Where these two actually differ
- We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the Zamberlan.
- We flag Chromium from leather tanning, Formaldehyde resins in leather finishing and PTFE fumes from Gore-Tex under extreme heat on the Zamberlan and not on the Mephisto.
- The Mephisto is leather, textile, rubber sole where the Zamberlan is Leather upper, Gore-Tex membrane lining, 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.
