Staple x Brooks Cascadia 1 men vs Women's Fresh Foam Arishi v4 Shoes: which is safer?

Where these two actually differ

• We flag Azo dyes and synthetic textile finishing, DWR coating composition (PFAS or alternatives), Formaldehyde releasers in adhesives and linings and Microfiber shedding from synthetic upper 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 with synthetic waterproof treatment, rubber sole where the New Balance is Mesh upper, Fresh Foam midsole, rubber outsole, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the New Balance is the one to buy.
• We are less certain about the Brooks grade, at 45% confidence against 72%, because it discloses less.
