Diadora Sestriere-XT 2
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes textile upper, foam midsole, rubber outsole, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What Diadora Sestriere-XT 2 is made of, ingredients and materials
The Sestriere-XT 2 uses a textile (woven fabric) upper, which avoids the chemical complexity of synthetic leather or coated membranes. The foam midsole is typical polyurethane or EVA, materials chosen for cushioning rather than chemical hazard mitigation. The rubber outsole is standard for traction. Textile uppers present lower chemical leaching risk than treated or coated alternatives, though dye and finish composition depends on Diadora's supplier standards, which are not publicly detailed.
What’s concerning
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.
Azo dyes in textile upper
Textile uppers rely on dyes for color; Diadora does not specify whether azo dyes or restricted azo compounds are used. Azo dyes meeting EU or Turkish safety standards are low concern, but confirmation is not public.
Formaldehyde / VOCs
Some textile finishes use formaldehyde-based cross-linking or wrinkle resistance. No evidence this shoe uses such finishes, but supplier standards are not disclosed, and textile uppers commonly receive finish treatments of unspecified chemistry.
Source, ATSDR ↗Polyurethane midsole degradation
Polyurethane foam midsoles can break down with heat, moisture, and age, releasing degradation byproducts. No accelerated testing data is available for this specific shoe; normal wear and storage at room temperature poses minimal risk.
Antimony in polyester (if present)
If the textile upper contains polyester, antimony trioxide may have been used as a catalyst during polymerization. Modern polyester production minimizes residual antimony, and migration to skin is minimal in shoes, but composition and residual limits are not disclosed by Diadora.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
No recalls or reports of heavy metal contamination in Diadora footwear. Textile dyes meeting standard safety export markets (EU, USA) are typically screened for lead and cadmium, though Diadora does not publish test certificates for this model.

The brand's record and disclosure
Diadora does not publish detailed material safety or PFAS disclosure statements specific to individual shoe models. The brand has not issued recalls or safety warnings tied to this shoe or its material line. Diadora's parent company and supply chain transparency are limited in public records; no third-party certifications (like bluesign or OEKO-TEX) are advertised for this model. This silence does not indicate a problem, but limits independent verification of dye and finish standards.
How it compares in its category
Running shoes with textile uppers are the material baseline in the category; this shoe does not use controversial coatings or fluorinated water repellents as far as available information shows. Competitors in this price and performance range typically use similar constructions. Shoes with synthetic or coated uppers carry slightly higher risk of off-gassing or leachable additives, making textile a lower-concern choice by default.
If you buy it
Wash textile uppers gently in cool water to avoid dye leaching into skin or sweat; do not machine wash or bleach. Store in a cool, dry place away from direct heat or sunlight, which can degrade foam midsoles over time. Replace when midsole compression becomes visible or cushioning noticeably decreases, typically 300-500 miles. Avoid prolonged exposure to extreme heat (near radiators, in cars in hot weather), as this accelerates foam breakdown.
