Where these two actually differ

  • We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the New Balance.
  • We flag PFAS in waterproof membrane, Azo dyes in colored upper fabric and Adhesive off-gassing during break-in on the New Balance and not on the Mephisto.
  • The Mephisto is leather, textile, rubber sole where the New Balance is Textile upper with GORE-TEX membrane waterproofing, 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 Mephisto is the one to buy.

Both products run through the same public rubric, which covers 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 →
