Where these two actually differ

  • We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the SOREL.
  • We flag Fluorochemical water repellents (Gore-Tex membrane), Formaldehyde resins (leather tanning and finishing), Rubber sole off-gassing (volatile organic compounds) and Azo dyes in leather or textile linings on the SOREL and not on the Mephisto.
  • The Mephisto is leather, textile, rubber sole where the SOREL is Leather, rubber sole, Gore-Tex membrane, 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.
