adidas Men's Terrex Anylander Mid Rain.Rdy Hiking Shoes
water-repellent coating hiking shoes lack PFAS transparency; wait for brand disclosure.
Adidas Terrex rain hiking shoes use water-repellent coating water-resistant treatment but provide no public PFAS information. Standard outdoor shoe coatings often contain PFAS; Adidas has not confirmed PFAS-free status for this model.

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.
Formaldehyde / VOCs
Synthetic textile uppers may contain small amounts of formaldehyde-releasing resins used to set dyes or add crease resistance. Adidas does not publicly certify formaldehyde-free production for this model; levels are typically below regulatory limits but not zero.
Source: ATSDR ↗Azo dyes in colored synthetic fabrics
The shoe's colored nylon/polyester upper may be dyed with azo compounds; while regulated in the EU, some azo dyes can break down under sweat and heat to form carcinogenic amines. No third-party testing is on record for this specific product.
Antimony in polyester components
Polyester textiles and synthetic rubbers may contain antimony trioxide as a catalyst; typical exposure is negligible through intact fabric, but degradation over time or washing can increase migration. Adidas does not report antimony content or limits for this line.
water-repellent coating degradation and leaching
Fluorinated and non-fluorinated water-repellent coating coatings gradually wear or strip through washing and UV exposure; worn coatings may leach unreacted monomers or degradation byproducts into sweat or soil. Lifespan is typically 1-2 years before reapplication is needed.
What’s reassuring
Lead
Adidas sourcing typically meets EU and US limits for heavy metals in colorants; no recalls or testing evidence suggests exceedance for this model, though independent verification is not publicly available.

What it's made of and why it matters
Adidas Terrex Anylander Mid uses a textile upper (likely synthetic mixed-fiber mesh or nylon) with a water-repellent coating (water-repellent coating) coating applied to the surface. water-repellent coating coatings on textiles commonly contain fluorinated compounds (PFAS) to achieve water-shedding performance, though Adidas has not disclosed the specific chemistry. The midsole and outsole are typically thermoplastic polyurethane or rubber compounds; these carry lower inherent toxicity risk but depend on manufacturing quality.
The brand's record and disclosure
Adidas has not publicly committed to PFAS-free water-repellent coating alternatives or disclosed which products use fluorinated vs non-fluorinated water repellents. The brand has faced criticism from environmental groups for PFAS use in performance footwear lines but has not issued a detailed remediation timeline. No major product recalls for chemical hazards in this model are on record. Adidas does hold ISO 14001 environmental certification, but this does not mandate PFAS phase-out.
How it compares in its category
Most mainstream hiking shoes in the mid-range (Merrell, Salomon, The North Face) use similar water-repellent coating-coated textile uppers; PFAS presence is industry-standard unless explicitly labeled 'PFAS-free.' High-end alternatives (Patagonia, some Scarpa models) now offer certified PFAS-free water-repellent coating options, though at higher cost. Budget and mid-market brands rarely disclose water-repellent coating chemistry, making direct comparison difficult. Adidas' silence is consistent with competitors but not a safety advantage.
If you buy it
Wash the shoe in cool water (under 40C) with mild soap; heat can degrade the water-repellent coating and potentially release trapped chemicals. Air dry only; never machine wash or tumble dry. Reapply water-repellent coating spray (PFAS-free formulations available) every 12-18 months or when water no longer beads. Replace the shoe when upper seams fail or the midsole flattens (typically 400-600 miles), as degradation may increase leaching risk. Store dry in a cool place to minimize compound volatilization.
