Where these two actually differ
- We flag PFAS in Gore-Tex waterproof membrane, Azo dyes in synthetic textile upper, Formaldehyde in textile finishing resins and Heavy metals in synthetic dyes and pigments on the ASICS and not on the New Balance.
- We flag Azo dyes and color-based toxins and Antimony in polyester on the New Balance and not on the ASICS.
- The ASICS is Textile upper with Gore-Tex GTX waterproof membrane where the New Balance is Mesh upper, Fresh Foam midsole, rubber outsole, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the New Balance is the one to buy.
- We are less certain about the ASICS grade, at 45% confidence against 72%, because it discloses less.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
