Mens adidas Terrex Anylander Leather Mid Climaproof Hiking Shoes
Adidas Climaproof likely uses water-repellent coating, PFAS status unclear.
Climaproof is Adidas' proprietary water-repellent technology on leather. Adidas has not publicly disclosed whether this coating contains PFAS, typical for many water-repellent coating treatments in hiking footwear.

What Mens adidas Terrex Anylander Hiking Shoes is made of, ingredients and materials
The upper is leather, which requires chrome or vegetable tanning and chemical finishing to achieve water resistance and durability. Adidas applies a 'Climaproof' water-repellent coating (water-repellent coating) coating to the leather surface; this coating class often contains PFAS compounds, though Adidas has not publicly disclosed the specific chemistry of their formulation. The shoe also includes synthetic reinforcement, adhesives, and rubber sole components, all of which may contain residual solvents or off-gassing compounds during the break-in period.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Formaldehyde / VOCs
Chrome-tanned leather (standard in athletic footwear) and synthetic leather finishes often contain formaldehyde-releasing preservatives and cross-linking resins. Off-gassing is highest during the first 1-2 weeks of wear but persists at lower levels.
Source, ATSDR ↗Azo dyes in leather coloring
Adidas does not publicly disclose dye chemistry for this product. Azo dyes are permitted in leather but some formulations release carcinogenic amines under certain conditions (sweat, wear friction). Likelihood depends on supplier, which is not disclosed.
Adhesive and solvent residues
The shoe construction involves glued seams and synthetic overlays; adhesives often contain volatile organic compounds (VOCs) and may off-gas during the first few weeks. Proper airing reduces this risk substantially.
Antimony in polyester reinforcement
The shoe likely contains polyester mesh lining or reinforcement panels. Antimony is used as a catalyst in polyester synthesis; residual antimony may leach slightly into sweat, though levels in footwear are generally low and adhere to regulatory limits in most markets.
Microorganism growth from retained moisture
If the water-repellent coating fails or degrades, the leather and synthetic linings retain moisture, creating conditions for mold and bacterial growth. This is a use-phase hazard dependent on care and climate, not inherent to the material.
How is this PFAS grade calculated?
The brand's record and disclosure
Adidas has not issued clear public commitments to PFAS-free water-repellent coating coatings across its product lines, and their Climaproof technology remains undisclosed. The brand has faced pressure from environmental groups over fluorinated water repellents but has not published reformulation timelines. Adidas does hold some certifications (e.g., Bluesign partnerships) that limit certain chemicals, but these do not guarantee PFAS absence in water-repellent coating treatments. Transparency on this specific product's coating is minimal.
How it compares in its category
Hiking shoes with leather uppers and water-repellent coatings are standard in this price segment; nearly all brands use some form of water-repellent coating treatment. Competitors like Salomon, Merrell, and La Sportiva face the same PFAS uncertainty in their water-repellent coating layers. Alternatives with lower PFAS concern exist but are rare in mainstream hiking footwear and typically cost more or sacrifice water resistance. This shoe is typical for its category in terms of chemical risk profile, not a high-hazard outlier.
If you buy it
Air the shoes out for several days after purchase to minimize exposure to volatile organic compounds from adhesives and finish. Avoid wearing them indoors for extended periods during the first week. Clean and maintain the water-repellent coating per Adidas care instructions (gentle hand wash, air dry away from heat); a worn-out water-repellent layer increases moisture absorption and potential mold growth. Replace the shoes after 300-500 hiking miles or when the sole shows significant wear; do not wash in machine or immerse for extended periods, as this degrades the water-repellent coating layer and may increase off-gassing.
