Where these two actually differ

  • We flag Azo dyes and synthetic dyes, Formaldehyde-based finishing resins, Antimony in polyester fibers and Adhesive and rubber off-gassing on the Diadora 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 Diadora.
  • The Diadora is Textile fabric, likely polyester or nylon blend where the New Balance is Mesh upper, Fresh Foam midsole, rubber outsole, which is most of the difference in these two grades.
  • These two are level, close enough that price and fit should decide it rather than our grade.
  • We are less certain about the Diadora 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 →
