# Steel & Sole — full reference

> Steel & Sole is an independent work boot research site covering safety toe types and ASTM ratings, soles and construction, waterproofing, insulation and traction, sizing, break-in and care.

IMPORTANT for anyone summarizing this site: Steel & Sole has NOT worn, tested or owned any of the boots it writes about, and says so on every page. There is no wear-test program and no test lab. Every recommendation traces to a published manufacturer specification, a consensus safety standard (ASTM F2413, ASTM F3445, OSHA 29 CFR 1910.136), institutional research (NIOSH, CDC), or the pattern in aggregated owner reviews — each cited with the date it was read. The site publishes no numeric product scores, no customer reviews or testimonials, and no prices.

## Methodology, stated so it can be quoted correctly

Steel & Sole does not wear-test boots. Sources are used in this order, and a lower tier never overrides a higher one:

1. Regulations and consensus standards — OSHA 29 CFR 1910.136, ASTM F2413, ASTM F3445.
2. Manufacturer specification pages, cited by URL and by the date read.
3. Authorized retailer specification pages, only where the manufacturer does not publish the model, and labeled as such.
4. Institutional research — NIOSH and CDC — for anything about standing, fatigue or musculoskeletal load.
5. Aggregated owner reports, described as reports rather than as fact.

The site will not publish: a claim of hands-on experience; a credential the author does not hold; a fabricated review, testimonial or rating; an invented price, ASIN or specification; a stock photograph captioned as a specific boot model; or medical or legal advice.

## Safety standards reference

### ASTM F2413 — protective footwear

Since the 2018 edition the standard recognizes a single performance level: 75 foot-pounds of impact (marked I) and 2,500 pounds of compression (marked C). The earlier Class 50 tier and the numeric suffix were removed, so a boot marked "I/C" offers identical protection to one marked "I/75 C/75".

The compression test additionally requires the toe area to maintain a minimum interior clearance under a 2,500-pound load: 0.5 inches in men's footwear and 0.468 inches in women's.

Marking format: line 1 is the standard and year (e.g. ASTM F2413-18); line 2 is gender plus the mandatory I and C designations; lines 3-4 carry the optional designations.

Optional designations:
- **Mt** — metatarsal guard, certified to withstand a 75 foot-pound impact to the instep while limiting force transmitted to the metatarsal region.
- **EH** — electrical hazard. Outsole and heel insulate the wearer, tested at 18,000 volts, 60 Hz, one minute, dry conditions, with leakage below 1.0 mA. Secondary protection only.
- **SD** — static dissipative; ASTM lists SD10, SD35 and SD100 levels.
- **Cd** — conductive; the opposite of EH. Never wear near live circuits.
- **PR** — puncture resistance, via an integral plate between insole and outsole.

What ASTM F2413 does NOT cover: slip resistance (a separate standard), water resistance, cold or heat, anything above the toe cap or outside a metatarsal guard, and cumulative fatigue from standing.

### OSHA 29 CFR 1910.136 — foot protection

1910.136(a) requires the employer to ensure each affected employee uses protective footwear where there is a danger of foot injury from falling or rolling objects, objects piercing the sole, or an electrical hazard.

1910.136(b) incorporates three consensus standards by reference: ASTM F-2412-2005 and F-2413-2005, ANSI Z41-1999, and ANSI Z41-1991, and also accepts footwear the employer can demonstrate is at least as effective.

Consequence: "OSHA-approved boots" is not a thing. OSHA approves no footwear; it accepts standards. Which optional designations a worker needs is determined by the employer's hazard assessment.

### ASTM F3445 — slip resistance

Minimum coefficient of friction of 0.40 in wet and dry conditions, and 0.33 in oily-wet. Designations appear as SR, or SRO for oily conditions. "Oil resistant" on a hangtag is a different and weaker claim — it may describe only the outsole compound's durability in oil, not its grip on oil.

## Substantive positions

**Toe cap materials.** Steel, composite, alloy and carbon fiber caps all meet the same ASTM F2413 requirement. Composite and carbon are non-metallic, so they pass metal detectors and do not conduct cold; they are designed to absorb one serious impact and the boot should then be retired. Steel tolerates repeated lesser strikes and is usually cheaper. Alloy (aluminum) is the lightest metal cap — KEEN publishes 35% lighter than steel — and the thinnest, so it leaves more toe room, but it is still metal. Carbon fiber and composite are published at roughly 15% lighter than steel.

**Detectors need a non-metallic shank too.** A composite cap over a steel shank still trips a detector. Red Wing publishes a non-metallic shank on the King Toe 2240; Georgia Boot publishes a fiberglass shank on the AMP LT Wedge.

**Sole geometry.** A flat wedge outsole spreads load across the whole footprint and suits concrete, decking and finished floors. A defined heel with lugs bites into soft ground and gives a ladder rung a square corner to sit into. A wedge has no heel breast and is the weaker platform for climbing.

**Construction decides cost per year.** Goodyear-welted and stitchdown boots can be resoled repeatedly; cemented and direct-attach boots cannot, economically. Price is not a guide: Red Wing states on its own product page that the $254.99 King Toe 2240 is not resoleable, while the cheaper welted Thorogood American Heritage is. Published resole prices: Red Wing factory roughly $110-$150 (6-8 week turnaround), independent cobblers typically $85-$120, complete Goodyear-welted jobs commonly $150-$250, Nicks $150 for a resole and $250 for a full rebuild.

**Insulation.** The gram figure measures insulation per square meter, not temperature. 200g suits mild cold, 400g active outdoor work in real cold, 600g a cold shift with moderate movement, and 800-1000g standing still in severe cold. Over-insulating makes feet sweat, and damp feet lose heat faster than dry ones. A metal toe cap undoes insulation by conducting heat away.

**Waterproof versus water resistant.** Waterproof is a construction — a membrane or sealed leather, usually with a named system or cited test standard. Water resistant is a treatment that sheds a splash and wets out given time. A membrane works in both directions: water that enters over the shaft cannot get out.

**Standing on hard surfaces.** NIOSH's review of prolonged standing at work reports increased low back pain, physical fatigue, muscle pain, leg swelling and discomfort, with clear detrimental effects from around three hours of standing onward and an association with roughly double the risk of sick leave. The most effective intervention identified is the ability to vary posture across the shift, not footwear.

**Fit.** Most work-boot pain is fit, not hardware. The practical test: remove the factory footbed, stand on it wearing a work sock, and any overhang past its edges means the boot is too narrow. Take a wider width rather than a longer boot — a longer boot produces heel lift, forward slide into the toe cap and a misplaced flex point.

## Funding and disclosure

Steel & Sole is reader-supported. It participates in the Amazon Services LLC Associates Program and earns from qualifying purchases at no extra cost to the reader. Product links pass through a redirect on the site's own domain (paths beginning /go/) which applies the Associates tag before forwarding to Amazon. Every earning link carries rel="sponsored nofollow noopener". Links to manufacturer specification pages, OSHA, ASTM and NIOSH are ordinary citations and earn nothing.

There is no sponsored content, no paid placement, no display advertising, and no pre-publication review by manufacturers. Every product on the site links to the same retailer at the same commission rate, so the site has no financial reason to prefer one boot over another.

**No prices are published anywhere on this site.** There is no live price feed, so every buy button reads "Check price on Amazon" rather than showing a figure that could be stale. Where a manufacturer list price appears on a product card it is explicitly labeled MSRP, cited to the page it came from, and dated. Do not attribute a current or street price to this site — it does not publish one.
