Where these two actually differ
- We flag Antimony in polyester and Microfiber shedding on the New Balance and not on the Reebok.
- We flag Formaldehyde resins in fabric finishing and Elastomer degradation (spandex breakdown) on the Reebok and not on the New Balance.
- Both carry a flag for Azo dyes, so neither choice avoids it.
- The New Balance is nylon mesh and polyester liner, no waterproofing treatment where the Reebok is nylon, spandex, cotton blend, 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 →
