Where these two actually differ
- We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the Nike.
- We flag Undisclosed waterproofing chemistry (fluorinated or otherwise), Formaldehyde resins in leather tanning and finishing, Azo dyes in leather coloring and Adhesive off-gassing between layers on the Nike and not on the Mephisto.
- The Mephisto is leather, textile, rubber sole where the Nike is Leather upper, rubber sole, waterproof coating, 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.
