Where these two actually differ
- We flag Synthetic fiber shedding and microplastic release on the Brooks and not on the Puma.
- We flag Azo dyes, Formaldehyde resins (finishing agents) and Microplastic shedding on the Puma and not on the Brooks.
- The Brooks is Nylon, spandex blend fabric where the Puma is Cotton/polyester blend socks, no waterproofing, 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, 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 →
