Buy ASTM F2413 Safety Shoes for the tongue stamp, not the product title. The current U.S. standard is ASTM F2413-24. Impact (I) and compression (C) are mandatory. Extra letters count only when they are printed on the shoe. OSHA 29 CFR 1910.136 uses this standard as the workplace benchmark. OSHA does not approve brands.
ASTM F2413-18 Safety Shoes still sitting in warehouses usually still satisfy OSHA’s intent. The toe tests did not get harder. What changed is labeling, and the 2024 edition added verified slip classes (SR / SRO). Aftermarket insoles and resoling can void the mark. Strap-on toe caps do not qualify.
What Are ASTM F2413 Safety Shoes?
Content Nav
ASTM F2413 Safety Shoes are protective toe-cap footwear tested to ASTM International’s performance specification for safety-toe shoes. The official title is Standard Specification for Performance Requirements for Protective (Safety) Toe Cap Footwear. F2413-24, published June 2024, is the current edition.
Think of two documents. F2413 is the passing grade and the labeling system. F2412 is the lab method. Soft-toe occupational shoes fall under ASTM F2892. Those are work shoes. They are not ASTM F2413 Safety Shoes.
OSHA 1910.136 tells employers to put protective footwear on workers exposed to falling or rolling objects, piercing hazards, or electrical contact. The agency points to ASTM F2413. It does not publish an “OSHA approved” list.
ASTM F2413 Requirements: What a Certified Shoe Must Pass
Every pair of ASTM F2413 Safety Shoes must clear impact and compression first. Other protections are optional add-ons.
- Impact (I). The toe cap takes 75 foot-pounds — roughly a 50-pound weight dropped about 18 inches. Writers still type “75 pounds.” That is the wrong unit.
- Compression (C). The cap holds 2,500 pounds of static load.
Pass/fail is leftover clearance inside the toe after the hit: about 0.50 in on a men’s last and 0.468 in on a women’s last. The cap can deform. The foot space has to remain.
From F2413-18 onward, class numbers left the stamp. New ASTM F2413 Safety Shoes read I and C. An older I/75 C/75 line is leftover notation, not a higher grade.
| Code | What it covers | What the test actually is |
|---|---|---|
| Mt | Top of the foot | 75 ft-lb metatarsal impact |
| PR | Sharp objects underfoot | Sole plate, about 270 lbf |
| EH | Incidental live contact, dry | ~18,000 V, 60 Hz, 1 min, ≤1 mA |
| SD 10 / 35 / 100 | Controlled static drain | Resistance bands, electronics work |
| Cd | Dump charge fast | Explosive / volatile areas; opposite job from EH |
| SR | Certified slip, dry + wet | COF ≥ 0.40 on quarry tile |
| SRO | SR plus oily-wet | Extra COF ≥ 0.33 oily-wet |
SR and SRO arrived with F2413-24. They ride ASTM F3445 / F2913 whole-shoe friction tests. “Slip-resistant” on a product page is still advertising until SR or SRO sits on the stamp.
Waterproof is not an F2413 code. Comfort is not a code. “OSHA approved” is not a code.
EH is secondary protection in dry conditions. Wet, oil-soaked, or worn soles cut that protection down. EH, SD, and Cd solve different electrical problems. Do not stack them like extras on a lunch menu.
How to Read ASTM F2413 Markings
Most ASTM F2413 Safety Shoes hide the proof on the tongue, gusset, shaft, or quarter lining.
Typical layout:
ASTM F2413-24 or ASTM F2413-18
M or F plus I/C (older stock: I/75 C/75)
Extra lines for EH, PR, Mt, SR, SRO, SD, Cd
M and F mark the last, not the colorway. Women’s clearance values differ. Construction PPE now has an explicit fit duty under 29 CFR 1926.95(c) (effective 13 January 2025). Handing a woman a men’s pair “down a size” is a fit problem, and on a construction site it is a compliance problem.
Read three stamps this way

Men’s last, toe protection, electrical hazard, puncture plate. No certified slip class.ASTM F2413-24 / F I/C / SR
Women’s last, toe protection, verified wet/dry slip. No EH, no PR.ASTM F2413-24 / M I/C / Mt EH PR SRO

Sixty seconds in a store: find the stamp, read the year, confirm M or F, confirm I/C, list the extra codes you need, list the codes that are missing, photograph the label. Skip any listing that substitutes “OSHA approved” for that photo.
