Where these two actually differ

  • We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the Sof Sole.
  • We flag Undisclosed surfactant composition and PFAS status, Skin and eye irritation from surfactants and Fragrance allergens (if present) on the Sof Sole and not on the Nikwax.
  • The Nikwax is wax-based waterproofing where the Sof Sole is foaming cleaner, aqueous formula, which is most of the difference in these two grades.

Both products run through the same public rubric, which covers 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 →
