and the extra weight buys protection against hazards that aren't present. Warehouse and distribution work. Flat sealed floors, long walking distances, and the main hazard being dropped items rather than uneven ground. Indoor trade and fit-out work. Interior joinery, decorating, electrical second-fix and similar, on finished floors. Delivery, courier and depot roles. Frequent in and out of vehicles, high step counts, mostly hard surfaces. Facilities, maintenance and light engineering. Mixed indoor environments where mobility matters more than enclosure. Retail stockrooms and back-of-house. Flat floors, customer-facing appearance sometimes a factor. Roles that cross between work and public settings. Where visibly heavy workwear boots feel out of place. What these have in common is flat, predictable ground and long hours on it. That's the profile where the weight difference starts to matter and the coverage difference stops mattering, a trade-off we look at in more detail in lightweight safety shoes: what you gain. The Middle Ground: Safety Trainer Boots There's a third category worth knowing about. Safety trainer boots, sometimes called hiker-style safety boots, use a trainer's sole unit and construction with a mid-cut ankle collar. They aim to keep some of the lightness and flexibility while adding the collar coverage. They're a genuine compromise rather than a marketing category, and for mixed roles that move between indoor and outdoor work across the week they often make more sense than committing to either extreme. They are, inevitably, heavier than a low-cut trainer and less protective than a full site boot. XNEXZ doesn't currently make one. Two Worked Examples Scenario 1 Warehouse picker, ten-hour shifts, sealed concrete floor Fifteen thousand steps a shift on flat ground. The realistic hazards are dropped stock, box staples and banding wire. Nothing on the floor is uneven, wet or hot. Trainers. The boot's coverage would guard against hazards this role doesn't face, while the extra weight is paid for on every one of those steps. Scenario 2 Groundworker on a residential site through winter Trench edges, loose spoil, standing water, rebar and timber off-cuts underfoot. Ground conditions change through the day and rarely stay flat. Boots, almost certainly S3. This is the case where lightweight trainers are the wrong tool, and no amount of comfort compensates for the missing coverage. What Doesn't Actually Differ A few assumptions are worth clearing up, because they push people toward boots for reasons that don't hold. Toe protection. A 200 joule toe cap is a 200 joule toe cap. A certified trainer and a certified boot meet the identical impact and compression thresholds. Height above the ankle adds nothing to toe protection. Slip resistance. This is a function of the outsole compound and tread pattern, not the height of the collar. A well-designed trainer sole can outperform a poorly designed boot sole. Puncture resistance. Also underfoot, also unrelated to cut height. Both formats can carry P, PL or PS markings. Durability, necessarily. Boots often last longer because they're built heavier, but a well-made trainer can outlast a cheap boot. Construction quality matters more than category. How to Decide Check your site's PPE policy first. If it names a rating or a format, that's your answer and the rest of this list is background reading. Under the PPE at Work Regulations 2022, specifying suitable footwear is your employer's duty, not your judgement call. Describe your ground honestly. Flat and sealed, or uneven, sloped, wet, or covered in loose material? Be honest about the worst day, not the average one. Count your hours and your steps. Over eight hours of walking, weight compounds. Over four hours mostly stationary, it barely registers. Identify any special hazards. Sparks, heat, chemicals, deep water or crush risk all point toward boots and toward specific additional codes. Only now consider comfort, breathability and appearance. These are real factors, but they're tiebreakers, not the deciding criteria. Where XNEXZ Sits, Honestly XNEXZ makes two low-cut safety trainers, PulseX and StrideX, both certified S1PL FO SR under EN ISO 20345:2022+A1:2024. That means S1 base protection, a non-metallic puncture-resistant insert, a fuel-and-oil-resistant outsole and slip resistance. The certificate records no water resistance, no ankle protection and no metatarsal protection, so we don't claim any of them. We built trainers because we think the warehouse, indoor trade and delivery roles described above have been underserved by footwear designed for building sites. That's a specific bet on a specific set of jobs, not a claim that trainers beat boots generally. They don't, and for the site work listed further up this page they aren't close. If you're weighing up trainer options specifically, our S1P safety trainers buying guide walks through what to look for, including from brands other than us. Suitable For / Choose Differently Safety trainers may suit Warehouse pickers, packers and forklift operators Indoor fit-out, decorating and second-fix trades Delivery drivers and depot staff Facilities and light-maintenance teams Retail stockroom and back-of-house workers Car mechanics and workshop staff on sealed floors Anyone on flat ground for long shifts Choose safety boots for Construction, groundworks and demolition Roofing, scaffolding and work at height Outdoor work in wet or cold conditions Welding, foundry and other hot work Agriculture, forestry and landscaping Any role needing S3 or higher certification Any site whose policy specifies boots The Honest Verdict If your ground is uneven, wet, hot or outdoors, buy boots. The coverage is doing real work, and a lighter shoe doesn't compensate for the protection it doesn't have. We sell trainers and we'd still tell you that. If your ground is flat and sealed and you're on it for eight hours or more, boots are asking your legs to carry protection against hazards you don't face. That's the case where trainers win, and it covers far more UK jobs than the industry's site-focused marketing suggests. Everything else, appearance, breathability, break-in time, is a tiebreaker. Get the ground and the rating right first. Try XNEXZ Where It Genuinely Fits If your work is on flat indoor floors, your site accepts S1P, and you want to see whether a lighter shoe changes how your feet feel at the end of a shift, try PulseX or StrideX and tell us honestly how they hold up. We're a new brand earning trust through real feedback, not claims. View PulseX View StrideX Frequently Asked Questions Are safety trainers as safe as safety boots? For toe protection, slip resistance and puncture resistance, a certified trainer meets the same tested thresholds as a certified boot at the same rating. What boots add is ankle coverage, debris protection at the collar, and access to higher ratings like S3. Whether that matters depends entirely on your ground conditions. Can I wear safety trainers on a construction site? Usually not. Most UK construction sites specify S3 as a minimum, and many require boots explicitly in their site rules. Check the site induction requirements before buying, since turning up in the wrong footwear can mean being turned away. Do safety boots really support your ankles? A boot definitely restricts how far the ankle can roll, which is genuinely useful on uneven ground. Whether that restriction reduces injury rates on flat surfaces is less settled, with mixed findings in the research. Match the coverage to your ground rather than relying on the general claim. Which is more comfortable for long shifts? On flat ground, trainers generally win on weight and flexibility, which matters over high step counts. On uneven ground, boots are often more comfortable because the ankle isn't constantly correcting. Comfort depends on the surface as much as the shoe. Are safety trainers cheaper than safety boots? Not reliably. Prices overlap heavily in both directions, and a well-made trainer can cost more than a basic boot. Judge on certification, materials and construction rather than assuming one format is the budget option. What about safety trainer boots, the mid-cut option? They pair a trainer-style sole with a mid-height ankle collar, which suits mixed roles that move between indoor and outdoor work. They're heavier than a low-cut trainer and less protective than a full site boot, which is the trade-off you're accepting. Does XNEXZ make safety boots? No. XNEXZ currently makes two low-cut S1P trainers, PulseX and StrideX. If your work needs boot coverage or an S3 rating, you'll need to look at brands that make them.
What Does SB Mean on Safety Shoes? What It Doesn't Cover
SB stands for Safety Basic. It's the entry point of EN ISO 20345, the level a shoe has to reach before it can legally be sold as safety footwear at all. Everything above it, S1, S2, S3 and beyond, is built on the SB foundation. The confusion around SB comes from treating it as a quality grade. It isn't. An SB shoe can be beautifully made from excellent materials and still be SB, because the rating describes which protective features are certified, not how well the shoe is built. SB certifies one core thing: a toe cap that survives a 200 joule impact and 15 kN of compression. Anti-static properties, a puncture-resistant midsole, a closed heel and water resistance are all absent unless separately added. What SB Actually Requires Under the current EN ISO 20345:2022 revision, an SB-certified shoe must meet the standard's basic requirements. The headline one is toe protection. Impact resistance: the toe cap must withstand a 200 joule impact, roughly equivalent to a 20kg object dropped from around one metre. Compression resistance: the toe cap must withstand 15 kilonewtons of compressive force, the kind of load a wheel or heavy object rolling across the foot would apply. Baseline slip resistance: the 2022 revision brought slip resistance into the mandatory basic requirements, tested on ceramic tile with glycerine. Shoes certified to the older 2011 version may not have been tested this way, which is worth knowing if you're looking at older stock. General construction and material requirements: covering upper, lining, insole and outsole properties, plus chemical compliance. That's the whole certified package. Every additional protective feature you might assume comes as standard is, at SB level, genuinely optional. What SB Does Not Include This is the part that catches people out, because several of these feel like they should be automatic in anything called a safety shoe. What SB certification includes and excludes SB includes a 200 joule toe cap, 15 kilonewton compression resistance and baseline slip resistance. It excludes anti-static properties, heel energy absorption, a closed heel, a puncture-resistant midsole, water resistance and fuel and oil resistance. SB includes ✓ 200 joule toe cap impact ✓ 15 kN toe compression ✓ Baseline slip resistance ✓ Material and chemical compliance SB does not include ✕ Anti-static properties ✕ Heel energy absorption ✕ A closed heel ✕ Puncture-resistant midsole ✕ Water-resistant upper ✕ Fuel and oil resistance Everything in the right-hand column has to be added as a separate certified property before an SB shoe provides it. Two of these deserve a closer look, because they surprise people most often. SB shoes can have an open heel S1 and above require a closed seat region. SB does not. That's why safety clogs, slip-on styles and some backless healthcare and kitchen footwear sit at SB level: the design itself rules out the closed heel that S1 demands. The shoe isn't cutting a corner, it's a different shape by intent. SB shoes are not automatically anti-static Anti-static performance, marked A, is one of the properties S1 adds. An SB shoe may have it, but only if the manufacturer has had it separately tested and marked. If your workplace requires anti-static footwear, an SB marking on its own does not satisfy that requirement. SB, S1 and S1P Side by Side Reading across the rows shows exactly what each step up the ladder buys you. Feature SB S1 S1P 200J toe cap impact ✓ ✓ ✓ 15 kN toe compression ✓ ✓ ✓ Closed seat region ✕ ✓ ✓ Anti-static properties ✕ ✓ ✓ Heel energy absorption ✕ ✓ ✓ Puncture-resistant midsole ✕ ✕ ✓ Water-resistant upper ✕ ✕ ✕ For the full ladder above this point, including S2 through to S7, see our breakdown of safety shoe ratings from SB to S7. When SB Is Genuinely the Right Choice SB gets dismissed as the cheap option, and that's unfair. There are situations where it's the correct specification rather than a compromise. Where the design requires an open heel. Safety clogs in healthcare, laboratory and food-preparation settings often need to be slipped on and off quickly, or need to be easily washable. SB is the only rating those designs can carry. Where SB is combined with the specific codes you need. A shoe marked SB P, for example, has the baseline toe cap plus certified puncture resistance, without the anti-static or energy-absorption requirements. If those are the two hazards your risk assessment identifies, that combination is a precise match rather than a shortfall. Visitor and occasional-use footwear. Site visitors, auditors and office staff crossing a warehouse floor briefly may need toe protection and nothing more. SB overshoes and basic SB footwear are common and appropriate here. The mistake isn't buying SB. It's buying SB while assuming it includes features that only appear at S1 and above. Why Most UK Workplaces Specify S1 or Higher Despite those legitimate uses, S1 and above dominate UK workplace PPE specifications, for a straightforward reason: the properties SB leaves out are the ones most ordinary workplaces actually need. A warehouse floor generates static. Ten hours of standing puts real demand on heel cushioning. A shoe that can slip off at the heel is a trip risk when carrying loads. None of those are exotic hazards, they're everyday conditions, and S1 addresses all three. Under the PPE at Work Regulations 2022, it's your employer's duty to assess the hazards in your role and specify footwear that matches them. If their assessment says S1P and you turn up in SB shoes, the shoes do not meet the requirement no matter how well made they are. That assessment overrides any general guidance, including this article. Two Worked Examples Scenario 1 Hospital kitchen porter in washable clogs The role needs footwear that can be removed quickly, wiped down between shifts, and offers toe protection against dropped pans and trolley wheels. A closed heel would make the shoe harder to clean and slower to change. SB is the appropriate rating here, and the open-heel design is the reason, not a shortcut. Scenario 2 Warehouse operative on a ten-hour shift Long periods standing and walking on hard concrete, static build-up from racking and packaging, plus dropped fixings underfoot. The heel needs cushioning, the shoe needs to stay on the foot, and static needs somewhere to go. SB falls short on three counts. S1 covers the first three, and S1P adds the puncture-resistant midsole for the dropped fixings. How to Check What Your Own Shoes Are Rated The marking is normally printed on the tongue label, stamped inside the collar, or moulded into the insole. Find the base code. SB, S1, S2, S3 and so on. If you see SB with nothing after it, the certified protection is the toe cap and basic requirements only. Read any letters that follow. P, PL, PS, A, E, FO, SR, WPA and similar are separate optional properties, each tested and certified independently. Check the standard version. EN ISO 20345:2022 is the current revision. Older stock may be certified to the 2011 version, which tested slip resistance differently. Compare it against your employer's written PPE requirement, not against what looks reasonable. If the two don't match, raise it rather than assuming it's close enough. Where XNEXZ Sits, Honestly XNEXZ doesn't sell SB footwear. PulseX and StrideX are certified S1PL FO SR on the current CTC certificate under EN ISO 20345:2022+A1:2024, which means S1 base protection, a non-metallic puncture-resistant insert tested with the 4.5mm nail, a fuel-and-oil-resistant outsole and slip resistance. We're not going to argue that SB footwear is inadequate as a category, because for open-heel designs and short-duration use it clearly isn't. What we'd say is narrower: for the light-duty indoor roles we build for, warehouse work, indoor trade work, delivery and facilities, the properties S1 adds are the ones that matter across a full shift, and a puncture-resistant midsole on top of that covers the most common underfoot hazard in those settings. If you want the fuller picture of what that rating does and doesn't cover, it's set out in our complete UK guide to S1P safety shoes. If your role needs S3, waterproof protection, ankle support or specialist certification, XNEXZ isn't the right choice and we'd rather say so. Suitable For / Choose Differently SB may be appropriate for Open-heel safety clogs in healthcare and food preparation Site visitors and auditors needing brief toe protection Office staff crossing a production or warehouse floor occasionally Roles where SB is combined with the exact codes the risk assessment names Laboratory settings where washability outranks a closed heel Choose S1 or higher for Full shifts spent standing or walking: S1 for heel energy absorption Environments with static build-up: S1 for anti-static properties Sharp objects underfoot: S1P for the puncture-resistant midsole Wet floors and washdown areas: S2 Construction, groundworks and outdoor sites: S3 Any role where the PPE policy names a specific rating: follow it exactly The Honest Verdict SB is a real certification with a real test behind it, and it does one job properly: protecting your toes from impact and compression. Treating it as fake or low-grade misreads what the marking means. The risk isn't SB itself, it's the assumption gap. People buy SB believing they're getting the anti-static, cushioned, closed-heel, puncture-resistant package that the phrase "safety shoe" suggests. For most everyday UK work, that package starts at S1, and the underfoot protection starts at S1P. Read the letters after the S, and the gap disappears. Try XNEXZ Where It Genuinely Fits If your workplace accepts S1P footwear and you want a more modern, lightweight-feeling option, try PulseX or StrideX on a real shift and tell us honestly how the fit, comfort and daily performance hold up.

