INOV8 Trailtalon Men's Trail Running Shoes
Skip until brand clarifies waterproof treatment chemistry.
Inov-8 does not disclose PFAS status or waterproof coating chemistry. Trail running shoes commonly use water-repellent finishes that may contain PFAS.

What INOV8 Trailtalon Men's Trail Running Shoes is made of, ingredients and materials
The Trailtalon uses synthetic uppers (likely polyester or nylon blend), a synthetic midsole, and an unspecified waterproof coating. Synthetic uppers avoid some natural-fiber risks but introduce concerns around the waterproofing treatment itself, which is often PFAS-based in performance footwear. No data on dye chemistry, antimony content in polyester, or formaldehyde-resin use in this model is publicly available.
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.
PFAS
Unspecified waterproof treatment in performance footwear almost certainly contains PFAS; Inov-8 has not disclosed or ruled out PFAS chemistry. Direct skin contact and sweat exposure elevate bioaccumulation concern.
Source, ATSDR ↗Antimony in polyester
If uppers are polyester, antimony trioxide (catalyst in polymerization) may be present in trace amounts. No specific data for Inov-8; typical levels in apparel polyester are below acute concern, but not ruled out.
Coating degradation and migration
Synthetic waterproof coatings degrade with wear, UV exposure, and washing. As the coating breaks down, residual monomers and uncrosslinked polymers (including PFAS precursors) can leach into sweat and absorb into skin; this is a documented pathway in performance footwear.
What’s reassuring
Azo dyes in synthetic uppers
No public testing or recall data specific to Inov-8 Trailtalon for banned azo dyes (e.g., those releasing carcinogenic amines). Material is synthetic and dyed, but no specific hazard is documented for this model.
Formaldehyde / VOCs
Synthetic textiles sometimes use formaldehyde-releasing resins for shape-hold or water-resistance. Inov-8 does not disclose resin chemistry; no recalls or reports are on record for this shoe.

The brand's record and disclosure
Inov-8 has not publicly disclosed the chemistry of its waterproof treatments or committed to PFAS-free formulations. The brand does not advertise independent testing results or certifications (e.g., bluesign, GOTS, MADE SAFE) that would signal transparency on chemical inputs. This silence is notable given the prevalence of PFAS in performance footwear and growing consumer awareness of the issue.
How it compares in its category
Most trail running shoes in this price range use synthetic uppers and water-resistant coatings, many of which are PFAS-based. Competitors vary widely in disclosure, some brands (Salomon, ASICS) have begun publishing PFAS reduction pledges or testing data, while others remain silent. Inov-8's lack of clarity puts it below the transparency standard of leading brands but not unusual for the segment.
If you buy it
Minimize heat exposure to the coating and uppers (avoid hot water cleaning, direct sunlight storage for extended periods) to reduce leaching risk. Wash with cool water and mild detergent, air-dry away from heat. Inspect the coating annually for cracks or peeling; degradation can expose underlying materials and increase migration of residual chemicals. Consider rotating with other shoes to limit cumulative wear and off-gassing of any volatile compounds in the synthetic materials.
