Where these two actually differ

  • We flag PFAS in DWR water-repellent coating, Formaldehyde in sizing/finishing resins, Azo dyes in synthetic mesh colorants and Antimony in polyester textile on the Mizuno 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 Mizuno.
  • The Mizuno is Synthetic mesh upper, likely with DWR water-repellent finish 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 Mizuno 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 →