SB stands for Safety Basic, the entry level of EN ISO 20345. It certifies a toe cap that withstands a 200 joule impact and 15 kN of compression, plus the standard's basic construction and slip-resistance requirements. Are SB safety shoes any good? SB describes the certified feature set, not build quality, so an SB shoe can be very well made. It's the right choice where an open-heel design is needed or where toe protection alone matches the risk assessment. It falls short where anti-static, heel cushioning or puncture resistance are required. What's the difference between SB and S1? S1 adds three things to SB: anti-static properties, energy absorption in the heel, and a closed seat region. Everything else in the base package stays the same. Are SB safety shoes legal for work in the UK? SB footwear is legitimate certified PPE and can be worn where the employer's risk assessment specifies it. What matters is whether SB matches the assessed hazards for your role, not whether SB is permitted in general. Do SB shoes have a steel toe cap? They have a toe cap certified to 200 joules, but the material varies. Steel, aluminium and composite caps can all meet that threshold. The SB marking tells you the protection level, not what the cap is made from. Can an SB shoe have puncture resistance? Yes. Puncture resistance is an optional property marked P, PL or PS, and it can be added to SB. A shoe marked SB P has the base toe cap plus a certified puncture-resistant midsole, without the anti-static and energy-absorption properties that S1 requires. Why are safety clogs usually only SB rated? Because S1 and above require a closed seat region, and an open-heel clog cannot meet that requirement by design. The SB rating reflects the shape of the shoe rather than a lower standard of manufacture.

The SB rating reflects the shape of the shoe rather than a lower standard of manufacture.
What Does S1PL Mean on Safety Shoes? PL vs PS Explained
If your safety shoes are marked S1PL or S1PS rather than plain S1P, nothing has gone wrong with the label. The extra letter records which test nail the puncture-resistant insert was tested against, and it only appears on shoes with a non-metallic insert. This guide explains the three puncture codes under EN ISO 20345, why the 2022 revision split non-metallic inserts into two categories, and how to read your own label. It also covers one widespread myth about these codes that we have a direct interest in correcting, because it applies to our own shoes. P means a metallic insert. PL and PS both mean a non-metallic insert, tested with a 4.5mm nail and a 3mm nail respectively. All three have to withstand the same 1,100 newton force. What the P, PL and PS Codes Actually Mean Under EN ISO 20345:2022, a safety shoe earns a puncture-resistance marking when its midsole insert survives a standard penetration test at a minimum force of 1,100 newtons. That threshold is the same for every code. What changes is the insert material and the shape of the nail used to test it. Puncture-resistance codes under EN ISO 20345:2022 Code Insert material Test nail diameter Minimum force P Metallic, usually a steel plate 4.5mm truncated point 1,100 N PL Non-metallic, usually a textile or composite insert 4.5mm, the larger point 1,100 N PS Non-metallic, usually a textile or composite insert 3.0mm, the smaller point 1,100 N The letters are simple mnemonics once you see them written out: L for the large nail, S for the small nail. Both attach only to non-metallic inserts, which is why you will never see "S1PL" on a shoe with a steel midsole plate. Why Non-Metallic Inserts Needed Their Own Codes Before the 2022 revision, a shoe with a steel plate and a shoe with a textile insert could both be marked simply "P," even though the two materials fail in different ways. A steel plate is a continuous sheet. A nail that meets it is stopped by the sheet regardless of how fine the point is. A non-metallic insert is typically a woven or layered structure, and a fine point can sometimes push between the fibres and pass through without the material itself actually breaking. The insert holds up perfectly well against a blunt 4.5mm nail and still lets a thin needle-like object through. That's the gap the PL and PS codes close. Rather than letting one marking cover both outcomes, the standard now records which nail the insert was actually tested against, so the buyer can judge whether that test matches the hazard on their own floor. Comparison of the 4.5mm and 3mm test nails used for PL and PS codes The PL test uses a wider 4.5 millimetre point which spreads force across more of the insert. The PS test uses a narrower 3 millimetre point which concentrates the same 1,100 newton force into a smaller contact area. PL test nail 4.5mm point, larger contact area PS test nail 3mm point, force concentrated 4.5mm 3mm Non-metallic insert Non-metallic insert Same force 1,100 N both tests A narrower point spreads the same force over less area, so PS is the more demanding test Both codes are tested at 1,100 newtons. Only the nail geometry changes, and a finer point concentrates that force into a smaller contact patch. Is PS Better Protection Than PL? Against fine, sharp objects, yes. A PS-marked insert has passed a test with a narrower point, which concentrates the same force into a smaller area and is harder for the material to resist. If your workplace has thin wire, staples, needles, or fine metal swarf on the floor, PS is the more relevant certification. For most everyday workplaces, though, the honest answer is that the difference rarely decides anything. The hazards that actually cause underfoot injuries in warehouses, workshops and indoor trade work are nails, screws, box staples and glass fragments, which the 4.5mm test represents reasonably well. Employers specifying footwear for those environments generally treat PL as adequate, and PL is by far the more common marking on shoes sold into UK light-duty roles. It's also worth keeping the codes in proportion. No insert of any code removes the risk of a puncture injury. Certification means the insert passed a defined laboratory test at a defined force, not that it will stop every object in every real-world situation, at any angle, at any point on the sole, throughout the life of the shoe. How Metallic and Non-Metallic Inserts Compare The choice between P and PL/PS is not only about the test nail. The two insert types behave differently in daily wear, and each has genuine trade-offs. Metallic insert (P) Non-metallic insert (PL or PS) Typical material Stainless or carbon steel plate Woven aramid textile or composite laminate Weight Heavier Lighter Flexibility Stiffer underfoot More flexible, moves closer to the foot Sole coverage Often less than the full footprint, limited by plate shape Can usually be cut closer to the full footprint Thermal conduction Conducts cold and heat more readily Conducts less readily Corrosion Can corrode if the sole is damaged and moisture reaches it Does not rust Fine-point resistance Continuous sheet, unaffected by point size Depends on the code, PS covers the finer point Neither is universally superior. Steel gives you point-size independence and a long track record. Non-metallic gives you lower weight, more flexibility and often better sole coverage. We look at this trade-off in more depth in our comparison of Kevlar and steel midsoles. The Metal Detector Myth, and Why It Matters to Us The most common misunderstanding about PL and PS codes is that they mean the shoe is metal-free and will pass through a metal detector. They don't. The codes describe the midsole insert only. They say nothing about the toe cap, the eyelets, the shank, or any other component. This matters to us directly, because it applies to our own products. XNEXZ PulseX and StrideX are both certified with a non-metallic anti-penetration insert, which is exactly why they carry the PL marking. But both models use a metallic aluminium toe cap, recorded as such on the certificate. A metal detector will find that toe cap. If your workplace genuinely requires fully metal-free footwear, for airport security screening, certain food-processing lines, or magnetic-sensitive environments, PulseX and StrideX are not suitable, and no amount of PL marking changes that. If you need a fully metal-free shoe, look for one with a composite toe cap alongside the non-metallic insert. Our guide to aluminium, composite and steel toe caps explains which materials are and aren't detectable. What XNEXZ Actually Carries On the current EU type examination certificate, issued by CTC (Notified Body 0075) on 10 April 2026 under EN ISO 20345:2022+A1:2024, both PulseX and StrideX are listed under the category S1PL FO SR. Read left to right, that means: S1 base protection, puncture resistance through a non-metallic insert tested with the 4.5mm nail (PL), a fuel-and-oil-resistant outsole (FO), and slip resistance (SR). The certificate records the insert nature as non-metallic and the toe cap nature as metallic. It records no water resistance, no heat resistance, and no metatarsal protection, so we don't claim any of those. We publish the full marking rather than shortening it to "S1P" because the extra letters are the part that tells you which test was actually run. If you want the wider context on what S1P covers and where its limits sit, that's in our complete UK guide to S1P safety shoes. How to Read Your Own Shoe's Label The marking is usually printed on the tongue label, the inside collar, or a stamp on the insole. Work through it in this order: Find the base rating first. S1, S2, S3 and so on tell you the core protection package before any add-on codes. Look for P, PL or PS immediately after it. No letter at all means no certified puncture resistance in that shoe. Check what follows. FO, SR, HRO, CI, WR and similar codes are separate optional properties, each tested independently. Match it against your employer's PPE requirement. If the risk assessment specifies PS and your shoes are marked PL, the shoes do not meet the requirement, however good they otherwise are. If the label has worn off and you can't confirm the marking, treat the shoe as uncertified for that property until you can check the manufacturer's documentation. Under the UK's PPE at Work Regulations 2022, it's your employer's duty to specify and verify the correct footwear rating for your role. Two Worked Examples Scenario 1 Warehouse picker on a dry unit floor The realistic underfoot hazards are box staples, banding wire off-cuts and the occasional dropped fixing. Nothing routinely on the floor is finer than a standard staple leg. A PL-marked shoe covers this well. Specifying PS would add a certification the role never actually calls on. Scenario 2 Workshop with fine metal swarf Machining produces thin, sharp metal shavings that can sit upright on the floor and are considerably finer than a 4.5mm nail. This is exactly the hazard the smaller test point was introduced to represent. PS is the more relevant marking here, and the employer's risk assessment should say so explicitly rather than leaving it to the wearer to judge. Suitable For / Choose Differently PL marking, such as PulseX or StrideX, may suit Warehouse pickers, packers and forklift operators Painters, decorators and interior fit-out teams Car mechanics and garage workers Delivery and depot staff working mostly indoors Facilities and light-maintenance teams Retail stockroom workers Look for a different specification if Fine wire, needles or metal swarf are present: look for PS Your risk assessment names a specific code: follow it exactly You need genuinely metal-free footwear: composite toe cap plus non-metallic insert The floor is wet as well as sharp: S3 rather than S1P The work is construction, groundworks or demolition: higher-rated footwear The Honest Verdict PL and PS are not marketing tiers, and neither one is a premium version of the other. They're a record of which test nail the insert faced, introduced so that buyers could stop guessing what a plain "P" on a non-metallic insert actually covered. For most everyday indoor work, PL is the appropriate and widely accepted marking. For environments with genuinely fine sharp hazards, PS earns its place. The one thing neither code does is make a shoe metal-free, and that's the misunderstanding most worth clearing up before you buy. Try XNEXZ Where It Genuinely Fits If your workplace accepts S1P footwear with a PL-marked insert and a metallic toe cap, we'd like you to try PulseX or StrideX on a real shift and tell us honestly how the fit, comfort and daily performance hold up. We're a new brand earning trust through real feedback, not claims. View PulseX View StrideX Frequently Asked Questions What does S1PL mean on a safety shoe? S1PL means S1 base protection plus a non-metallic puncture-resistant insert tested with the larger 4.5mm nail. The L identifies the test nail size, not a lower grade of protection. What is the difference between PL and PS? Both mark a non-metallic insert tested at 1,100 newtons. PL uses a 4.5mm test point and PS uses a narrower 3mm point, which concentrates the same force into a smaller area and is the more demanding of the two tests. Does a PL or PS marking mean the shoe is metal-free? No. The code describes the midsole insert only. The toe cap, eyelets and other components may still be metallic. Check the toe cap material separately if you need footwear that passes a metal detector. Is PS worth paying more for? Only if your workplace actually has fine sharp hazards such as wire, needles or metal swarf. For typical nails, screws and staples in indoor light-duty work, PL is generally accepted and adequate. Your employer's risk assessment should make the call. Why doesn't a steel midsole get a PL or PS code? Because a steel plate is a continuous sheet, its resistance doesn't change with the size of the nail point. The two-code split was created specifically to distinguish between test outcomes for woven and composite inserts, which can behave differently against a finer point. Which code do XNEXZ shoes carry? PulseX and StrideX are both certified S1PL FO SR under EN ISO 20345:2022+A1:2024. The insert is non-metallic and tested with the 4.5mm nail, while the toe cap is metallic aluminium. Can a shoe carry both PL and PS? In practice you'll see one code on the marking. An insert that passes the smaller 3mm nail test is marked PS, which is the more demanding of the two, so there's no need to also state PL alongside it.

