Where these two actually differ
- We flag Azo dyes and color-based toxins on the New Balance and not on the On Running.
- We flag Waterproof coating degradation and leaching, Formaldehyde resins in textile finishing, Azo dyes in synthetic fabrics and VOC off-gassing from synthetic materials and coatings on the On Running and not on the New Balance.
- Both carry a flag for Antimony in polyester, so neither choice avoids it.
- The New Balance is Mesh upper, Fresh Foam midsole, rubber outsole where the On Running is Textile with waterproof coating, 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 On Running 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 →
