Where these two actually differ
- We flag Azo dyes and formaldehyde resins in synthetic textiles, Synthetic lining microfiber shedding and inhalation, Gore-Tex membrane delamination releasing particles and Adhesive volatiles (VOC off-gassing) from sole-to-upper bonding 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 Mesh/synthetic upper with Gore-Tex 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 →