S2 Safety Shoes vs S1P: The Honest Difference
S2 and S1P protect against different hazards, not different amounts of the same one. S1P adds a puncture-resistant midsole; S2 adds a water-resistant upper. A shoe can do one job well and offer nothing for the other. XNEXZ sells S1P certified safety shoes, not S2, so we have every reason to explain this honestly rather than blur the line. This guide covers what each rating requires under EN ISO 20345, why they get confused, and which one actually matches your job. S1P adds puncture resistance. S2 adds water resistance. Neither includes both, only S3 does. Why S2 and S1P Get Confused So Often The confusion is understandable, because the labels look sequential. S1, then S1P, then S2, then S3: read left to right, it looks like a straight line of rising protection. It isn't. The core ladder under EN ISO 20345 runs SB → S1 → S2 → S3 → S4 → S5 → S6 → S7, with each step adding requirements on top of the last. The letter P is not a step on that ladder. It's an additional property code that attaches to S1 to form the hybrid marking "S1P." S1P sits beside S2, not between S1 and S2, because it's S1 plus one extra feature, puncture resistance, while S2 is a separate step up the ladder that adds a different extra feature, a water-resistant upper. That structural detail answers "which one is better" on its own: neither. They're both S1 with a different upgrade attached, aimed at two different hazards. EN ISO 20345 rating ladder with S1P shown as an add-on to S1 SB leads to S1, S2 and S3 in a straight ladder. S1P branches off S1 as an attached feature rather than a step on the main ladder. SB 200J toe cap S1 + anti-static, heel S2 + water-resistant upper S3 + punct. resist. + cleats S1P an attached feature, not a ladder step The main ladder runs SB to S3 and beyond. S1P branches off S1 as an added feature, which is why it sits beside S2 rather than between S1 and S2. What Each Rating Actually Requires The table below builds from the base rating upward, showing exactly what's added, and what's still missing, at each level relevant to this comparison. EN ISO 20345:2022, SB to S3 requirements Rating Builds on Adds Still missing SB Base level 200-joule / 15kN toe cap, the baseline every rating below builds on Anti-static, puncture resistance, water resistance S1 SB Anti-static properties, energy-absorbing heel, closed-heel construction Puncture resistance, water resistance S1P S1 Puncture-resistant midsole insert Water-resistant upper S2 S1 Water-resistant upper, tested to the WRU/WPA method Puncture-resistant midsole S3 S2 Puncture-resistant midsole plus a cleated outsole Nothing on this list; the most complete of the five A Quick Visual Comparison Scanning left to right instead of reading paragraphs: here's exactly which core protections each rating includes. Rating 200J toe impact Anti-static + heel energy absorption Puncture-resistant midsole Water-resistant upper SB ✓ ✕ ✕ ✕ S1 ✓ ✓ ✕ ✕ S1P ✓ ✓ ✓ ✕ S2 ✓ ✓ ✕ ✓ S3 ✓ ✓ ✓ ✓ What S1P Adds, and What It Leaves Out S1P certification means a shoe has passed every S1 test: 200-joule toe impact, 15kN compression, anti-static performance, energy absorption in the heel, plus one more requirement, a penetration-resistant midsole insert designed to stop sharp objects such as nails, screws, or glass reaching the foot from underneath. Under EN ISO 20345, that insert has to withstand at least 1,100 newtons of force from a standard test nail before it can carry the "P" marking. There are two ways a midsole can earn that marking. A metallic insert is tested with a sharpened steel nail. A non-metallic insert, increasingly common because it won't set off a metal detector, is tested with a blunter nail instead, since a thin metal nail can sometimes slip between the fibres of a non-metallic material without the material actually failing. That non-metallic version is marked "PL" when tested with a larger 4.5mm nail, or "PS" when tested with a smaller 3mm nail. What S1P does not include is any water-resistance testing for the upper. Rain, wet floors, or standing water will reach the foot through an S1P shoe in much the same way they would through an ordinary trainer. That isn't a flaw in the certification; S1P was never designed to address moisture. It simply means an S1P shoe is the wrong tool for a consistently wet environment, no matter how good its puncture protection is. What S2 Adds, and What It Leaves Out S2 certification also builds on S1, but in the opposite direction. Instead of a puncture-resistant midsole, S2 requires the upper material to resist water penetration and absorption, usually marked WRU or WPA, for a defined test period under laboratory conditions. The test exposes the upper to water for a set time and measures how much moisture gets through and how much the material itself soaks up. It's worth being precise here: water-resistant is not the same as waterproof. The WRU/WPA test measures resistance over a set testing window, not permanent submersion or continuous standing water. It's a genuine, useful upgrade for wet-floor and light-rain conditions; it isn't a guarantee that feet stay dry indefinitely. What S2 does not include is any puncture-resistant midsole. An S2 shoe that keeps a wet floor out offers no more underfoot protection against a dropped screw or a stray nail than a standard S1 shoe. S1P vs S2, Side by Side S1P S2 Builds on S1 S1 Main added protection Puncture-resistant midsole Water-resistant upper Resists water? No Yes, to the tested WRU/WPA standard, not full waterproofing Resists underfoot punctures? Yes, to the tested P standard No Best suited to Dry environments with underfoot sharp-object risk Wet-floor or light-rain environments with low puncture risk Typical settings Warehouses, workshops, indoor fit-out, general trade work Washdown areas, some food production, certain outdoor light-duty roles Which One Do You Actually Need? Three questions settle this faster than any comparison table: Is the floor under your feet usually dry, or does it regularly get wet from washing, rain, or spills? What's the realistic risk of standing on something sharp: loose fixings, off-cuts, glass, metal swarf? Does your employer's PPE policy or risk assessment already specify a rating for your role? If question three has a clear answer, that answer overrides everything else on this page. Under the UK's PPE at Work Regulations 2022, it's the employer's duty to assess workplace hazards and specify the correct footwear rating for each role. A general guide like this one is a starting point, not a substitute for that assessment. Once you've answered honestly, the rating usually picks itself: Mostly dry floor, sharp-object risk underfoot: S1P. Regularly wet floor, low puncture risk: S2. Both hazards present at once, which describes a lot of construction and groundworks: S3, covered in more depth in S1P vs S3 safety shoes. Two Quick, Real Examples Scenario 1 Warehouse picker on a dry unit floor The floor is polished concrete and stays dry. The realistic hazard is loose banding wire, box staples, and the occasional dropped fixing. Water simply isn't a factor here. S1P is the correct rating. S2 would add a feature this role never actually uses. Scenario 2 Catering prep area with regular washdown The floor gets hosed and mopped several times a shift, and staff can stand in shallow surface water for short stretches. The floor itself is smooth tile, so underfoot puncture risk is low. S2 is the correct rating. The water-resistant upper is doing real work, while a puncture-resistant midsole would be guarding against a hazard that barely exists in this kitchen. Where XNEXZ Fits Into This, Honestly XNEXZ's current range, PulseX and StrideX, is certified S1P, not S2. On the current EN ISO 20345:2022+A1:2024 test certificate, both models are listed under category S1PL FO SR: S1P protection delivered through a non-metallic penetration-resistant insert (the "PL" element), plus a fuel-and-oil-resistant outsole (FO) and slip resistance (SR). The certificate records no water-resistant upper, no WRU or WPA marking, so we don't, and won't, describe these shoes as water-resistant or suitable for wet-floor work. If your job is genuinely dry underfoot and the hazard is sharp debris, that's exactly the gap PulseX and StrideX are built for. The full detail on what S1P certification covers is in our S1P safety shoes guide. If your job regularly puts your feet in water, on a washdown floor, or outdoors in the rain, XNEXZ isn't the right choice for that role, and we'd rather tell you that now than have you find out on shift.

That range is a genuine advantage if your work moves between different hazard types across the week, or if your site has a pre-approved brand list that already includes them. We're not trying to out-range brands that have been doing this for decades. XNEXZ's angle is a modern, trainer-style S1P shoe for the specific everyday jobs where S1P is the correct call, not a claim to cover every hazard a workplace might present. The Honest Verdict S2 is not an upgrade on S1P, and S1P is not an upgrade on S2. They solve different problems. The only real mistake is assuming one code quietly includes the other's protection: check what your job actually exposes your feet to, then match the rating to that, not to which number looks higher. Try XNEXZ Where It Genuinely Fits If your workplace accepts S1P footwear and your feet stay mostly dry on shift, we'd like you to try PulseX or StrideX and tell us honestly how the fit, comfort and daily performance hold up. We're a new brand building trust through real feedback, not claims, good or bad, we want to hear it. View PulseX View StrideX Frequently Asked Questions Is S1P waterproof? No. S1P certification tests toe protection, anti-static performance, energy absorption and puncture resistance; it doesn't test the upper for water resistance at all. Wet floors and rain will reach the foot through an S1P shoe. Is S2 better than S1P overall? Neither is "better" in general, they protect against different hazards. S2 is the stronger choice for wet-floor or light-rain work with low puncture risk; S1P is the stronger choice for dry environments with sharp-object risk underfoot. Can a safety shoe be both S1P and S2 at once? Not under those two labels together. A shoe that combines a water-resistant upper with a puncture-resistant midsole is classified S3, not "S1P and S2." S3 is effectively S2 plus puncture resistance, plus a cleated outsole. What does the "FO" marking mean next to S1P? FO stands for fuel and oil resistant outsole. It's an optional marking under the current standard, tested by checking how the outsole material holds up after contact with diesel and mineral oil. It has nothing to do with puncture or water resistance. Is S1P more common than S2 in the UK? S1P is generally the more widely stocked rating for indoor and light-duty trade footwear in the UK, since most everyday workplaces are dry underfoot with occasional sharp-object risk. S2 tends to be more of a specialist choice for wet-floor and washdown roles. Do I need S2 safety shoes for a commercial kitchen job? It depends on your specific floor conditions and your employer's risk assessment. Some kitchen and food-service roles specify S2 for washdown areas, while others accept S1P where floors stay largely dry. Check your workplace's PPE policy rather than assuming either way. Does XNEXZ offer an S2 safety shoe? Not currently. PulseX and StrideX are both certified S1P, with no water-resistant upper on the test certificate. If your role needs certified water resistance, look for an S2 or S3 rated shoe from a brand that offers one.
S2 Safety Shoes vs S1P: The Honest Difference
S2 and S1P protect against different hazards, not different amounts of the same one. S1P adds a puncture-resistant midsole; S2 adds a water-resistant upper. A shoe can do one job well and offer nothing for the other. XNEXZ sells S1P certified safety shoes, not S2, so we have every reason to explain this honestly rather than blur the line. This guide covers what each rating requires under EN ISO 20345, why they get confused, and which one actually matches your job. S1P adds puncture resistance. S2 adds water resistance. Neither includes both, only S3 does. Why S2 and S1P Get Confused So Often The confusion is understandable, because the labels look sequential. S1, then S1P, then S2, then S3: read left to right, it looks like a straight line of rising protection. It isn't. The core ladder under EN ISO 20345 runs SB → S1 → S2 → S3 → S4 → S5 → S6 → S7, with each step adding requirements on top of the last. The letter P is not a step on that ladder. It's an additional property code that attaches to S1 to form the hybrid marking "S1P." S1P sits beside S2, not between S1 and S2, because it's S1 plus one extra feature, puncture resistance, while S2 is a separate step up the ladder that adds a different extra feature, a water-resistant upper. That structural detail answers "which one is better" on its own: neither. They're both S1 with a different upgrade attached, aimed at two different hazards. EN ISO 20345 rating ladder with S1P shown as an add-on to S1 SB leads to S1, S2 and S3 in a straight ladder. S1P branches off S1 as an attached feature rather than a step on the main ladder. SB 200J toe cap S1 + anti-static, heel S2 + water-resistant upper S3 + punct. resist. + cleats S1P an attached feature, not a ladder step The main ladder runs SB to S3 and beyond. S1P branches off S1 as an added feature, which is why it sits beside S2 rather than between S1 and S2. What Each Rating Actually Requires The table below builds from the base rating upward, showing exactly what's added, and what's still missing, at each level relevant to this comparison.

Rating 200J toe impact Anti-static + heel energy absorption Puncture-resistant midsole Water-resistant upper SB ✓ ✕ ✕ ✕ S1 ✓ ✓ ✕ ✕ S1P ✓ ✓ ✓ ✕ S2 ✓ ✓ ✕ ✓ S3 ✓ ✓ ✓ ✓ What S1P Adds, and What It Leaves Out S1P certification means a shoe has passed every S1 test: 200-joule toe impact, 15kN compression, anti-static performance, energy absorption in the heel, plus one more requirement, a penetration-resistant midsole insert designed to stop sharp objects such as nails, screws, or glass reaching the foot from underneath. Under EN ISO 20345, that insert has to withstand at least 1,100 newtons of force from a standard test nail before it can carry the "P" marking. There are two ways a midsole can earn that marking. A metallic insert is tested with a sharpened steel nail. A non-metallic insert, increasingly common because it won't set off a metal detector, is tested with a blunter nail instead, since a thin metal nail can sometimes slip between the fibres of a non-metallic material without the material actually failing. That non-metallic version is marked "PL" when tested with a larger 4.5mm nail, or "PS" when tested with a smaller 3mm nail. What S1P does not include is any water-resistance testing for the upper. Rain, wet floors, or standing water will reach the foot through an S1P shoe in much the same way they would through an ordinary trainer. That isn't a flaw in the certification; S1P was never designed to address moisture. It simply means an S1P shoe is the wrong tool for a consistently wet environment, no matter how good its puncture protection is. What S2 Adds, and What It Leaves Out S2 certification also builds on S1, but in the opposite direction. Instead of a puncture-resistant midsole, S2 requires the upper material to resist water penetration and absorption, usually marked WRU or WPA, for a defined test period under laboratory conditions. The test exposes the upper to water for a set time and measures how much moisture gets through and how much the material itself soaks up. It's worth being precise here: water-resistant is not the same as waterproof. The WRU/WPA test measures resistance over a set testing window, not permanent submersion or continuous standing water. It's a genuine, useful upgrade for wet-floor and light-rain conditions; it isn't a guarantee that feet stay dry indefinitely. What S2 does not include is any puncture-resistant midsole. An S2 shoe that keeps a wet floor out offers no more underfoot protection against a dropped screw or a stray nail than a standard S1 shoe. S1P vs S2, Side by Side S1P S2 Builds on S1 S1 Main added protection Puncture-resistant midsole Water-resistant upper Resists water? No Yes, to the tested WRU/WPA standard, not full waterproofing Resists underfoot punctures? Yes, to the tested P standard No Best suited to Dry environments with underfoot sharp-object risk Wet-floor or light-rain environments with low puncture risk Typical settings Warehouses, workshops, indoor fit-out, general trade work Washdown areas, some food production, certain outdoor light-duty roles Which One Do You Actually Need? Three questions settle this faster than any comparison table: Is the floor under your feet usually dry, or does it regularly get wet from washing, rain, or spills? What's the realistic risk of standing on something sharp: loose fixings, off-cuts, glass, metal swarf? Does your employer's PPE policy or risk assessment already specify a rating for your role? If question three has a clear answer, that answer overrides everything else on this page. Under the UK's PPE at Work Regulations 2022, it's the employer's duty to assess workplace hazards and specify the correct footwear rating for each role. A general guide like this one is a starting point, not a substitute for that assessment. Once you've answered honestly, the rating usually picks itself: Mostly dry floor, sharp-object risk underfoot: S1P. Regularly wet floor, low puncture risk: S2. Both hazards present at once, which describes a lot of construction and groundworks: S3, covered in more depth in S1P vs S3 safety shoes. Two Quick, Real Examples Scenario 1 Warehouse picker on a dry unit floor The floor is polished concrete and stays dry. The realistic hazard is loose banding wire, box staples, and the occasional dropped fixing. Water simply isn't a factor here. S1P is the correct rating. S2 would add a feature this role never actually uses. Scenario 2 Catering prep area with regular washdown The floor gets hosed and mopped several times a shift, and staff can stand in shallow surface water for short stretches. The floor itself is smooth tile, so underfoot puncture risk is low. S2 is the correct rating. The water-resistant upper is doing real work, while a puncture-resistant midsole would be guarding against a hazard that barely exists in this kitchen. Where XNEXZ Fits Into This, Honestly XNEXZ's current range, PulseX and StrideX, is certified S1P, not S2. On the current EN ISO 20345:2022+A1:2024 test certificate, both models are listed under category S1PL FO SR: S1P protection delivered through a non-metallic penetration-resistant insert (the "PL" element), plus a fuel-and-oil-resistant outsole (FO) and slip resistance (SR). The certificate records no water-resistant upper, no WRU or WPA marking, so we don't, and won't, describe these shoes as water-resistant or suitable for wet-floor work. If your job is genuinely dry underfoot and the hazard is sharp debris, that's exactly the gap PulseX and StrideX are built for. The full detail on what S1P certification covers is in our S1P safety shoes guide. If your job regularly puts your feet in water, on a washdown floor, or outdoors in the rain, XNEXZ isn't the right choice for that role, and we'd rather tell you that now than have you find out on shift.

