Where these two actually differ
- We flag Azo dyes and colorant heavy metals, Antimony in polyester and Degradation of applied moisture-wicking finish over repeated washing on the New Balance and not on the Reebok.
- We flag Formaldehyde resins in fabric finishing, Azo dyes and Elastomer degradation (spandex breakdown) on the Reebok and not on the New Balance.
- The New Balance is polyester/nylon blend with moisture-wicking finish 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 →
