What inov-8 Inov8 Trailtalon Men's Running is made of, ingredients and materials
Inov-8 Trailtalon shoes combine mesh uppers (likely polyester or nylon) with synthetic overlays and a waterproof treatment applied to the fabric. The brand has not publicly disclosed the chemistry of this waterproofing agent, which is the primary chemical concern in this shoe. Mesh and synthetic uppers themselves are standard running-shoe materials with low inherent hazard when not treated.
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
Inov-8 has not published the water-repellent coating treatment formula. Given the poor PFAS safety grade assigned to this product, exposure to PFAS or structurally similar chemicals during wear and washing is a documented concern. Coating degradation over time may increase leaching.
Source, ATSDR ↗Coating degradation and particle shedding
The waterproof coating will wear off over time with use and washing. As it degrades, coating particles or chemical residues may shed into sweat and skin contact; the composition being undisclosed prevents assessment of shedding hazard.
What’s reassuring
Formaldehyde / VOCs
No specific recalls or test results on record for Inov-8 mesh or synthetic uppers. Standard polyester and nylon used in running shoes are not routinely treated with formaldehyde-based finishes, but some synthetic blends may contain trace formaldehyde releasers; no evidence of this in Inov-8 product documentation.
Source, ATSDR ↗Azo dyes in colored mesh or synthetic overlays
Inov-8 shoes are dyed in multiple colors; no test reports or certifications confirming restricted azo dye exclusion are publicly available. Risk is low for shoes in normal use, as skin contact is indirect and azo dye migration is minimal without heavy perspiration or prolonged wet contact.
Heavy metals
No recalls or documented contamination of Inov-8 shoe adhesives or rubber soles with lead, cadmium, or other heavy metals. Standard athletic shoe manufacturing does not routinely introduce these metals unless specifically added to colorants.
Source, FDA ↗The full breakdown
The brand's record and disclosure
Inov-8 has not published transparency reports, material safety disclosures, or certifications (e.g., STANDARD 100 by Oeko-Tex, REACH compliance statements) readily available to consumers. The brand's silence on waterproof coating composition is a red flag in a product category where water-repellent coating (water-repellent coating) treatments increasingly use PFAS or PFAS alternatives. No major safety recalls or chemical controversies are on record for Inov-8 footwear.
How it compares in its category
Trail running shoes with waterproofing are common; many competitors (Salomon, Merrell, La Sportiva) similarly apply water-repellent treatments without disclosure. Some brands now explicitly state use of PFAS-free water-repellent coating or provide material certifications; Inov-8 does not. The mesh and synthetic construction is standard for the price and performance tier, offering no material advantage or disadvantage relative to peers.
If you buy it
Wash in cool water by hand or gentle machine cycle to minimize waterproof coating degradation and any potential leaching during wear or laundering. Avoid heat drying and prolonged direct sunlight, which accelerate coating breakdown and may increase exposure to coating components. Replace or resole when tread wears or upper mesh tears; coating durability typically lasts one to two seasons of regular use. Consider requesting Inov-8 customer service disclose the waterproof treatment composition before purchase if PFAS exposure is a concern for your household.