S3 Safety Shoes: When S1P Isn't Enough
S3 safety shoes are certified under EN ISO 20345 and combine everything S1P offers, a 200-joule toe cap, antistatic properties, an energy-absorbing heel and a puncture-resistant insert, with two additions that S1P does not have: water resistance of the upper and a cleated outsole. Those two additions are the reason S3 is the default specification on most UK construction sites. We make S1P footwear and no S3 at all, so this article recommends other manufacturers throughout. If your work needs S3, we would rather send you to a brand that builds it properly than blur the line. The Short Answer S3 safety shoes add upper water resistance (WPA) and a cleated outsole to the S1P package. They suit wet ground, outdoor work and uneven terrain. S3 is not fully waterproof, and footwear that keeps water out over a long shift carries the WR marking in categories S6 and S7. What This Guide Covers What S3 safety shoes are What S3 adds that S1P does not Are S3 shoes waterproof? What S3L and S3S mean Which jobs require S3 When S1P is genuinely enough S3 shoes or S3 boots? What to look for beyond the code Which brands make good S3 footwear Cost and service life Verifying an S3 certificate Why we are recommending competitors Frequently asked questions What Are S3 Safety Shoes? Quick Answer S3 is a Class I category under EN ISO 20345 built up from S2. It requires a 200-joule toe cap, closed heel, antistatic properties, an energy-absorbing heel, upper water resistance, a penetration-resistant insert and a cleated outsole. The categories are cumulative, so the quickest way to understand S3 is to see how it is assembled. Layer What it adds Tested value SB (base) Protective toe cap 200 J impact, 15 kN compression S1 Closed seat region, antistatic (A), energy absorption (E) 0.1 to 1,000 MΩ; at least 20 J S2 Water penetration and absorption resistance of the upper (WPA) Tested over 60 minutes S3 Penetration-resistant insert plus a cleated outsole At least 1,100 N; cleat height at least 2.5 mm How S3 is built up from the base requirements of EN ISO 20345:2022. Two structural points worth knowing. S3 is Class I, meaning leather and other materials, which covers virtually every safety shoe and boot on the UK market. Class II is all-rubber or all-polymeric moulded footwear, and that is where S4 and S5 live. And under the 2022 revision of the standard, slip resistance became a mandatory basic requirement for every certified shoe, so an S3 shoe has already passed a slip test on ceramic tile with a soap solution before any additional marking is considered. If you want the whole code set side by side, our safety shoe ratings explained guide, SB to S7 lays out every category in one table, and the underlying standard is covered in our EN ISO 20345 certification guide. What Does S3 Add That S1P Does Not? Quick Answer Exactly two things: water penetration and absorption resistance of the upper, marked WPA, and a cleated outsole with a cleat height of at least 2.5 mm. Toe cap, antistatic build, energy-absorbing heel and puncture insert are identical in both categories. Water resistance of the upper (WPA) WPA certifies that the upper material resists water penetration and absorption when tested over a defined period. It replaced the older WRU marking in the 2022 revision. In practice it rules out open mesh construction and requires a denser leather, coated microfibre or membrane-backed upper. This is why S3 footwear tends to run warmer than S1P footwear. Breathability and water resistance are opposing properties, and a shoe cannot maximise both. If your main complaint about safety footwear is hot feet, understand that moving up to S3 will usually make that worse, not better. Our comparison of mesh vs leather uppers in safety shoes explains the trade-off. The cleated outsole The standard defines a cleat as a protruding part of the outsole surface, and sets a minimum cleat height of 2.5 mm for cemented, direct-injected and vulcanised soles. Anything below that is treated as uncleated. For all-rubber and all-polymeric footwear the threshold is 4 mm. On mud, wet grass, gravel and loose spoil, cleats do two jobs: they bite into soft ground, and the channels between them shed material so the tread keeps working. A flat sole on a wet clay slope simply skates. The counter-intuitive part is worth stating clearly. On smooth indoor concrete or vinyl, deep cleats can grip less well than a flatter, finely siped pattern, because lugs reduce the rubber-to-floor contact area. An aggressive tread looks safer indoors and often is not. There is more detail in our guide to non-slip safety shoes, and the direct category comparison sits in S1P vs S3 safety shoes. Are S3 Safety Shoes Waterproof? Quick Answer No. S3 certifies water resistance of the upper material only. Water can still enter at the tongue, collar and lace holes. Whole-footwear water resistance is a separate marking, WR, which defines the newer S6 and S7 categories. This is the most common and most expensive misunderstanding in UK safety footwear buying, so it deserves a plain answer rather than a hedge. Marking What is tested What it means in the rain None (S1, S1P) Nothing Wets through quickly WPA (S2, S3) The upper material, in isolation Resists splashes and damp ground; water still enters at the tongue and collar WR (S6, S7) The whole shoe as an assembly Designed to keep water out in sustained wet conditions If you are standing in wet grass at 7am, walking a flooded compound, or working outdoors through a British winter, WPA will not keep your socks dry. S7 is the specification you actually want, and it is still under-stocked by UK retailers relative to S3 because it only arrived with the 2022 revision. Ask for it by name. A Practical Note Some manufacturers add a waterproof membrane to S3 footwear without certifying the whole shoe to WR, and describe it in the product copy as waterproof. That may well perform, but it is a manufacturer's claim rather than a tested marking. If waterproofing genuinely matters to your shift, look for WR on the label rather than the word on the page. What Do S3L and S3S Mean? Quick Answer They are S3 with a non-metallic penetration-resistant insert. S3L was tested with a 4.5 mm point, S3S with a finer 3 mm point. Plain S3 uses a metallic insert. All three certify the same minimum penetration force of 1,100 N. The suffixes arrived with the 2022 revision and are still poorly explained in UK retail listings, which often show only "S3" regardless of what is inside the sole. Code Insert Test point Underfoot effect S3 Metallic plate 4.5 mm Rigid, partial footbed coverage, conducts cold, heavier S3L Non-metallic textile 4.5 mm Flexes with the foot, near-full coverage, lighter S3S Non-metallic textile 3 mm As S3L, plus tested against thinner sharp objects Which to choose depends on your ground. Roofing nails, screws and timber offcuts are well represented by the 4.5 mm test. Fine wire, staples and thin swarf argue for S3S. And if your site's PPE list specifies a metal plate by wording rather than by tested performance, a non-metallic insert will not satisfy it even though the force rating is identical. Our comparison of Kevlar vs steel midsoles covers how the two behave in use. Which Jobs Require S3 Safety Shoes? Quick Answer S3 is the usual minimum for construction, groundworks, civils, roofing, scaffolding, landscaping, utilities, outdoor yards and any role on wet or uneven ground. The workplace risk assessment sets the actual requirement, not the job title. Work Why S3 Consider going further Construction and groundworks Wet ground, uneven terrain, nails and rebar underfoot S7 for sustained wet; boots for ankle support Roofing and scaffolding Weather exposure, ladder and rung work, fall-risk stability LG marking where ladders are used daily Civils and highways Outdoor exposure, aggregate and loose ground High-visibility footwear where specified Landscaping and grounds maintenance Wet grass, mud, soft ground, tool drops S5 wellingtons for standing water Utilities and fieldwork Mixed terrain, excavation edges, all-weather work Specialist markings depending on the utility Outdoor yards, depots and loading bays Wet concrete, vehicle movement, cage and pallet impact S3 with SR for greasy yard surfaces Commercial kitchens and wash-down Standing water, grease, frequent cleaning HRO for hot contact; S4 or S5 for full wash-down Agriculture and forestry Mud, water, uneven ground, heavy tools Chainsaw-specific footwear where relevant Treat this as a starting point for a conversation with your safety officer. Two sites in the same trade can differ completely, and UK law makes the risk assessment decisive rather than the job description. Employers must also supply required PPE free of charge, which is covered in our guide to the UK PPE at Work Regulations. When Is S1P Genuinely Enough? Quick Answer S1P is sufficient for dry indoor work with impact and puncture risk and no exposure to water or loose ground: warehousing, vehicle workshops, indoor fit-out, facilities, stockrooms and light assembly, where the employer accepts it. Over-specifying is a real cost, not a safe default. An S3 shoe on a dry warehouse floor is heavier, warmer and, because of the cleats, potentially no better on smooth concrete. If your work genuinely has no water and no loose ground, S1P gives you identical toe and puncture protection in a lighter shoe. The test we would apply honestly: buy for the harder half of your day. A picker who spends forty minutes on the loading bay in January is not an indoor worker for footwear purposes, and a decorator who works outside for one week in four should be specified at the higher requirement. Averaging your conditions is how people end up wet. Where S1P does apply, our complete S1P safety shoes guide covers the category in full, and S1, S1P, S2 or S3 compares the four codes most UK buyers weigh up. Should You Buy S3 Shoes or S3 Boots? Quick Answer Safety boot ratings use the identical SB to S7 codes, so an S3 boot and an S3 shoe have passed the same tests. Boots add ankle coverage, debris exclusion and stability on broken ground, none of which is part of the category code. There is no separate standard for boots. If your site specifies S3, both formats meet it, and the choice is about coverage rather than certification. Factor S3 shoe S3 boot Certified protection Identical Identical Ankle support None Substantial Debris and water entry at the collar Higher risk Lower risk Weight and heat Lower Higher Break-in time Shorter Longer Best suited to Mixed indoor and light outdoor Broken ground, excavation, all-weather site work For construction safety boots specifically, many principal contractors require boot height as a site rule independent of the category code, so check the induction paperwork rather than assuming an S3 shoe will be accepted. One further point: if ankle protection is required rather than ankle support, look for the AN marking, which is a separately tested property. Plenty of boots do not carry it. What Should You Look For Beyond the S3 Code? Quick Answer The code is a floor, not a specification. Compare outsole compound, tread depth and self-cleaning geometry, lining and membrane construction, lacing and collar sealing, insert type, weight, and whether the brand offers your size and width. Two S3 shoes at the same price can perform very differently over a winter, and none of that difference shows in the category code. Outsole compound. Rubber grips better than PU on wet, oily and cold surfaces and resists abrasion better on aggregate. PU is lighter and cushions well but wears faster on rough ground. Dual-density constructions try to get both. See our comparison of PU vs rubber outsoles. Tread geometry, not just depth. Look for open channels that shed mud rather than a dense pattern that packs solid. A clogged sole has no grip regardless of certification. How the water resistance is achieved. A treated leather upper behaves differently from a membrane lining. Membranes keep water out longer but take longer to dry once soaked through the collar. Collar and tongue sealing. A gusseted or bellows tongue is the single most useful feature for keeping water and debris out, and it is rarely mentioned in listings. Insert type. Metallic P, or non-metallic PL or PS, and whether your site specifies one by wording. Weight, with the size stated. A weight figure without a size attached is not comparable. S3 typically runs 1,000 to 1,600 g per pair. Size and width availability. If a brand does not build your fit properly, nothing else on this list matters. Our general purchasing checklist covers the rest of the process in buying safety shoes in the UK. Which Brands Make Good S3 Safety Footwear? Quick Answer Established UK-available manufacturers with deep S3 ranges include Portwest, Cofra, uvex, Amblers Safety, V12 Footwear, Caterpillar, Timberland PRO, Solid Gear, DeWalt, Puma Safety and Base Protection. Each has different strengths across boots, fit options and specialist markings. We do not make S3, so this is a straightforward recommendation rather than a comparison weighted in our favour. If you need Worth looking at Why Broad S3 range at contract volume Portwest, Cofra Deep catalogues, stock depth and distribution across UK suppliers S3 boots for heavy site work Caterpillar, Timberland PRO, Amblers, Solid Gear Long track records in boot construction for construction and civils Technical fit and lightweight S3 uvex, Solid Gear, Base Protection Developed fit systems and athletic-influenced S3 constructions Wide fittings and women's lasts uvex, Portwest, V12 Footwear Dedicated lasts and multiple width options rather than scaled-down men's sizes Waterproof S7 or WR-marked footwear Portwest, Cofra, Amblers, Solid Gear Established waterproof lines, though S7 stock is still building across the market Metal-free S3 for detection environments uvex, Cofra, Solid Gear Composite toe caps with non-metallic inserts across the range Trade and DIY availability on the high street DeWalt, Caterpillar, Amblers Wide UK retail distribution and easy replacement We have written standalone reviews of some of these, including Cofra safety shoes, Puma safety shoes and Base safety shoes. Verify current specifications, certification and pricing directly with the manufacturer or retailer before buying, because ranges change and a model name can carry different certifications across seasons. What Do S3 Safety Shoes Cost, and How Long Do They Last? Quick Answer S3 footwear in the UK generally runs from about £35 to £150, sitting slightly above comparable S1P. Expect 6 to 12 months in daily outdoor use, less on abrasive ground. Replace on condition rather than by calendar. Price band What you typically get Realistic service life £35 to £60 Entry S3 construction, basic outsole compound, limited fit range 4 to 8 months in daily site use £60 to £100 Better rubber compounds, gusseted tongues, wider sizing 8 to 14 months £100 to £150 Membrane linings, technical fit systems, S7 and specialist markings 12 to 20 months Outdoor work is harder on footwear than indoor work, so an S3 shoe on a wet site will not last as long as an S1P shoe on a dry warehouse floor at the same price. Replace immediately if the toe cap becomes visible, the cleats wear smooth, the upper splits at the flex line, the sole separates, or the shoe takes a heavy impact. A toe cap is certified against a single tested event, not a service life of them. How Do You Verify an S3 Shoe Is Genuinely Certified? Quick Answer Read the permanent marking inside the tongue or collar for the standard, year, category and size. Then request the type-examination certificate and Declaration of Conformity. Safety footwear is Category II PPE and cannot be self-certified. Find the permanent marking. Inside the tongue, collar or quarter lining, not on a swing tag or box. Check the category matches the listing. If the page says S3 and the label says S1P, the label is correct and the listing is not. Check the standard version. EN ISO 20345:2022 or 2022+A1:2024 is current. A 2011 certificate remains valid until it expires, but the vocabulary will be older, and any listing still quoting SRA, SRB or SRC has not been updated. Request the type-examination certificate. It names an independent conformity assessment body and its four-digit identification number, along with validity dates. Request the Declaration of Conformity and read the user instructions. Both are required, and the instructions state the limits of protection. In Great Britain both CE and UKCA marking are accepted for PPE, so do not reject a shoe for carrying one rather than the other. Northern Ireland continues to follow EU rules. Why We Are Telling You to Buy Someone Else's Shoes Quick Answer Xnexz makes S1P-family footwear only, certified in category S1PL FO SR. We produce no S3, S6 or S7 footwear, no cleated outsoles, no water-resistance marking and no boots. If your work needs S3, we are not an option. An article about S3 published by a company that does not make S3 could easily have been a soft sell for buying down a category. We are not going to write that, because a worker who buys S1P for an S3 site loses a shift at the gate and gets wet feet in the meantime. The honest position: our footwear is trainer-format, certified to EN ISO 20345:2022+A1:2024 in category S1PL FO SR, and intended for dry indoor light-duty settings where an employer accepts S1P. It has no water-resistance marking of any kind, no cleated outsole, no ankle support, no metatarsal or cut protection, and it is not fire or flame resistant. Our sizing runs UK 7 to 11 in a single width, so we do not serve most women's sizes or anyone needing a wide fit. Established manufacturers have longer track records, wider ranges, more sizes and fits, boots with ankle support and specialist certifications we simply do not hold. For wet, outdoor and heavy-duty work several of them are the better choice, not a fallback. Our different proposition, for workers whose sites accept S1P, is set out in the complete UK safety shoes buyer's guide, and in the story behind Xnexz safety shoes if you want the background. Frequently Asked Questions What does S3 mean on safety shoes? S3 is a category under EN ISO 20345 covering a 200-joule toe cap, closed heel, antistatic properties, an energy-absorbing heel, water resistance of the upper, a penetration-resistant insert and a cleated outsole. It is the usual minimum on UK construction sites. Are S3 safety shoes waterproof? No. S3 certifies water resistance of the upper material only, and water can still enter at the tongue, collar or lace holes. Whole-footwear water resistance is marked WR and defines the S6 and S7 categories. What is the difference between S1P and S3? S3 adds two things to S1P: water resistance of the upper, marked WPA, and a cleated outsole. The toe cap, antistatic properties, energy-absorbing heel and puncture-resistant insert are identical in both. Do construction safety boots have to be S3? Not by law, but most UK sites specify S3 as a minimum in their site rules, and many principal contractors additionally require boot height rather than a shoe. Check the site induction paperwork for the exact requirement. What is the difference between S3 and S7? S7 is S3 plus whole-footwear water resistance, marked WR. If your work involves sustained wet conditions rather than occasional damp, S7 is the correct specification and S3 will leave your feet wet. Is S3 the same for boots and shoes? Yes. Safety boot ratings use the identical SB to S7 codes, so an S3 boot and an S3 shoe have passed the same tests. The boot adds height, which brings ankle support and better exclusion of water and debris. What does S3L mean? S3L is S3 with a non-metallic penetration-resistant insert tested using a 4.5 mm point. S3S uses a finer 3 mm point. Both certify the same minimum penetration force of 1,100 N as plain S3, which uses a metal plate. Can I wear S3 shoes indoors? Yes, they are certified for any environment that S1P covers. Be aware that S3 footwear is usually heavier and warmer, and that deep cleats can offer less grip than a flatter tread on smooth indoor floors. The Honest Verdict S3 exists for a specific set of conditions: water on the ground, loose or uneven terrain, and sharp objects underfoot. Where those conditions are present it is the right specification, and buying below it is a compliance failure rather than a saving. Where they are absent, S3 adds weight and heat without adding protection, and S1P covers the same impact and puncture risk in a lighter shoe. The one refinement most buyers miss is S7. If your work is genuinely wet rather than occasionally damp, WR-marked footwear is what you are looking for, and asking for S7 by name is the fastest way to find it.

