Asolo Men's Fugitive GTX
Skip pending PFAS clarity on GTX lining and leather treatment.
Asolo does not disclose PFAS use in this hiking boot. Gore-Tex GTX waterproof lining and nubuck leather treatment are common PFAS application points, but the brand provides no information on their approach.

What Asolo Men's Fugitive GTX is made of, ingredients and materials
The Fugitive GTX pairs nubuck leather (a sueded, buffed cattle hide) with Gore-Tex waterproofing membrane as the lining. Nubuck itself is a natural protein fiber with no inherent chemical hazard, but leather tanning and finishing can introduce heavy metals (chromium, lead) and formaldehyde resins in dyes and waterproofing treatments. Gore-Tex GTX lining is a Teflon-family coating composite engineered for water resistance and breathability; its chemistry inherently relies on fluorinated compounds, which are the source of the PFAS concern flagged separately.
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.
Heavy metals
Nubuck leather tanning and nubuk-specific buffing treatments may involve chromium or lead compounds; Asolo does not disclose tanning method or audit results, so residual metal levels are unknown but consistent with leather footwear as a category.
Source, FDA ↗Formaldehyde / VOCs
Leather dyes and waterproofing finishes applied to the nubuck may contain formaldehyde releasers for durability; no public specification sheet confirms or excludes this, making assessment uncertain.
Source, ATSDR ↗Azo dyes in nubuck pigmentation
The nubuck's brown coloring may rely on azo dyes, which can release aromatic amines under sweat and friction; no disclosure clarifies dye chemistry or restricted substance testing.
Gore-Tex GTX membrane degradation and leachables
Gore-Tex membranes are durable but can shed microparticles and leach fluorinated compounds into sweat or water under wear and cleaning; the extent of exposure in footwear is lower than in clothing but remains undocumented by Asolo.
What’s reassuring
Adhesive residues between upper and lining
No specific hazard reports exist for Asolo boot assembly adhesives, but the bond between nubuck and membrane is mechanically stressed during wear and can fail prematurely if heat or humidity degrades the interface.
The full breakdown
The brand's record and disclosure
Asolo is an Italian footwear manufacturer owned by Dolomite SpA and does not publish detailed chemical composition or leather tanning certifications in public marketing materials. The brand has no widely documented PFAS disclosure statements or third-party environmental certifications (such as Leather Working Group environmental audit ratings) readily available to consumers. This silence on waterproof lining chemistry and leather treatment standards is itself a transparency gap that prevents informed assessment of non-PFAS hazards.
How it compares in its category
Hiking boots with Gore-Tex linings are standard in this price and performance tier; the PFAS burden is near-universal for breathable waterproofing in outdoor footwear. Nubuck uppers are more common than full-grain leather in technical boots and carry similar chemical risks if tanning and dyeing lack oversight. Boots with synthetic or non-fluorinated water-resistant linings exist but are less common at this performance level and often sacrifice breathability.
If you buy it
Clean nubuck regularly with a soft brush and appropriate nubuck cleaner to prevent dirt embedding and premature degradation of the sueded surface. Avoid harsh heat (direct sunlight for prolonged periods, radiators, or dryers), as high temperature can stress the adhesive bond between lining and upper and degrade Teflon-family coating membranes. Dry naturally indoors after wet use; if waterproofing diminishes visibly (water no longer beads on the nubuck), retire the boot rather than applying aftermarket sealers, which add chemical layers. Inspect stitching and sole attachment annually; replacement rather than repair is more durable for technical footwear.
