Gore-Tex waterproofing likely contains PFAS. No brand disclosure available.
Mizuno Neo Lumina GTX uses Gore-Tex for waterproofing, which traditionally relies on PFAS chemistry. Mizuno provides no public PFAS transparency or alternative waterproof claims.

Material
Mesh/synthetic upper with Gore-Tex waterproof membrane
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
PFAS
Gore-Tex waterproofing relies on fluorinated polymers to function. No alternative waterproof technology is embedded in this shoe; PFAS exposure occurs during wear, washing, and eventual disposal. Mizuno has disclosed no remediation plan.
Source: ATSDR ↗Antimony in polyester fiber
Polyester mesh may contain antimony trioxide as a polymerization catalyst. Levels are typically trace and not a concern during normal wear, but prolonged skin contact in hot, humid conditions (sweating feet) could theoretically increase dermal migration. No Mizuno-specific data available.
Microplastic shedding from synthetic upper
Polyester/nylon mesh sheds microfibers during washing and wear. Gore-Tex membrane itself may fragment under UV and mechanical stress over the shoe's lifespan. This is a category-wide issue, not brand-specific, but accelerated if machine-washed frequently.
What’s reassuring
Formaldehyde / VOCs
No recalls or reports of formaldehyde contamination specific to Mizuno mesh uppers. Standard synthetic footwear adhesives and dyes are regulated under REACH/Prop 65; no excess documented for this brand or product line.
Source: ATSDR ↗Azo dyes (colorfast/toxicity risk)
Mizuno uses standard industrial dyeing for polyester/nylon mesh. No specific batch recalls for prohibited azo dyes reported for Neo Lumina GTX. EU and Asian manufacturers typically comply with azo restrictions, though audit records are not public.
The full breakdown
What it's made of and why it matters
The Neo Lumina GTX uses a mesh synthetic upper (typically polyester or nylon) bonded to Gore-Tex, a Teflon-family coating membrane that repels water while allowing breathability. Gore-Tex's waterproofing mechanism inherently relies on PFAS "forever chemicals" (PFAS) to achieve its hydrophobic barrier, a known limitation of this technology. The synthetic mesh itself poses minimal chemical risk during normal wear, but repeated washing and degradation of the Gore-Tex layer over time may mobilize PFAS particles, particularly if the shoe is machine-washed frequently.
The brand's record and disclosure
Mizuno has not published detailed disclosures regarding PFAS content or phase-out commitments for its waterproof product lines. The brand maintains no publicly announced PFAS elimination timeline comparable to competitors such as Salomon or Altra. Mizuno does comply with standard regulatory limits (REACH, Prop 65) but silence on Gore-Tex sourcing and PFAS intentionality means no transparency advantage relative to industry practice.
How it compares in its category
Running shoes with Gore-Tex waterproofing are standard across premium brands; Mizuno's approach is typical, not differentiated. Non-waterproofed mesh alternatives (Nike, ASICS, Brooks standard lines) entirely avoid the PFAS issue but sacrifice wet-weather performance. If waterproofing is necessary, this product sits in the mainstream middle; no brand in the category has solved Gore-Tex replacement with a proven PFAS-free waterproof yet widely adopted at scale.
If you buy it
Hand-wash in cool water with mild soap to extend Gore-Tex layer longevity and minimize PFAS particle shedding; avoid machine washing and high heat drying. Replace the shoe when tread wear or Gore-Tex degradation (visible water beading loss) occurs, typically 300-500 miles. Store dry in a cool place away from heat to slow membrane degradation. If PFAS minimization is a priority, consider non-waterproofed mesh alternatives for training and reserve Gore-Tex shoes for occasional wet-weather runs only.