S3 Safety Shoes: When S1P Isn't Enough
S3 safety shoes are certified under EN ISO 20345 and combine everything S1P offers, a 200-joule toe cap, antistatic properties, an energy-absorbing heel and a puncture-resistant insert, with two additions that S1P does not have: water resistance of the upper and a cleated outsole. Those two additions are the reason S3 is the default specification on most UK construction sites. We make S1P footwear and no S3 at all, so this article recommends other manufacturers throughout. If your work needs S3, we would rather send you to a brand that builds it properly than blur the line. The Short Answer S3 safety shoes add upper water resistance (WPA) and a cleated outsole to the S1P package. They suit wet ground, outdoor work and uneven terrain. S3 is not fully waterproof, and footwear that keeps water out over a long shift carries the WR marking in categories S6 and S7. What This Guide Covers What S3 safety shoes are What S3 adds that S1P does not Are S3 shoes waterproof? What S3L and S3S mean Which jobs require S3 When S1P is genuinely enough S3 shoes or S3 boots? What to look for beyond the code Which brands make good S3 footwear Cost and service life Verifying an S3 certificate Why we are recommending competitors Frequently asked questions What Are S3 Safety Shoes? Quick Answer S3 is a Class I category under EN ISO 20345 built up from S2. It requires a 200-joule toe cap, closed heel, antistatic properties, an energy-absorbing heel, upper water resistance, a penetration-resistant insert and a cleated outsole. The categories are cumulative, so the quickest way to understand S3 is to see how it is assembled. Layer What it adds Tested value SB (base) Protective toe cap 200 J impact, 15 kN compression S1 Closed seat region, antistatic (A), energy absorption (E) 0.1 to 1,000 MΩ; at least 20 J S2 Water penetration and absorption resistance of the upper (WPA) Tested over 60 minutes S3 Penetration-resistant insert plus a cleated outsole At least 1,100 N; cleat height at least 2.5 mm How S3 is built up from the base requirements of EN ISO 20345:2022. Two structural points worth knowing. S3 is Class I, meaning leather and other materials, which covers virtually every safety shoe and boot on the UK market. Class II is all-rubber or all-polymeric moulded footwear, and that is where S4 and S5 live. And under the 2022 revision of the standard, slip resistance became a mandatory basic requirement for every certified shoe, so an S3 shoe has already passed a slip test on ceramic tile with a soap solution before any additional marking is considered. If you want the whole code set side by side, our safety shoe ratings explained guide, SB to S7 lays out every category in one table, and the underlying standard is covered in our EN ISO 20345 certification guide. What Does S3 Add That S1P Does Not? Quick Answer Exactly two things: water penetration and absorption resistance of the upper, marked WPA, and a cleated outsole with a cleat height of at least 2.5 mm. Toe cap, antistatic build, energy-absorbing heel and puncture insert are identical in both categories. Water resistance of the upper (WPA) WPA certifies that the upper material resists water penetration and absorption when tested over a defined period. It replaced the older WRU marking in the 2022 revision. In practice it rules out open mesh construction and requires a denser leather, coated microfibre or membrane-backed upper. This is why S3 footwear tends to run warmer than S1P footwear. Breathability and water resistance are opposing properties, and a shoe cannot maximise both. If your main complaint about safety footwear is hot feet, understand that moving up to S3 will usually make that worse, not better. Our comparison of mesh vs leather uppers in safety shoes explains the trade-off. The cleated outsole The standard defines a cleat as a protruding part of the outsole surface, and sets a minimum cleat height of 2.5 mm for cemented, direct-injected and vulcanised soles. Anything below that is treated as uncleated. For all-rubber and all-polymeric footwear the threshold is 4 mm. On mud, wet grass, gravel and loose spoil, cleats do two jobs: they bite into soft ground, and the channels between them shed material so the tread keeps working. A flat sole on a wet clay slope simply skates. The counter-intuitive part is worth stating clearly. On smooth indoor concrete or vinyl, deep cleats can grip less well than a flatter, finely siped pattern, because lugs reduce the rubber-to-floor contact area. An aggressive tread looks safer indoors and often is not. There is more detail in our guide to non-slip safety shoes, and the direct category comparison sits in S1P vs S3 safety shoes. Are S3 Safety Shoes Waterproof? Quick Answer No. S3 certifies water resistance of the upper material only. Water can still enter at the tongue, collar and lace holes. Whole-footwear water resistance is a separate marking, WR, which defines the newer S6 and S7 categories. This is the most common and most expensive misunderstanding in UK safety footwear buying, so it deserves a plain answer rather than a hedge. Marking What is tested What it means in the rain None (S1, S1P) Nothing Wets through quickly WPA (S2, S3) The upper material, in isolation Resists splashes and damp ground; water still enters at the tongue and collar WR (S6, S7) The whole shoe as an assembly Designed to keep water out in sustained wet conditions If you are standing in wet grass at 7am, walking a flooded compound, or working outdoors through a British winter, WPA will not keep your socks dry. S7 is the specification you actually want, and it is still under-stocked by UK retailers relative to S3 because it only arrived with the 2022 revision. Ask for it by name. A Practical Note Some manufacturers add a waterproof membrane to S3 footwear without certifying the whole shoe to WR, and describe it in the product copy as waterproof. That may well perform, but it is a manufacturer's claim rather than a tested marking. If waterproofing genuinely matters to your shift, look for WR on the label rather than the word on the page. What Do S3L and S3S Mean? Quick Answer They are S3 with a non-metallic penetration-resistant insert. S3L was tested with a 4.5 mm point, S3S with a finer 3 mm point. Plain S3 uses a metallic insert. All three certify the same minimum penetration force of 1,100 N. The suffixes arrived with the 2022 revision and are still poorly explained in UK retail listings, which often show only "S3" regardless of what is inside the sole. Code Insert Test point Underfoot effect S3 Metallic plate 4.5 mm Rigid, partial footbed coverage, conducts cold, heavier S3L Non-metallic textile 4.5 mm Flexes with the foot, near-full coverage, lighter S3S Non-metallic textile 3 mm As S3L, plus tested against thinner sharp objects Which to choose depends on your ground. Roofing nails, screws and timber offcuts are well represented by the 4.5 mm test. Fine wire, staples and thin swarf argue for S3S. And if your site's PPE list specifies a metal plate by wording rather than by tested performance, a non-metallic insert will not satisfy it even though the force rating is identical. Our comparison of Kevlar vs steel midsoles covers how the two behave in use. Which Jobs Require S3 Safety Shoes? Quick Answer S3 is the usual minimum for construction, groundworks, civils, roofing, scaffolding, landscaping, utilities, outdoor yards and any role on wet or uneven ground. The workplace risk assessment sets the actual requirement, not the job title. Work Why S3 Consider going further Construction and groundworks Wet ground, uneven terrain, nails and rebar underfoot S7 for sustained wet; boots for ankle support Roofing and scaffolding Weather exposure, ladder and rung work, fall-risk stability LG marking where ladders are used daily Civils and highways Outdoor exposure, aggregate and loose ground High-visibility footwear where specified Landscaping and grounds maintenance Wet grass, mud, soft ground, tool drops S5 wellingtons for standing water Utilities and fieldwork Mixed terrain, excavation edges, all-weather work Specialist markings depending on the utility Outdoor yards, depots and loading bays Wet concrete, vehicle movement, cage and pallet impact S3 with SR for greasy yard surfaces Commercial kitchens and wash-down Standing water, grease, frequent cleaning HRO for hot contact; S4 or S5 for full wash-down Agriculture and forestry Mud, water, uneven ground, heavy tools Chainsaw-specific footwear where relevant Treat this as a starting point for a conversation with your safety officer. Two sites in the same trade can differ completely, and UK law makes the risk assessment decisive rather than the job description. Employers must also supply required PPE free of charge, which is covered in our guide to the UK PPE at Work Regulations. When Is S1P Genuinely Enough? Quick Answer S1P is sufficient for dry indoor work with impact and puncture risk and no exposure to water or loose ground: warehousing, vehicle workshops, indoor fit-out, facilities, stockrooms and light assembly, where the employer accepts it. Over-specifying is a real cost, not a safe default. An S3 shoe on a dry warehouse floor is heavier, warmer and, because of the cleats, potentially no better on smooth concrete. If your work genuinely has no water and no loose ground, S1P gives you identical toe and puncture protection in a lighter shoe. The test we would apply honestly: buy for the harder half of your day. A picker who spends forty minutes on the loading bay in January is not an indoor worker for footwear purposes, and a decorator who works outside for one week in four should be specified at the higher requirement. Averaging your conditions is how people end up wet. Where S1P does apply, our complete S1P safety shoes guide covers the category in full, and S1, S1P, S2 or S3 compares the four codes most UK buyers weigh up. Should You Buy S3 Shoes or S3 Boots? Quick Answer Safety boot ratings use the identical SB to S7 codes, so an S3 boot and an S3 shoe have passed the same tests. Boots add ankle coverage, debris exclusion and stability on broken ground, none of which is part of the category code. There is no separate standard for boots. If your site specifies S3, both formats meet it, and the choice is about coverage rather than certification. Factor S3 shoe S3 boot Certified protection Identical Identical Ankle support None Substantial Debris and water entry at the collar Higher risk Lower risk Weight and heat Lower Higher Break-in time Shorter Longer Best suited to Mixed indoor and light outdoor Broken ground, excavation, all-weather site work For construction safety boots specifically, many principal contractors require boot height as a site rule independent of the category code, so check the induction paperwork rather than assuming an S3 shoe will be accepted. One further point: if ankle protection is required rather than ankle support, look for the AN marking, which is a separately tested property. Plenty of boots do not carry it. What Should You Look For Beyond the S3 Code? Quick Answer The code is a floor, not a specification. Compare outsole compound, tread depth and self-cleaning geometry, lining and membrane construction, lacing and collar sealing, insert type, weight, and whether the brand offers your size and width. Two S3 shoes at the same price can perform very differently over a winter, and none of that difference shows in the category code. Outsole compound. Rubber grips better than PU on wet, oily and cold surfaces and resists abrasion better on aggregate. PU is lighter and cushions well but wears faster on rough ground. Dual-density constructions try to get both. See our comparison of PU vs rubber outsoles. Tread geometry, not just depth. Look for open channels that shed mud rather than a dense pattern that packs solid. A clogged sole has no grip regardless of certification. How the water resistance is achieved. A treated leather upper behaves differently from a membrane lining. Membranes keep water out longer but take longer to dry once soaked through the collar. Collar and tongue sealing. A gusseted or bellows tongue is the single most useful feature for keeping water and debris out, and it is rarely mentioned in listings. Insert type. Metallic P, or non-metallic PL or PS, and whether your site specifies one by wording. Weight, with the size stated. A weight figure without a size attached is not comparable. S3 typically runs 1,000 to 1,600 g per pair. Size and width availability. If a brand does not build your fit properly, nothing else on this list matters. Our general purchasing checklist covers the rest of the process in buying safety shoes in the UK. Which Brands Make Good S3 Safety Footwear? Quick Answer Established UK-available manufacturers with deep S3 ranges include Portwest, Cofra, uvex, Amblers Safety, V12 Footwear, Caterpillar, Timberland PRO, Solid Gear, DeWalt, Puma Safety and Base Protection. Each has different strengths across boots, fit options and specialist markings. We do not make S3, so this is a straightforward recommendation rather than a comparison weighted in our favour. If you need Worth looking at Why Broad S3 range at contract volume Portwest, Cofra Deep catalogues, stock depth and distribution across UK suppliers S3 boots for heavy site work Caterpillar, Timberland PRO, Amblers, Solid Gear Long track records in boot construction for construction and civils Technical fit and lightweight S3 uvex, Solid Gear, Base Protection Developed fit systems and athletic-influenced S3 constructions Wide fittings and women's lasts uvex, Portwest, V12 Footwear Dedicated lasts and multiple width options rather than scaled-down men's sizes Waterproof S7 or WR-marked footwear Portwest, Cofra, Amblers, Solid Gear Established waterproof lines, though S7 stock is still building across the market Metal-free S3 for detection environments uvex, Cofra, Solid Gear Composite toe caps with non-metallic inserts across the range Trade and DIY availability on the high street DeWalt, Caterpillar, Amblers Wide UK retail distribution and easy replacement We have written standalone reviews of some of these, including Cofra safety shoes, Puma safety shoes and Base safety shoes. Verify current specifications, certification and pricing directly with the manufacturer or retailer before buying, because ranges change and a model name can carry different certifications across seasons. What Do S3 Safety Shoes Cost, and How Long Do They Last? Quick Answer S3 footwear in the UK generally runs from about £35 to £150, sitting slightly above comparable S1P. Expect 6 to 12 months in daily outdoor use, less on abrasive ground. Replace on condition rather than by calendar. Price band What you typically get Realistic service life £35 to £60 Entry S3 construction, basic outsole compound, limited fit range 4 to 8 months in daily site use £60 to £100 Better rubber compounds, gusseted tongues, wider sizing 8 to 14 months £100 to £150 Membrane linings, technical fit systems, S7 and specialist markings 12 to 20 months Outdoor work is harder on footwear than indoor work, so an S3 shoe on a wet site will not last as long as an S1P shoe on a dry warehouse floor at the same price. Replace immediately if the toe cap becomes visible, the cleats wear smooth, the upper splits at the flex line, the sole separates, or the shoe takes a heavy impact. A toe cap is certified against a single tested event, not a service life of them. How Do You Verify an S3 Shoe Is Genuinely Certified? Quick Answer Read the permanent marking inside the tongue or collar for the standard, year, category and size. Then request the type-examination certificate and Declaration of Conformity. Safety footwear is Category II PPE and cannot be self-certified. Find the permanent marking. Inside the tongue, collar or quarter lining, not on a swing tag or box. Check the category matches the listing. If the page says S3 and the label says S1P, the label is correct and the listing is not. Check the standard version. EN ISO 20345:2022 or 2022+A1:2024 is current. A 2011 certificate remains valid until it expires, but the vocabulary will be older, and any listing still quoting SRA, SRB or SRC has not been updated. Request the type-examination certificate. It names an independent conformity assessment body and its four-digit identification number, along with validity dates. Request the Declaration of Conformity and read the user instructions. Both are required, and the instructions state the limits of protection. In Great Britain both CE and UKCA marking are accepted for PPE, so do not reject a shoe for carrying one rather than the other. Northern Ireland continues to follow EU rules. Why We Are Telling You to Buy Someone Else's Shoes Quick Answer Xnexz makes S1P-family footwear only, certified in category S1PL FO SR.

