Man Hiking shoes Tecnica Forge 2.0 GTX
GTX waterproofing likely contains PFAS; Tecnica discloses nothing
Tecnica Forge 2.0 GTX uses Gore-Tex, a Teflon-family coating membrane typically made with PFOA or successor PFAS chemistry. Tecnica provides no PFAS disclosure or commitment, leaving composition unclear.

What Man Hiking shoes Tecnica Forge 2.0 GTX is made of, ingredients and materials
Tecnica Forge 2.0 GTX uses Gore-Tex GTX membrane bonded to fabric uppers for waterproofing. GTX is a microporous polytetrafluoroethylene (Teflon-type coating) film designed to shed water while remaining breathable. Gore-Tex manufacturing and the waterproof finish applied to external fabrics in most hiking boots rely on PFAS "forever chemicals" (PFAS) to achieve water repellency; Tecnica has not disclosed whether this shoe uses PFAS-free alternatives or confirmed PFAS content.
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.
Formaldehyde / VOCs
Fabric treatments and GTX lamination adhesives in hiking boots may contain formaldehyde-releasing resins. Tecnica does not certify absence; risk is typical for the category and exposure is primarily skin contact during wear, not inhalation.
Source, ATSDR ↗Microplastic shedding from synthetic uppers
Synthetic fabric uppers and GTX membrane shed microparticles during wear and washing. Magnitude is not quantified for this specific model; risk is shared across synthetic hiking boots and increases with abrasion and cleaning.
Coating degradation and delamination over time
Gore-Tex lamination in hiking boots is known to delaminate after extended use, exposing raw fabric underneath and compromising waterproofing. Proper care (no heat, gentle cleaning) extends lifespan; replacement is the only remedy once delamination occurs.
What’s reassuring
Azo dyes in fabric uppers
No recalls or reports of restricted azo dyes in Tecnica Forge 2.0. Standard footwear materials are tested for azo compliance in EU and North America, but Tecnica does not independently certify dye safety.
Antimony in polyester components
If polyester is used in the shoe structure (common in mesh and backing), antimony may be present as a catalyst; concentrations in footwear textiles are typically very low and not on record as a concern for Tecnica products.
The full breakdown
The brand's record and disclosure
Tecnica does not publicly commit to PFAS elimination or disclose chemical treatments in footwear. The company has not obtained OEKO-TEX, Bluesign, or other third-party certifications that would restrict PFAS use or formaldehyde resins in textiles. No recalls or safety controversies specific to Tecnica hiking boots are on record, but lack of transparency on waterproofing chemistry is standard across the hiking boot industry.
How it compares in its category
Most hiking boots with Gore-Tex or equivalent waterproof membranes carry equivalent PFAS concern due to reliance on fluorinated treatments. Boots labeled PFAS-free or using wax-based or silicone water-repellent coating (water-repellent coating) finishes are available but less common and often at higher price or performance trade-off. Tecnica Forge 2.0 GTX sits in the mainstream category with no distinguishing low-chemical credential.
If you buy it
Clean the upper fabric with mild soap and water after muddy hikes to minimize skin contact with treatment chemicals and soil. Do not machine wash or soak the shoe; hand cleaning and air drying preserve the waterproof membrane and coating. Replace when GTX delamination (visible separation of membrane from fabric) occurs or when water-repellent coating beads no longer form on the upper, typically after 2-5 years of regular use depending on cleaning frequency. Avoid heat sources (radiators, direct sunlight for extended periods) that can degrade Teflon-type coating and adhesives.
