Brooks (insoles Only) For Men's Adrenaline Gts 24 Running Size12
No PFAS disclosure. Likely water-repellent coating-treated insoles carry typical waterproof coating risk.
Brooks running insoles use foam and treated textiles for moisture management. Brand provides no PFAS information; water-repellent coating treatments in athletic insoles often contain legacy PFAS.

The full breakdown
What it's made of and why it matters
Brooks Adrenaline GTS 24 insoles use polyurethane or EVA foam cushioning with a moisture-wicking fabric top layer, likely treated with a water-repellent coating (water-repellent coating) coating to resist sweat and washing. Foam cushioning itself is chemically stable during normal foot contact; the water-repellent coating treatment is the primary chemical exposure point. The insole is a removable component, so material contact is direct and prolonged.
The brand's record and disclosure
Brooks (Berkshire Hathaway subsidiary) has not publicly disclosed PFAS use or testing for footwear components, which is typical for athletic brands not specifically targeting PFAS-free marketing. The brand maintains general compliance with CPSIA and EU textile standards but does not publish ingredient transparency reports for insoles. No recalls or safety violations related to insole chemistry have been documented for Brooks footwear.
How it compares in its category
Replacement insoles from major athletic brands (Nike, Asics, Adidas) share identical material profiles: polyurethane foam with water-repellent coating-treated fabrics. Brooks is in the middle tier for disclosure; some premium brands (e.g., Superfeet) offer PFAS-free or untreated options, while budget insoles rarely disclose materials. This product is standard industry chemistry without distinguishing safety markers.
If you buy it
Hand wash insoles in cool water with mild soap rather than machine washing to preserve water-repellent coating; air dry completely before reinserting. Foam degrades gradually over 6-12 months with daily running use; replace when cushioning feels noticeably flattened or you experience arch discomfort. Store in a dry location; avoid prolonged heat exposure (over 45C/113F) which can degrade foam structure. Discontinue use if visible cracking or separation occurs.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
water-repellent coating (water-repellent coating) coating chemicals
Brooks does not disclose water-repellent coating chemistry; may include PFAS or PFAS-free alternatives. Direct skin contact via moisture-wicking layer is continuous. Risk is low during normal use but increases with damage to top layer or deterioration over time.
Formaldehyde resins in textile treatments
No documented formaldehyde use in Brooks insole fabric layers. Athletic insoles typically avoid formaldehyde-based finishes (common in apparel) due to foot-contact proximity, but testing records for this specific product are not publicly available.
Polyurethane foam degradation and off-gassing
New polyurethane foam may emit trace volatile organic compounds (VOCs) for the first few days; airing out new insoles in a ventilated space for 24-48 hours before use minimizes this. Off-gassing is not hazardous at the levels expected but detectable via odor.
Azo dyes in moisture-wicking fabric
Brooks' apparel and insoles comply with OEKO-TEX or similar standards that restrict harmful azo dyes. No safety violations on record. Actual dye chemistry is not disclosed but presumed compliant with EU and US textile safety limits.
Antimony in polyester (if present)
Insole fabric may contain polyester components; if so, antimony trioxide is a standard catalyst. Antimony migration into sweat is negligible at normal wearing temperatures. No contamination recalls documented for Brooks insoles.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