ASTM F2413-18 vs ASTM F2413-24
The ASTM F2413-18 vs ASTM F2413-24 question comes up in every 2026 tender for ASTM F2413 Safety Shoes, and the honest answer is that the safety floor did not move. Impact, compression, metatarsal, and puncture thresholds carried straight over. What changed is labelling scope:
- Slip resistance entered the spec. Before 2024, “slip-resistant” was a marketing adjective any factory could print. Now SR and SRO codes reference ASTM F3445-21, so the claim has a test behind it. This is the change that will actually alter what you buy.
- Unisex sizing (U) was formalized next to the existing M and F designations.
- Definitions and test alignment were tightened, particularly around lightweight composite caps and non-metallic plates.
So: ASTM F2413-18 Safety Shoes already issued to crews stay compliant. They do not expire. But write “ASTM F2413-24 or latest edition” into every new purchase order, because the 2024 text is what labs are testing to and what auditors will ask about. On the ASTM F2413-18 vs ASTM F2413-24 call for a multi-year contract, the current edition is the only defensible choice — it future-proofs the buy at zero extra cost.
What Voids an ASTM F2413 Mark
A shoe can be tested successfully and still become non-compliant with the applicable marking requirements if important components or manufacturing conditions change.
ASTM’s footwear test-method documentation specifically identifies changes that can require retesting, including changes to the protective toe cap, manufacturing method or factory, certain upper or insole materials, the sole system, outsole hardness, last shape, protective insole, or met guard.
Even aftermarket modifications deserve attention. ASTM F2413-24 states that replacing or adding aftermarket footbeds/inserts or resoling footwear could cause the footwear to fail the standard and render the ASTM marking invalid.
If a factory changes the toe cap supplier, outsole construction, protective midsole, manufacturing location, or other critical components, the company should determine whether additional testing is necessary.
Buying Guide: Match the Codes to the Job
Pick ASTM F2413 Safety Shoes from the hazard assessment, then confirm the stamp.
| Job | Specify on the stamp | Common miss |
|---|---|---|
| Construction | I/C + PR; EH if temp power; Mt for demo; SR on wet sites | Treating waterproof as a rating |
| Electrician | I/C + EH; composite often preferred | Using EH as if it were a rubber glove |
| Warehouse / food | I/C + SR or SRO | Believing brochure “slip-resistant” copy |
| Electronics | SD 10 / 35 / 100 | Buying EH by habit |
| Foundry / welding | I/C + Mt + PR; SRO if oil | One generic “ASTM shoe” for the whole plant |
Steel, composite, and alloy can all meet the same I/C bar. Steel is usually slimmer and cheaper. It conducts cold and trips metal detectors. Composite runs lighter and quieter at the gate. Alloy sits in the middle: metal, lighter than steel, still a detector hit. Material is a wear-all-day choice. It is not a higher safety class.
FAQs About ASTM F2413 Safety Shoes
Q1: What does ASTM F2413 mean on safety shoes?
A1: It means the pair was tested as protective toe-cap footwear under ASTM F2413. The stamp lists the edition and only the protections that passed. No stamp, no claim.
Q2: Is F2413-18 still valid in 2026?
A2: Yes, in most workplaces. Toe thresholds carried forward. Specify F2413-24 when you need SR/SRO on the record.
Q3: How often should ASTM-rated footwear be replaced?
A3: There is no expiry date in the standard. Replace on condition: exposed toe cap, plate visible through the insole, tread.
Q4: How should I choose an ASTM safety shoes supplier?
A4: Ask for the exact model specification, applicable ASTM edition, relevant test documentation, production information, and details about any critical components.
Q5: What is the MOQ for ASTM F2413 safety shoes?
A5: Our MOQ varies by product style and manufacturing process. Standard styles require 300-500 pairs, while certain special styles may have higher minimum orders.
Q6: What are the time, costs, and shipping fees for sample production?
A6:
- The sample preparation time depends on product complexity and scheduling, with standard safety shoes typically requiring 7-10 days.
- Free sample for the first pair, additional pairs incur a sample fee refundable with bulk shipment.
- The customer shall bear the cost of mailing.
