PossibleVolatile organic compounds (VOC) off-gassing from adhesives
Where these two actually differ
- We flag PFAS in DWR coating and GTX membrane, Microfiber and microplastic shedding from textile upper and Antimony in polyester components on the Hoka One One and not on the Mephisto.
- We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the Hoka One One.
- The Hoka One One is textile upper with DWR coating, GORE-TEX GTX membrane where the Mephisto is leather, textile, rubber sole, 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 →
