Where these two actually differ

  • We flag Azo dyes and color-based toxins and Antimony in polyester on the New Balance and not on the On Running.
  • We flag Formaldehyde resins in textile finishing, Azo dyes in knit upper, Microplastic shedding from foam midsole degradation and Glue and solvent residues in midsole-upper bonding on the On Running and not on the New Balance.
  • The New Balance is Mesh upper, Fresh Foam midsole, rubber outsole where the On Running is Knit textile upper with foam/rubber midsole; waterproof treatment likely applied, 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.

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 →
