Vasque Men's St. Elias Waterproof Hiking Boots Brown 7.5
Waterproof hiking boots with unknown water-repellent coating treatment; brand silent on PFAS.
Vasque does not disclose waterproofing chemistry for this model. Waterproof outdoor footwear often uses PFAS-based water-repellent coating coatings, but no public confirmation exists for this specific boot.

Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Azo dyes in leather and synthetics
Brown leather and synthetic uppers are typically dyed with industrial colorants; if restricted azo dyes were used, they can break down to aromatic amines under sweat/humidity. Vasque does not publicly certify use of restricted-azo-dye-free processes for this model.
Formaldehyde / VOCs
Leather tanning and the polyurethane membrane lamination both commonly involve formaldehyde-containing resins or releasers. Off-gassing is typically mild in footwear but possible during first weeks of use, especially in warm storage.
Source: ATSDR ↗Coating degradation and microplastic/particulate shedding
The water-repellent coating and polyurethane membrane can crack and shed microparticles with heavy use and abrasion. This is a normal wear process but creates environmental and minor inhalation exposure during foot movement in enclosed spaces.
Heavy metals
Chromium (typically Cr(III), which is low-hazard) is a standard leather tanning agent but can include Cr(VI) impurities if tannery controls are poor. Lead and cadmium in leather finishes are rare but possible in low-cost manufacturing. Vasque's tanning sourcing is not publicly disclosed.
Source: FDA ↗What’s reassuring
Antimony in synthetic polyester components
If synthetic uppers contain polyester, antimony catalysts used in manufacturing may leave trace residues; however, no antimony toxicity concerns are established for intact polyester apparel.
The full breakdown
What it's made of and why it matters
Vasque St. Elias boots combine leather and synthetic uppers with a waterproof membrane (likely polyurethane or similar plastic laminate) bonded to the interior. The waterproof performance depends on a water-repellent coating (water-repellent coating) coating, typically fluorine-based, applied to the outer surface. Leather tanning methods and synthetic material composition are not publicly disclosed by Vasque for this model, making full hazard assessment difficult.
The brand's record and disclosure
Vasque, owned by VF Corporation, does not publicly commit to PFAS-free water-repellent coating treatments or disclose tanning chemistry for individual boot models. VF has made general sustainability pledges but has not released product-level chemical inventories for this footwear line. No major recalls or formal hazard warnings have been documented for this specific model, but the brand's silence on waterproofing chemistry is notable given widespread PFAS use in outdoor footwear.
How it compares in its category
Most waterproof hiking boots in this price range ($100-150) use fluorinated water-repellent coating treatments; PFAS-free alternatives exist (brands like Danner and some Salomon lines offer non-fluorinated options) but are less common at entry-level prices. Leather and synthetic hybrid construction is standard. Vasque's disclosure practices are typical of mid-market outdoor brands but lag premium brands that voluntarily test for PFAS.
If you buy it
Minimize skin contact with the exterior water-repellent coating, especially when wet. Wash hands after handling new boots before eating. Avoid machine washing; use gentle hand cleaning with mild soap and cool water. Replace boots when waterproofing visibly fails (water beading stops) or after 2-3 years of heavy use; do not attempt to re-treat with aftermarket sprays unless certified PFAS-free. Leather conditioning products are generally low-hazard if applied outdoors or in ventilated spaces.