Frequently Asked Questions What does S3 mean on safety shoes? S3 is a category under EN ISO 20345 covering a 200-joule toe cap, closed heel, antistatic properties, an energy-absorbing heel, water resistance of the upper, a penetration-resistant insert and a cleated outsole. It is the usual minimum on UK construction sites. Are S3 safety shoes waterproof? No. S3 certifies water resistance of the upper material only, and water can still enter at the tongue, collar or lace holes. Whole-footwear water resistance is marked WR and defines the S6 and S7 categories. What is the difference between S1P and S3? S3 adds two things to S1P: water resistance of the upper, marked WPA, and a cleated outsole. The toe cap, antistatic properties, energy-absorbing heel and puncture-resistant insert are identical in both. Do construction safety boots have to be S3? Not by law, but most UK sites specify S3 as a minimum in their site rules, and many principal contractors additionally require boot height rather than a shoe. Check the site induction paperwork for the exact requirement. What is the difference between S3 and S7? S7 is S3 plus whole-footwear water resistance, marked WR. If your work involves sustained wet conditions rather than occasional damp, S7 is the correct specification and S3 will leave your feet wet. Is S3 the same for boots and shoes? Yes. Safety boot ratings use the identical SB to S7 codes, so an S3 boot and an S3 shoe have passed the same tests. The boot adds height, which brings ankle support and better exclusion of water and debris. What does S3L mean? S3L is S3 with a non-metallic penetration-resistant insert tested using a 4.5 mm point. S3S uses a finer 3 mm point. Both certify the same minimum penetration force of 1,100 N as plain S3, which uses a metal plate. Can I wear S3 shoes indoors? Yes, they are certified for any environment that S1P covers. Be aware that S3 footwear is usually heavier and warmer, and that deep cleats can offer less grip than a flatter tread on smooth indoor floors.

S1P vs S3 Safety Shoes: Which Do You Need?
S1P and S3 safety shoes share four things: a 200-joule toe cap, antistatic properties, an energy-absorbing heel and a puncture-resistant insert. S3 adds two more, upper water resistance and a cleated outsole. That is the entire difference, and those two additions are what decide which one your job needs. This is a decision, not a ranking. S3 is not a better version of S1P for every worker, and paying more for it will not help you if your floor is dry indoor concrete. Below is the comparison, then a straight decision tree that takes about a minute to work through. The Short Answer Choose S1P for dry indoor work with sharp debris underfoot. Choose S3 for wet ground, outdoor work or uneven terrain. If any part of your shift happens outside or on wet flooring, S3 is the correct specification. S1P vs S3 Safety Shoes: The Difference in One Table Feature S1P S3 200 J toe cap Yes Yes Closed seat region Yes Yes Antistatic (A) Yes Yes Energy-absorbing heel (E) Yes Yes Puncture-resistant insert Yes Yes Upper water resistance (WPA) No Yes Cleated outsole No Yes Whole-footwear waterproofing (WR) No No, that is S7 Typical environment Dry indoor floors Wet ground, outdoors, mixed terrain Typical pair weight, UK 9 700 to 1,000 g 1,000 to 1,600 g Only two rows differ. Everything above them is identical protection. Because the protective package is otherwise the same, the common assumption that S3 is "safer" is wrong in a specific way. S3 is not more protective against impact or puncture. It is more protective against water and loose ground. If neither of those is present in your work, S3 buys you weight you do not need. The full code set is laid out in our safety shoe ratings explained guide, SB to S7. The Two Differences That Actually Decide It Upper water resistance (WPA) WPA certifies that the upper material resists water penetration and absorption. It replaced the older WRU marking in the 2022 revision of the standard. In practice it rules out open mesh construction and requires a denser leather, coated or membrane-backed upper. What WPA does not mean is waterproof. It tests the upper material, not the shoe as an assembly, so water can still enter at the tongue, the lace holes or the collar. If you need footwear that genuinely keeps water out over a long wet shift, the marking you want is WR, which appears in categories S6 and S7. Buying S3 expecting a waterproof shoe is the most common disappointment in this category. The cleated outsole S3 requires a cleated outsole, meaning defined lugs with channels between them. On mud, wet grass, gravel and loose ground this is what clears material away and keeps the tread biting. Here is the part that surprises people: on a smooth indoor floor, deep cleats can grip worse than a flatter, finely siped pattern, because lugs reduce the contact area between rubber and floor. An aggressive tread looks safer and, on polished warehouse concrete, often is not. There is more on this in our guide to non-slip safety shoes. The Decision Tree: Which One Do You Need? Quick Answer Work through five questions in order. A yes to any of the first three means S3 or higher. Only if all three are no does S1P become the right specification, and your employer's risk assessment still overrides the outcome. Does your employer's risk assessment specify a category?Yes: that is your answer. Stop here. A specification of S3 cannot be met with S1P footwear, however well made.No or unsure: ask your supervisor or safety officer in writing, then continue. Does any part of your shift happen outdoors?Yes: choose S3. Loading bays, yards, deliveries, car parks and site walks all count. A UK winter makes an hour outdoors a wet hour.No: continue. Is your floor ever wet, greasy or washed down?Yes: choose S3, or S2 if there is no sharp debris underfoot.No: continue. Is the ground uneven, loose or cluttered?Yes: choose S3, and consider a boot rather than a shoe for ankle support.No: continue. Are there sharp objects on the floor, such as nails, staples, screws or swarf?Yes: S1P is the right specification.No: S1 may be sufficient and usually costs less. If you answered yes at question two, nothing further in this article changes your answer. Buy S3. When S1P Is Enough, and When It Is Not Quick Answer S1P suits dry indoor roles with impact and puncture risk, including warehousing, vehicle workshops, indoor fit-out, facilities and stockroom work. It is not enough for construction, roofing, groundworks, wash-down areas, outdoor depots or cold stores. S1P Is Usually Right For Warehouse picking, packing and dispatch Vehicle workshops and garages, ideally with FO Indoor fit-out, second fix and decorating Facilities, light maintenance and security Retail stockroom and back of house Light assembly and indoor manufacturing You Need S3 or Higher For Construction, groundworks, civils and demolition Roofing, scaffolding and work at height Outdoor yards, depots and loading bays Kitchens and wash-down areas Landscaping, utilities and fieldwork Any role where the ground is wet or broken One judgement worth applying honestly: buy for the harder half of your day. A warehouse operative who spends forty minutes on the loading bay in January is not an indoor worker for footwear purposes. Mixed roles should be specified at the higher requirement, not averaged. Can You Wear S1P Safety Shoes on a Construction Site? Quick Answer Usually not. Most UK construction sites specify S3 as a minimum because of wet ground and uneven terrain, and many principal contractors also require boots for ankle support. S1P may be accepted for dry indoor fit-out or site office work. Site rules are set by the principal contractor and recorded in the site induction, so the answer varies. What does not vary is the consequence of getting it wrong: footwear that does not meet the specified category is refused at the gate, and you lose the shift. Where S1P is sometimes accepted on a construction project, it is typically for second fix, decorating, indoor fit-out, commissioning or site office roles, once the building is watertight and the ground floor is clean. Even then, get it confirmed in writing rather than assuming. Our guide to construction safety shoes in the UK covers what site rules actually require. Does S3 Weigh More and Cost More? Quick Answer Generally yes on both counts. A water-resistant upper and a cleated outsole both add material, so S3 footwear typically weighs 200 to 500 g more per pair than comparable S1P footwear and sits slightly higher in price. The weight difference is real but should not drive the decision. If your work requires S3, a lighter S1P shoe is not a compromise, it is a non-compliant purchase. The useful move is to compare within the category: there are genuinely lighter and heavier S3 options, and that is the choice actually available to you. On price, the gap is usually modest. Both categories span roughly £30 to £120 in the UK, with S3 sitting a little higher for equivalent build quality. Before comparing prices at all, check whether your employer supplies the footwear, since required PPE must be provided free of charge. That is covered in our guide to the UK PPE at Work Regulations. What About S2, S6 and S7? Quick Answer S2 has upper water resistance but no puncture insert. S6 is S2 plus whole-footwear water resistance. S7 is S3 plus whole-footwear water resistance, making it the correct choice for sustained wet outdoor work. Rating Puncture insert Water resistance Cleated outsole S1P Yes None No S2 No Upper only (WPA) No S3 Yes Upper only (WPA) Yes S6 No Whole footwear (WR) No S7 Yes Whole footwear (WR) Yes If you have been choosing between S1P and S3 because your work is genuinely wet rather than merely damp, S7 is probably the specification you actually want. It is the newest of these categories, introduced in the 2022 revision of the standard, and it is still under-stocked by UK retailers compared with S3. The full explanation sits in our EN ISO 20345 certification guide, and the four-way comparison most buyers need is in S1, S1P, S2 or S3 safety shoe rating. Where Xnexz Sits, and When to Buy S3 Instead Quick Answer Xnexz makes S1P-family footwear only, certified in category S1PL FO SR. If your answer to the decision tree above was S3, S6 or S7, we do not make what you need and you should buy from a brand that does. We will be direct about this, because a comparison article written by a manufacturer is worth nothing otherwise. Xnexz produces two trainer-format models certified to EN ISO 20345:2022+A1:2024 in category S1PL FO SR. The Xnexz StrideX S1P safety shoe is the streetwear-influenced option, intended for dry indoor light-duty work where an employer accepts S1P. What that means for this comparison. We make no S3, S6 or S7 footwear. Our shoes carry no water-resistance marking of any kind and do not have a cleated outsole. We do not make boots, so we offer no ankle support. Our sizing runs UK 7 to 11 in a single width, which means we do not serve most women's sizes or anyone needing a wide fit. If your work is wet, outdoors or on broken ground, established manufacturers including Portwest, Cofra, uvex, Amblers, V12, Caterpillar and Timberland PRO all offer deep S3 and waterproof ranges with boot formats and wider fit options. For that work they are the better choice, not a fallback. Our own position is narrow and we would rather say so than blur it. There is a fuller account in our complete S1P safety shoes guide, and the whole category is mapped in the UK safety shoes buyer's guide. Frequently Asked Questions Is S3 better than S1P? Not universally. S3 adds upper water resistance and a cleated outsole to the S1P package, which makes it better for wet and outdoor work. For dry indoor floors it adds weight without adding useful protection, since the toe cap and puncture insert are identical. What is the main difference between S1P and S3? Two things. S3 has upper water resistance, marked WPA, and a cleated outsole. Every other certified property, including the 200-joule toe cap, antistatic build, energy-absorbing heel and puncture-resistant insert, is the same in both. Are S3 safety shoes waterproof? No. S3 certifies water resistance of the upper material only, and water can still enter at the tongue, collar or lace holes. Whole-footwear water resistance is a separate marking, WR, which appears in categories S6 and S7. Can I wear S1P instead of S3 if my site says S3? No. A site specification is a compliance requirement, not a recommendation. S1P footwear will not satisfy an S3 requirement regardless of build quality or price, and you may be refused entry. Do S1P and S3 have the same toe cap? Yes. Both require a toe cap tested to a 200-joule impact and 15 kN compression. The material may be steel, aluminium or composite in either category, and all three pass identical tests. Is S1P enough for warehouse work? Usually, where the floor is dry indoor concrete and the risk assessment allows it. Warehouses with outdoor yards, loading bays or wash-down areas commonly specify S3 instead. Confirm with your employer rather than assuming. What does S3L or S3S mean? They are S3 with a non-metallic penetration-resistant insert. L indicates the insert was tested with a 4.5 mm point, S with a finer 3 mm point. The protection package is otherwise identical to S3. The Honest Verdict The S1P versus S3 decision is settled by two questions rather than by build quality or price: does water reach your feet, and is the ground loose or uneven. Answer yes to either and S3 is the specification, with S7 worth considering if the wet is sustained rather than occasional. Answer no to both and S1P gives you the same certified impact and puncture protection in a lighter, cooler shoe. What should never settle it is preference. Comfort, styling and weight are real considerations, but they sit underneath the category requirement, not alongside it. If your risk assessment says S3, the comparison is over before it starts. If Your Workplace Accepts S1P We make S1P footwear and nothing else, so this only applies if the decision tree above pointed you to S1P. If it did, wear a pair through real shifts and tell us honestly how the fit, comfort and durability hold up, including what we got wrong. Xnexz StrideX S1P Safety Shoe See All Ratings, SB to S7
S1P vs S3 Safety Shoes: Which Do You Need?
