Where these two actually differ
- Neither product has a hazard flagged against it, which is uncommon and is why both grade as well as they do.
- The Feetures is Acrylic blend sock with no disclosed treatments where the Smartwool is Merino wool blend, no stated water-repellent treatment, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
Both products run through the same public rubric: 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 →
