Scarpa Rush TRK GTX Men's
Skip pending PFAS disclosure on Gore-Tex and water-repellent coating.
This hiking boot uses Gore-Tex waterproofing and nubuck leather with water-repellent coating finish, both commonly treated with PFAS. Scarpa provides no public PFAS commitment or material transparency.

What Scarpa Rush TRK GTX Men's is made of, ingredients and materials
These boots combine nubuck leather (a suede-like abraded leather surface) with Gore-Tex waterproof membrane and a water-repellent (water-repellent coating) finish. Nubuck itself is tanned leather and poses no known hazard beyond normal leather care. The Gore-Tex membrane and water-repellent coating treatment are where PFAS chemicals typically reside in outdoor footwear; Scarpa has not publicly disclosed whether their Gore-Tex laminate or water-repellent coating contain legacy PFAS or PFAS alternatives, which is the critical transparency gap here.
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
Gore-Tex laminates and water-repellent coating finishes are the primary PFAS vectors in waterproof footwear. Scarpa has not disclosed whether this boot uses legacy PFAS, PFAS alternatives, or PFAS-free versions, making the actual exposure status unknown but probable given industry baseline.
Source, ATSDR ↗Antimony in polyester and synthetic blends
If the Gore-Tex backing or any synthetic reinforcement layers contain polyester, antimony trioxide catalysts may be present at low levels as a manufacturing residue. Scarpa does not disclose fabric composition beyond 'Gore-Tex,' so presence cannot be ruled out.
water-repellent coating degradation and re-application with fluorinated products
Water-repellent coating finishes on outdoor footwear degrade with washing and use, prompting consumers to reapply proprietary fluorinated sprays. This can introduce additional PFAS exposure if non-fluorinated alternatives are not available or selected. Scarpa does not recommend specific low-PFAS re-treatment products.
What’s reassuring
Formaldehyde / VOCs
No recalls or reports link Scarpa footwear to formaldehyde resin hazards. Nubuck leather and Gore-Tex lamination typically do not require formaldehyde-based binders, though low-level presence in synthetic overlays or seam tape is possible and not confirmed for this model.
Source, ATSDR ↗Heavy metals
Scarpa sources leather from European tanneries, which generally comply with REACH and EU chemical restrictions. No lead, cadmium, or azo dye violations are on record for the brand, though independent testing of nubuck colorants is not publicly available.
Source, FDA ↗The full breakdown
The brand's record and disclosure
Scarpa is an Italian mountaineering boot manufacturer owned by the Dolomite group. The brand has not published a formal PFAS elimination timeline or material disclosure statement for their Gore-Tex products. No major recalls or formaldehyde resin controversies are on record for Scarpa footwear. Without a public commitment to PFAS-free or PFAS-reduced Gore-Tex alternatives, Scarpa's silence on this issue leaves buyers without assurance.
How it compares in its category
Most premium hiking boots at this tier use Gore-Tex with conventional water-repellent coating, so Scarpa is not an outlier in using these materials. However, outdoor brands like Patagonia and some Merrell lines now disclose PFAS-free membrane options or commit to phasing out legacy PFAS in Gore-Tex. Scarpa has not matched this transparency standard, placing it below category leaders on disclosure, though the actual PFAS load in the finished boot is unknown.
If you buy it
Store dry and allow full air-drying between uses to prevent mold in the membrane and textile. Do not machine wash or expose to prolonged heat above 65 C (150 F), which can degrade Gore-Tex seals and accelerate water-repellent coating finish breakdown. Reapply water-repellent coating every 1-2 seasons of heavy use by using a commercial spray product; avoid fluorinated aerosol formulations if PFAS exposure is a priority. Inspect seams and the membrane edge for delamination or peeling, which signals the boot's waterproof life is ending.
