Where these two actually differ
- We flag Chromium or heavy metals in leather tanning, Formaldehyde in leather finishing agents and adhesives, Rubber sole off-gassing (VOC/odor) and Nubuck surface degradation and microfiber shedding on the Danner and not on the Mephisto.
- We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the Danner.
- The Danner is leather/nubuck upper with waterproof treatment, rubber sole 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.
