How safety footwear is made and certified
Safety shoes and boots are built like work footwear, with two protective parts added. A toe cap, of steel, aluminium or a composite, is set between the upper and the lining at the toe before lasting. A penetration-resistant insert, either a steel plate or a layered textile, sits between the insole and the outsole. Most Indian safety footwear has a leather upper and a direct-injected PU or PU/rubber sole, which bonds to the upper in the mould without adhesive. Exports of leather-upper footwear with a protective metal toe cap (HS 640340) were US$126.29 million in FY2025-26 (Department of Commerce, TradeStat, provisional).
The difference from other footwear is that the product is certified before it is made in volume:
- EU. Safety footwear is personal protective equipment under Regulation (EU) 2016/425, normally Category II. A notified body examines and tests the model and issues an EU type-examination certificate. The standard used is EN ISO 20345:2022, the European adoption of ISO 20345:2021, which replaced the 2011 edition. A safety shoe's toe cap must resist a 200 J impact and a 15 kN compression load.
- Great Britain. The same regulation applies as retained law; see UKCA and CE marking for which marks are accepted.
- US. OSHA's foot protection rule, 29 CFR 1910.136, requires protective footwear to meet ASTM F2413 (with test methods in ASTM F2412) or an equivalent. The current edition is F2413-24. Compliance is shown by test reports, not by a notified body certificate.
The certificate covers one model with one construction. Changing the toe cap supplier, the sole compound or the insert can take the shoe outside the certificate, even if it looks the same.
What we check on safety footwear
| Check | How it is checked | What fails |
|---|---|---|
| Certificate and model | Certificate read for model name, protection class, size range, manufacturer and expiry; compared with the shoe and the order | Model or sizes not on the certificate; certificate expired or for another factory |
| Marking in the shoe | Tongue or lining label checked for CE or UKCA marking, standard number, protection class (for example S1, S3), size, manufacturer and date of manufacture | Missing or illegible marking; class different from the certificate |
| Toe cap | Toe pressed on every sampled shoe; steel caps found with a magnet; one sacrificial pair cut open where agreed | Toe cap missing, wrong type, or loose and shifting |
| Penetration-resistant insert | Insert type checked against the marking (steel or non-metal); cut-section of a sacrificial shoe where agreed | Insert missing in a class that requires it; wrong insert type |
| Sole and bond | Sole compound and tread against the sample; edge bond pressed and flexed; heel and toe checked for voids from injection | Bond gaps, voids or bubbles in the sole, wrong tread pattern |
| User information | Instructions in the languages of the destination market checked in the box; declaration of conformity or its web address present | Missing or wrong-language instructions |
| Size and pairing | Size marks against boxes; inside length; both shoes same class marking | Mixed sizes; one shoe with a different class label |
| Workmanship | Stitching, lacing hardware, collar padding, scuff cap | Broken stitches, sharp eyelets, collar seams rubbing |
Common safety shoe and boot defects and how they are classed
| Defect | Typical cause | Class |
|---|---|---|
| Toe cap or penetration insert missing | Assembly error on the lasting line | Critical |
| Marking does not match the certificate | Wrong labels, or a model change not recertified | Critical |
| Model or size not covered by the certificate | Certificate for another variant or size range | Critical |
| Sole separating or voids in the injected sole | Mould temperature, contaminated upper surface | Major |
| Toe cap edge felt through the lining | Missing or thin toe cap padding | Major |
| Instructions missing or in the wrong language | Generic leaflet used | Major |
| Scuffs and adhesive marks on uppers | Handling, careless finishing | Minor |
A safety shoe that differs from its certified model is not a cosmetic problem: it may not protect the wearer and cannot lawfully carry the CE marking. Your defect list decides the final class.
What the inspector verifies and what goes to the lab
The protective claims of a safety shoe are proved by destructive tests on special rigs: toe cap impact and compression, penetration resistance, slip resistance, electrical resistance for antistatic claims, heat resistance of the sole, and water resistance for classes that include it. The 2022 edition of EN ISO 20345 also changed some markings, for example splitting penetration-resistant inserts into P (steel) and PL or PS (non-metal), and adding classes S6 and S7. An inspector does not run these tests.
What the inspector can do is make sure the goods are the goods that were tested: the same model, the same toe cap, the same insert, the same sole, the same markings. For a new supplier or a large order, pairs can be pulled at random, sealed and sent to an ISO/IEC 17025-accredited lab of your choice through lab testing coordination. Chromium VI in leather linings and uppers is also a lab test; see chromium VI in leather.
Packing, transit and your purchase order
Safety boots are heavy, so master cartons hold fewer pairs and must be strong enough to stack. Steel toe caps can rust if boots are packed damp, which shows as stains on the lining. The inspector checks carton weight and strength, box labels with the model and size, and that instructions are inside each box, not loose in the carton.
Put these in your purchase order:
- Model, standard and protection class (for example EN ISO 20345:2022 S3, or ASTM F2413 with the required ratings).
- Copy of the EU type-examination certificate or test reports, with the size range covered.
- Toe cap and insert type and supplier; sole compound.
- Marking layout inside the shoe and on the box.
- Languages for user instructions; declaration of conformity format.
- Lab tests you want on pairs pulled from the lot, if any.