S1P and S3 safety shoes share four things: a 200-joule toe cap, antistatic properties, an energy-absorbing heel and a puncture-resistant insert. S3 adds two more, upper water resistance and a cleated outsole. That is the entire difference, and those two additions are what decide which one your job needs. This is a decision, not a ranking. S3 is not a better version of S1P for every worker, and paying more for it will not help you if your floor is dry indoor concrete. Below is the comparison, then a straight decision tree that takes about a minute to work through. The Short Answer Choose S1P for dry indoor work with sharp debris underfoot. Choose S3 for wet ground, outdoor work or uneven terrain. If any part of your shift happens outside or on wet flooring, S3 is the correct specification. S1P vs S3 Safety Shoes: The Difference in One Table Feature S1P S3 200 J toe cap Yes Yes Closed seat region Yes Yes Antistatic (A) Yes Yes Energy-absorbing heel (E) Yes Yes Puncture-resistant insert Yes Yes Upper water resistance (WPA) No Yes Cleated outsole No Yes Whole-footwear waterproofing (WR) No No, that is S7 Typical environment Dry indoor floors Wet ground, outdoors, mixed terrain Typical pair weight, UK 9 700 to 1,000 g 1,000 to 1,600 g Only two rows differ. Everything above them is identical protection. Because the protective package is otherwise the same, the common assumption that S3 is "safer" is wrong in a specific way. S3 is not more protective against impact or puncture. It is more protective against water and loose ground. If neither of those is present in your work, S3 buys you weight you do not need. The full code set is laid out in our safety shoe ratings explained guide, SB to S7. The Two Differences That Actually Decide It Upper water resistance (WPA) WPA certifies that the upper material resists water penetration and absorption. It replaced the older WRU marking in the 2022 revision of the standard. In practice it rules out open mesh construction and requires a denser leather, coated or membrane-backed upper. What WPA does not mean is waterproof. It tests the upper material, not the shoe as an assembly, so water can still enter at the tongue, the lace holes or the collar. If you need footwear that genuinely keeps water out over a long wet shift, the marking you want is WR, which appears in categories S6 and S7. Buying S3 expecting a waterproof shoe is the most common disappointment in this category. The cleated outsole S3 requires a cleated outsole, meaning defined lugs with channels between them. On mud, wet grass, gravel and loose ground this is what clears material away and keeps the tread biting. Here is the part that surprises people: on a smooth indoor floor, deep cleats can grip worse than a flatter, finely siped pattern, because lugs reduce the contact area between rubber and floor. An aggressive tread looks safer and, on polished warehouse concrete, often is not. There is more on this in our guide to non-slip safety shoes. The Decision Tree: Which One Do You Need? Quick Answer Work through five questions in order. A yes to any of the first three means S3 or higher. Only if all three are no does S1P become the right specification, and your employer's risk assessment still overrides the outcome. Does your employer's risk assessment specify a category?Yes: that is your answer. Stop here. A specification of S3 cannot be met with S1P footwear, however well made.No or unsure: ask your supervisor or safety officer in writing, then continue. Does any part of your shift happen outdoors?Yes: choose S3. Loading bays, yards, deliveries, car parks and site walks all count. A UK winter makes an hour outdoors a wet hour.No: continue. Is your floor ever wet, greasy or washed down?Yes: choose S3, or S2 if there is no sharp debris underfoot.No: continue. Is the ground uneven, loose or cluttered?Yes: choose S3, and consider a boot rather than a shoe for ankle support.No: continue. Are there sharp objects on the floor, such as nails, staples, screws or swarf?Yes: S1P is the right specification.No: S1 may be sufficient and usually costs less. If you answered yes at question two, nothing further in this article changes your answer. Buy S3. When S1P Is Enough, and When It Is Not Quick Answer S1P suits dry indoor roles with impact and puncture risk, including warehousing, vehicle workshops, indoor fit-out, facilities and stockroom work. It is not enough for construction, roofing, groundworks, wash-down areas, outdoor depots or cold stores. S1P Is Usually Right For Warehouse picking, packing and dispatch Vehicle workshops and garages, ideally with FO Indoor fit-out, second fix and decorating Facilities, light maintenance and security Retail stockroom and back of house Light assembly and indoor manufacturing You Need S3 or Higher For Construction, groundworks, civils and demolition Roofing, scaffolding and work at height Outdoor yards, depots and loading bays Kitchens and wash-down areas Landscaping, utilities and fieldwork Any role where the ground is wet or broken One judgement worth applying honestly: buy for the harder half of your day. A warehouse operative who spends forty minutes on the loading bay in January is not an indoor worker for footwear purposes. Mixed roles should be specified at the higher requirement, not averaged. Can You Wear S1P Safety Shoes on a Construction Site? Quick Answer Usually not. Most UK construction sites specify S3 as a minimum because of wet ground and uneven terrain, and many principal contractors also require boots for ankle support. S1P may be accepted for dry indoor fit-out or site office work. Site rules are set by the principal contractor and recorded in the site induction, so the answer varies. What does not vary is the consequence of getting it wrong: footwear that does not meet the specified category is refused at the gate, and you lose the shift. Where S1P is sometimes accepted on a construction project, it is typically for second fix, decorating, indoor fit-out, commissioning or site office roles, once the building is watertight and the ground floor is clean. Even then, get it confirmed in writing rather than assuming. Our guide to construction safety shoes in the UK covers what site rules actually require. Does S3 Weigh More and Cost More? Quick Answer Generally yes on both counts. A water-resistant upper and a cleated outsole both add material, so S3 footwear typically weighs 200 to 500 g more per pair than comparable S1P footwear and sits slightly higher in price. The weight difference is real but should not drive the decision. If your work requires S3, a lighter S1P shoe is not a compromise, it is a non-compliant purchase. The useful move is to compare within the category: there are genuinely lighter and heavier S3 options, and that is the choice actually available to you. On price, the gap is usually modest. Both categories span roughly £30 to £120 in the UK, with S3 sitting a little higher for equivalent build quality. Before comparing prices at all, check whether your employer supplies the footwear, since required PPE must be provided free of charge. That is covered in our guide to the UK PPE at Work Regulations. What About S2, S6 and S7? Quick Answer S2 has upper water resistance but no puncture insert. S6 is S2 plus whole-footwear water resistance. S7 is S3 plus whole-footwear water resistance, making it the correct choice for sustained wet outdoor work. Rating Puncture insert Water resistance Cleated outsole S1P Yes None No S2 No Upper only (WPA) No S3 Yes Upper only (WPA) Yes S6 No Whole footwear (WR) No S7 Yes Whole footwear (WR) Yes If you have been choosing between S1P and S3 because your work is genuinely wet rather than merely damp, S7 is probably the specification you actually want. It is the newest of these categories, introduced in the 2022 revision of the standard, and it is still under-stocked by UK retailers compared with S3. The full explanation sits in our EN ISO 20345 certification guide, and the four-way comparison most buyers need is in S1, S1P, S2 or S3 safety shoe rating. Where Xnexz Sits, and When to Buy S3 Instead Quick Answer Xnexz makes S1P-family footwear only, certified in category S1PL FO SR. If your answer to the decision tree above was S3, S6 or S7, we do not make what you need and you should buy from a brand that does. We will be direct about this, because a comparison article written by a manufacturer is worth nothing otherwise. Xnexz produces two trainer-format models certified to EN ISO 20345:2022+A1:2024 in category S1PL FO SR. The Xnexz StrideX S1P safety shoe is the streetwear-influenced option, intended for dry indoor light-duty work where an employer accepts S1P. What that means for this comparison.

Safety Shoe Ratings Explained: SB to S7 (UK)
Safety shoe ratings are category codes under EN ISO 20345, running from SB up to S7. Every code starts from the same base, a toe cap tested to a 200-joule impact, and each higher rating adds a specific tested property on top. This page lists all of them in one table, then explains each code in plain English. The current standard is EN ISO 20345:2022, published with an amendment as EN ISO 20345:2022+A1:2024. It introduced S6 and S7, retired the old SRA, SRB and SRC slip markings, and split puncture resistance into P, PL and PS. The Short Answer SB is a toe cap alone. S1 adds a closed heel, antistatic properties and an energy-absorbing heel. S1P adds a puncture-resistant insert. S2 adds upper water resistance. S3 combines both plus a cleated outsole. S4 and S5 are moulded footwear. S6 and S7 add whole-footwear water resistance. The Complete Safety Shoe Ratings Table, SB to S7 Rating Class What it includes Typical use SB I or II Basic requirements only: 200 J toe cap. Heel region may be open. Rarely accepted as workplace PPE on its own S1 I SB + closed seat region + antistatic (A) + energy absorption of the seat region (E) Dry indoor work, no sharp underfoot hazard S1P I S1 + penetration resistance, metallic insert (P) Dry indoor work with nails, staples or swarf S1PL I S1 + penetration resistance, non-metallic insert tested at 4.5 mm (PL) As S1P, lighter and more flexible underfoot S1PS I S1 + penetration resistance, non-metallic insert tested at 3 mm (PS) As S1PL, plus finer sharp objects S2 I S1 + water penetration and absorption resistance of the upper (WPA) Damp indoor work, wash-down edges, kitchens S3 I S2 + penetration resistance (P) + cleated outsole Construction, groundworks, outdoor and mixed sites S3L / S3S I As S3, with a non-metallic insert tested at 4.5 mm (L) or 3 mm (S) As S3, with a lighter insert S4 II All-rubber or all-polymeric + closed seat region + antistatic + energy absorption Food production, agriculture, wash-down S5 II S4 + penetration resistance + cleated outsole Wet, muddy or heavily soiled environments S5L / S5S II As S5, with a non-metallic insert (L = 4.5 mm, S = 3 mm) As S5, with a lighter insert S6 I S2 + whole-footwear water resistance (WR) Prolonged wet work needing a leather or fabric upper S7 I S3 + whole-footwear water resistance (WR) Wet outdoor sites with sharp underfoot hazards S7L / S7S I As S7, with a non-metallic insert (L = 4.5 mm, S = 3 mm) As S7, with a lighter insert What Every Certified Safety Shoe Must Do Quick Answer Every rating from SB upwards requires a toe cap withstanding a 200-joule impact and 15 kN compression, plus slip resistance tested on ceramic tile with a soap solution, material innocuousness, ergonomic performance, and defined durability of the upper and outsole. These are the basic requirements, and they are what the letter S means. A shoe without them is not safety footwear regardless of how it is described. Toe cap: 200 J impact and 15 kN compression. Roughly a 20 kg object falling one metre, and around 1.5 tonnes of slow crushing load. Slip resistance: mandatory since the 2022 revision, tested on ceramic tile with a sodium lauryl sulphate solution. Construction and materials: tear strength, flexing resistance, interlayer bond strength, and limits on substances such as chromium VI in leather. Ergonomics: the footwear must be wearable and functional, not simply protective. Two related standards are often confused with this one. EN ISO 20347 covers occupational footwear with no toe cap at all, coded OB and O1 to O7. EN ISO 20346 covers protective footwear with a lower 100-joule toe cap, coded PB and P1 to P5. Only EN ISO 20345 gives you the 200-joule toe cap, and only its codes begin with S. What Each Rating Adds, Step by Step SB: the baseline SB means the footwear meets the basic requirements and nothing else. The heel region may be open, there is no antistatic requirement and no puncture protection. Most UK employers do not accept SB alone, because a workplace risk assessment that identifies impact risk usually identifies other risks alongside it. S1: closed heel, antistatic, energy-absorbing heel S1 adds three things to SB. A closed seat region, which rules out open-backed constructions. Antistatic properties, meaning electrical resistance between 0.1 MΩ and 1,000 MΩ so static charge drains gradually. And energy absorption of the seat region, at least 20 joules, which cushions heel strike on hard floors. Note what antistatic is not. It is not electrical insulation and must never be relied on as protection against contact with live equipment. S1P, S1PL and S1PS: adding puncture protection The P family adds a penetration-resistant insert between the outsole and the footbed, resisting at least 1,100 N. The suffix tells you which insert and which test point: Code Insert Test point Effect P Metallic plate 4.5 mm Rigid, partial footbed coverage, heavier PL Non-metallic textile 4.5 mm Flexible, near-full coverage, lighter PS Non-metallic textile 3 mm As PL, plus thinner sharp objects PS is the stricter of the two non-metallic routes, because a fine 3 mm point is harder for a woven insert to stop than a blunter 4.5 mm one. All three certify the same 1,100 N force. The full picture sits in our complete S1P safety shoes guide. S2: upper water resistance S2 takes S1 and adds water penetration and absorption resistance of the upper, marked WPA. This replaced the older WRU marking in the 2022 revision. Importantly, S2 does not include a puncture-resistant insert, so S2 is not simply a step up from S1P. They protect against different things. S3: the common site specification S3 combines S2 with penetration resistance and adds a cleated outsole. This is the minimum most UK construction sites specify, because it covers wet ground, sharp debris and uneven terrain in one package. S3L and S3S are the same rating with a non-metallic insert. S4 and S5: moulded Class II footwear S4 and S5 apply only to all-rubber or all-polymeric moulded footwear, which in practice means wellingtons and food-industry boots. S4 covers a closed seat region, antistatic properties and energy absorption. S5 adds penetration resistance and a cleated outsole. You will never find an S5 trainer, because the category requires a moulded one-piece construction. S6 and S7: the new water-resistance categories These arrived with the 2022 revision and are the most useful addition for UK conditions. S6 is S2 plus whole-footwear water resistance, marked WR. S7 is S3 plus WR. Before 2022, WR had to be added to S2 or S3 as a separate marking, and many buyers missed it. Now it has its own category. The distinction that matters: WPA tests the upper material, while WR tests the whole shoe as an assembly. If you need footwear that keeps water out in sustained wet conditions, look for WR, S6 or S7, not S2 or S3. What the Additional Marking Codes Mean Quick Answer Beyond the category code, individual letters certify specific tested properties: A for antistatic, E for energy absorption, P for penetration resistance, WPA and WR for water resistance, SR for additional slip resistance, FO for fuel oil resistance, and several specialist markings. Code What it certifies A Antistatic: electrical resistance between 0.1 MΩ and 1,000 MΩ E Energy absorption of the seat region, at least 20 J P / PL / PS Penetration resistance of at least 1,100 N WPA Water penetration and absorption resistance of the upper (replaced WRU) WR Water resistance of the whole footwear SR Additional slip resistance, tested on ceramic tile with glycerine FO Outsole resistant to fuel oil. Optional since 2022, previously mandatory for S1 to S3 HRO Outsole resistant to hot contact, tested at 300 °C for 60 seconds HI Heat insulation of the outsole complex CI Cold insulation of the outsole complex M Metatarsal protection, tested at 100 J AN Ankle protection CR Cut resistance of the upper SC Scuff cap abrasion resistance LG Ladder grip, tested against a ladder rung A full label therefore reads something like "EN ISO 20345:2022 S3L SR HRO", which tells you the standard, the version, the category, the insert type and two additional tested properties. Our EN ISO 20345 certification guide works through every code in more depth. Which Rating Does Your Job Need? Quick Answer Dry indoor work with sharp debris underfoot usually needs S1P. Damp indoor work needs S2. Outdoor, wet or mixed terrain needs S3 or S7. Wash-down and standing water need S5. Your employer's risk assessment sets the actual requirement. Environment Usual minimum Why Warehouse and distribution S1P Dry concrete, impact risk, banding staples underfoot Vehicle workshop and garage S1P with FO Dry floors, dropped tools, oil contact on the outsole Indoor fit-out and decorating S1P Dry interiors, nails and screws on the floor Commercial kitchen S2 or S3, SR preferred Standing water, grease, frequent wash-down Healthcare and clinical support S1 or S1P per policy Sharps risk, wipe-clean requirement, long shifts Construction and groundworks S3 or S7, often boots Wet ground, uneven terrain, penetration risk Working at height and ladder use S3 minimum, LG where relevant Rung grip, ankle stability, weather exposure Food production and wash-down S4 or S5 Constant water and cleaning chemicals Treat this table as a conversation starter with your safety officer, not a substitute for one. Conditions differ between two sites with the same name on the door, and UK law makes the workplace risk assessment decisive. Employers must provide required PPE free of charge, which is covered in our guide to the UK PPE at Work Regulations. For a direct four-way comparison of the most common codes, see S1, S1P, S2 or S3 safety shoe rating. Are Safety Boot Ratings Different From Safety Shoe Ratings? Quick Answer No. Safety boot ratings use the identical SB to S7 codes under the same standard. A boot and a shoe carrying the same rating have passed the same tests. The difference is coverage and ankle support, neither of which is part of the category code. This causes constant confusion, so it is worth being direct. There is no separate boot standard. An S3 boot and an S3 shoe both have a 200-joule toe cap, upper water resistance, a puncture-resistant insert and a cleated outsole. What the boot adds is height, which brings ankle support, better debris exclusion and more splash protection. If ankle protection is specifically required, look for the AN marking rather than assuming a boot provides it. AN is a tested property with its own criteria, and plenty of boots do not carry it. What Changed From the 2011 Standard? Quick Answer The 2022 revision made slip resistance a basic requirement and retired SRA, SRB and SRC. It renamed WRU to WPA, made fuel oil resistance optional, split puncture resistance into P, PL and PS, and added the S6, S7, SC and LG codes. Area EN ISO 20345:2011 EN ISO 20345:2022 Slip resistance Optional, marked SRA, SRB or SRC Mandatory basic requirement. Optional glycerine test marked SR Upper water resistance WRU WPA Fuel oil resistance Mandatory in S1, S2, S3 Optional, marked FO when claimed Puncture resistance P only P, PL and PS Waterproof categories WR added to S2 or S3 New categories S6 and S7 New markings None SC (scuff cap abrasion), LG (ladder grip) Certificates issued under the 2011 version stay valid until they expire, so both vocabularies are still in circulation. If a 2026 listing advertises SRC, either the stock predates the revision or the product copy has not been updated. Neither means the shoe grips badly, but it does tell you something about how carefully the seller maintains its information. How to Check a Shoe's Rating Quick Answer Look for the permanent marking stamped inside the tongue, collar or quarter lining. It must show the standard and year, the category code, the size, the manufacturer and the date of manufacture. The label overrides the product listing. Find the permanent marking. Inside the tongue or collar, not on a swing tag or the box. Read the standard and year. EN ISO 20345:2022 or 2022+A1:2024 is current. Check the category against the listing. If the page says S3 and the label says S1P, the label is correct. Ask for the certificate. Safety footwear is Category II PPE, so an independent body must carry out a type examination and issue a certificate naming itself and its four-digit number. A legitimate seller can produce it, along with the Declaration of Conformity. Frequently Asked Questions What is the highest safety shoe rating? S7 is the highest rating for Class I footwear, combining S3 with whole-footwear water resistance. S5 is the highest for Class II moulded footwear. Neither is universally best, because they suit different constructions and different work. What is the difference between S1P and S3? Both include a 200-joule toe cap, antistatic properties, an energy-absorbing heel and a puncture-resistant insert. S3 adds upper water resistance and a cleated outsole, which is why it is the usual minimum for outdoor and construction work while S1P is a dry indoor specification. Is S2 better than S1P? Neither is better overall. S1P has a puncture-resistant insert and no water resistance. S2 has upper water resistance and no puncture-resistant insert. Choose based on whether your main hazard is sharp debris or moisture. What does the L or S mean after a rating? They indicate a non-metallic penetration-resistant insert. L means it was tested with a 4.5 mm point, S means it was tested with a finer 3 mm point. So S3S has the same protection package as S3, with a non-metallic insert tested against thinner objects. Are SRA, SRB and SRC still used? Not under the current standard. Slip resistance became a mandatory basic requirement in the 2022 revision, so those three markings were retired. The optional SR marking now indicates a further test using glycerine on ceramic tile. Do safety shoe ratings tell you the toe cap material? No. The rating specifies the protection level, not the material. A 200-joule cap may be steel, aluminium or composite, and all three pass identical impact and compression tests. Only the P, PL and PS codes tell you anything about material, and they refer to the sole insert rather than the toe. Which safety shoe rating do most UK warehouses require? S1P is the most common minimum for dry indoor warehouse floors, covering impact risk, static and sharp debris underfoot. Sites with yard work, loading bays or wash-down areas often specify S3 instead. Always confirm with your employer. Using This Page Safety shoe ratings are a closed list, not a marketing scale. Every property a shoe has must be earned through a test and declared with a code, so if water resistance, heat resistance or metatarsal protection is not in the marking, the shoe has not been tested for it. That principle makes the table at the top of this page more reliable than any product description. For transparency: we make safety footwear ourselves. Xnexz produces trainer-format shoes certified in category S1PL FO SR, which is a light-duty specification intended for dry indoor settings where an employer accepts S1P. We do not make S3, S6, S7, S4 or S5 footwear, and we do not make boots, so for wet, outdoor or specialist work the right answer is another brand.

