ASICS Review, Is ASICS Non-Toxic?

ASICS grades Poor on our four-band scale.
PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Grades are model-based, built from published ingredients, materials, certifications, brand disclosures and third-party lab results where they exist. See the rubric.
What ASICS says and does about PFAS
ASICS publishes a clear PFAS position. Its materials guideline states no use of perfluorinated compounds, and its 2023 sustainability report says it has been increasing PFAS-free water-repellent finishes since 2016 and was switching to PFAS-free materials for the US from January 2025. The same report described that switch as underway rather than finished, and we could not confirm which Gore-Tex membrane its GTX shoes use.

ASICS is one of the brands we researched by hand for our record of what every brand has published about PFAS, where the same question is answered for each of them in one line.
