Where these two actually differ
- We flag Foam midsole off-gassing or degradation products and Bacterial or fungal colonization in worn shoe on the Brooks and not on the New Balance.
- We flag Azo dyes and color-based toxins and Antimony in polyester on the New Balance and not on the Brooks.
- The Brooks is Mesh textile upper, foam midsole, rubber outsole where the New Balance is Mesh upper, Fresh Foam midsole, rubber outsole, 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.
- We are less certain about the Brooks grade, at 45% confidence against 72%, because it discloses less.