These are the basic requirements, and they are what the letter S means. A shoe without them is not safety footwear regardless of how it is described. Toe cap: 200 J impact and 15 kN compression. Roughly a 20 kg object falling one metre, and around 1.5 tonnes of slow crushing load. Slip resistance: mandatory since the 2022 revision, tested on ceramic tile with a sodium lauryl sulphate solution. Construction and materials: tear strength, flexing resistance, interlayer bond strength, and limits on substances such as chromium VI in leather. Ergonomics: the footwear must be wearable and functional, not simply protective. Two related standards are often confused with this one. EN ISO 20347 covers occupational footwear with no toe cap at all, coded OB and O1 to O7. EN ISO 20346 covers protective footwear with a lower 100-joule toe cap, coded PB and P1 to P5. Only EN ISO 20345 gives you the 200-joule toe cap, and only its codes begin with S. What Each Rating Adds, Step by Step SB: the baseline SB means the footwear meets the basic requirements and nothing else. The heel region may be open, there is no antistatic requirement and no puncture protection. Most UK employers do not accept SB alone, because a workplace risk assessment that identifies impact risk usually identifies other risks alongside it. S1: closed heel, antistatic, energy-absorbing heel S1 adds three things to SB. A closed seat region, which rules out open-backed constructions. Antistatic properties, meaning electrical resistance between 0.1 MΩ and 1,000 MΩ so static charge drains gradually. And energy absorption of the seat region, at least 20 joules, which cushions heel strike on hard floors. Note what antistatic is not. It is not electrical insulation and must never be relied on as protection against contact with live equipment. S1P, S1PL and S1PS: adding puncture protection The P family adds a penetration-resistant insert between the outsole and the footbed, resisting at least 1,100 N. The suffix tells you which insert and which test point: Code Insert Test point Effect P Metallic plate 4.5 mm Rigid, partial footbed coverage, heavier PL Non-metallic textile 4.5 mm Flexible, near-full coverage, lighter PS Non-metallic textile 3 mm As PL, plus thinner sharp objects PS is the stricter of the two non-metallic routes, because a fine 3 mm point is harder for a woven insert to stop than a blunter 4.5 mm one. All three certify the same 1,100 N force. The full picture sits in our complete S1P safety shoes guide. S2: upper water resistance S2 takes S1 and adds water penetration and absorption resistance of the upper, marked WPA. This replaced the older WRU marking in the 2022 revision. Importantly, S2 does not include a puncture-resistant insert, so S2 is not simply a step up from S1P. They protect against different things. S3: the common site specification S3 combines S2 with penetration resistance and adds a cleated outsole. This is the minimum most UK construction sites specify, because it covers wet ground, sharp debris and uneven terrain in one package. S3L and S3S are the same rating with a non-metallic insert. S4 and S5: moulded Class II footwear S4 and S5 apply only to all-rubber or all-polymeric moulded footwear, which in practice means wellingtons and food-industry boots. S4 covers a closed seat region, antistatic properties and energy absorption. S5 adds penetration resistance and a cleated outsole. You will never find an S5 trainer, because the category requires a moulded one-piece construction. S6 and S7: the new water-resistance categories These arrived with the 2022 revision and are the most useful addition for UK conditions. S6 is S2 plus whole-footwear water resistance, marked WR. S7 is S3 plus WR. Before 2022, WR had to be added to S2 or S3 as a separate marking, and many buyers missed it. Now it has its own category. The distinction that matters: WPA tests the upper material, while WR tests the whole shoe as an assembly. If you need footwear that keeps water out in sustained wet conditions, look for WR, S6 or S7, not S2 or S3. What the Additional Marking Codes Mean Quick Answer Beyond the category code, individual letters certify specific tested properties: A for antistatic, E for energy absorption, P for penetration resistance, WPA and WR for water resistance, SR for additional slip resistance, FO for fuel oil resistance, and several specialist markings. Code What it certifies A Antistatic: electrical resistance between 0.1 MΩ and 1,000 MΩ E Energy absorption of the seat region, at least 20 J P / PL / PS Penetration resistance of at least 1,100 N WPA Water penetration and absorption resistance of the upper (replaced WRU) WR Water resistance of the whole footwear SR Additional slip resistance, tested on ceramic tile with glycerine FO Outsole resistant to fuel oil. Optional since 2022, previously mandatory for S1 to S3 HRO Outsole resistant to hot contact, tested at 300 °C for 60 seconds HI Heat insulation of the outsole complex CI Cold insulation of the outsole complex M Metatarsal protection, tested at 100 J AN Ankle protection CR Cut resistance of the upper SC Scuff cap abrasion resistance LG Ladder grip, tested against a ladder rung A full label therefore reads something like "EN ISO 20345:2022 S3L SR HRO", which tells you the standard, the version, the category, the insert type and two additional tested properties. Our EN ISO 20345 certification guide works through every code in more depth. Which Rating Does Your Job Need? Quick Answer Dry indoor work with sharp debris underfoot usually needs S1P. Damp indoor work needs S2. Outdoor, wet or mixed terrain needs S3 or S7. Wash-down and standing water need S5. Your employer's risk assessment sets the actual requirement. Environment Usual minimum Why Warehouse and distribution S1P Dry concrete, impact risk, banding staples underfoot Vehicle workshop and garage S1P with FO Dry floors, dropped tools, oil contact on the outsole Indoor fit-out and decorating S1P Dry interiors, nails and screws on the floor Commercial kitchen S2 or S3, SR preferred Standing water, grease, frequent wash-down Healthcare and clinical support S1 or S1P per policy Sharps risk, wipe-clean requirement, long shifts Construction and groundworks S3 or S7, often boots Wet ground, uneven terrain, penetration risk Working at height and ladder use S3 minimum, LG where relevant Rung grip, ankle stability, weather exposure Food production and wash-down S4 or S5 Constant water and cleaning chemicals Treat this table as a conversation starter with your safety officer, not a substitute for one. Conditions differ between two sites with the same name on the door, and UK law makes the workplace risk assessment decisive. Employers must provide required PPE free of charge, which is covered in our guide to the UK PPE at Work Regulations. For a direct four-way comparison of the most common codes, see S1, S1P, S2 or S3 safety shoe rating. Are Safety Boot Ratings Different From Safety Shoe Ratings? Quick Answer No. Safety boot ratings use the identical SB to S7 codes under the same standard. A boot and a shoe carrying the same rating have passed the same tests. The difference is coverage and ankle support, neither of which is part of the category code. This causes constant confusion, so it is worth being direct. There is no separate boot standard. An S3 boot and an S3 shoe both have a 200-joule toe cap, upper water resistance, a puncture-resistant insert and a cleated outsole. What the boot adds is height, which brings ankle support, better debris exclusion and more splash protection. If ankle protection is specifically required, look for the AN marking rather than assuming a boot provides it. AN is a tested property with its own criteria, and plenty of boots do not carry it. What Changed From the 2011 Standard? Quick Answer The 2022 revision made slip resistance a basic requirement and retired SRA, SRB and SRC. It renamed WRU to WPA, made fuel oil resistance optional, split puncture resistance into P, PL and PS, and added the S6, S7, SC and LG codes. Area EN ISO 20345:2011 EN ISO 20345:2022 Slip resistance Optional, marked SRA, SRB or SRC Mandatory basic requirement. Optional glycerine test marked SR Upper water resistance WRU WPA Fuel oil resistance Mandatory in S1, S2, S3 Optional, marked FO when claimed Puncture resistance P only P, PL and PS Waterproof categories WR added to S2 or S3 New categories S6 and S7 New markings None SC (scuff cap abrasion), LG (ladder grip) Certificates issued under the 2011 version stay valid until they expire, so both vocabularies are still in circulation. If a 2026 listing advertises SRC, either the stock predates the revision or the product copy has not been updated. Neither means the shoe grips badly, but it does tell you something about how carefully the seller maintains its information. How to Check a Shoe's Rating Quick Answer Look for the permanent marking stamped inside the tongue, collar or quarter lining. It must show the standard and year, the category code, the size, the manufacturer and the date of manufacture. The label overrides the product listing. Find the permanent marking. Inside the tongue or collar, not on a swing tag or the box. Read the standard and year. EN ISO 20345:2022 or 2022+A1:2024 is current. Check the category against the listing. If the page says S3 and the label says S1P, the label is correct. Ask for the certificate. Safety footwear is Category II PPE, so an independent body must carry out a type examination and issue a certificate naming itself and its four-digit number. A legitimate seller can produce it, along with the Declaration of Conformity. Frequently Asked Questions What is the highest safety shoe rating? S7 is the highest rating for Class I footwear, combining S3 with whole-footwear water resistance. S5 is the highest for Class II moulded footwear. Neither is universally best, because they suit different constructions and different work. What is the difference between S1P and S3? Both include a 200-joule toe cap, antistatic properties, an energy-absorbing heel and a puncture-resistant insert. S3 adds upper water resistance and a cleated outsole, which is why it is the usual minimum for outdoor and construction work while S1P is a dry indoor specification. Is S2 better than S1P? Neither is better overall. S1P has a puncture-resistant insert and no water resistance. S2 has upper water resistance and no puncture-resistant insert. Choose based on whether your main hazard is sharp debris or moisture. What does the L or S mean after a rating? They indicate a non-metallic penetration-resistant insert. L means it was tested with a 4.5 mm point, S means it was tested with a finer 3 mm point. So S3S has the same protection package as S3, with a non-metallic insert tested against thinner objects. Are SRA, SRB and SRC still used? Not under the current standard. Slip resistance became a mandatory basic requirement in the 2022 revision, so those three markings were retired. The optional SR marking now indicates a further test using glycerine on ceramic tile. Do safety shoe ratings tell you the toe cap material? No. The rating specifies the protection level, not the material. A 200-joule cap may be steel, aluminium or composite, and all three pass identical impact and compression tests. Only the P, PL and PS codes tell you anything about material, and they refer to the sole insert rather than the toe. Which safety shoe rating do most UK warehouses require? S1P is the most common minimum for dry indoor warehouse floors, covering impact risk, static and sharp debris underfoot. Sites with yard work, loading bays or wash-down areas often specify S3 instead. Always confirm with your employer. Using This Page Safety shoe ratings are a closed list, not a marketing scale. Every property a shoe has must be earned through a test and declared with a code, so if water resistance, heat resistance or metatarsal protection is not in the marking, the shoe has not been tested for it. That principle makes the table at the top of this page more reliable than any product description. For transparency: we make safety footwear ourselves. Xnexz produces trainer-format shoes certified in category S1PL FO SR, which is a light-duty specification intended for dry indoor settings where an employer accepts S1P. We do not make S3, S6, S7, S4 or S5 footwear, and we do not make boots, so for wet, outdoor or specialist work the right answer is another brand. We have set out that position in full in the complete UK safety shoes buyer's guide. Continue Reading EN ISO 20345 certification guide: the standard behind every rating on this page.
