PossiblePFAS in water-repellent coating treatment (non-PFAS analysis)
Where these two actually differ
- We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the Salomon.
- We flag PFAS in DWR treatment (non-PFAS analysis) on the Salomon and not on the Mephisto.
- The Mephisto is leather, textile, rubber sole where the Salomon is Synthetic uppers, DWR-treated fabric/materials, 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 Mephisto 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 →
