Women's Fresh Foam Arishi v4 Shoes vs Women's Excursion TR17: which is safer?

Where these two actually differ

• We flag Azo dyes and color-based toxins and Antimony in polyester on the New Balance and not on the Saucony.
• We flag Formaldehyde-releasing finishes in synthetic textiles, Durable water repellent (DWR) coating chemistry and Foam degradation and micro-particle shedding on the Saucony and not on the New Balance.
• The New Balance is Mesh upper, Fresh Foam midsole, rubber outsole where the Saucony is Synthetic mesh, foam, rubber sole with DWR coating, 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 Saucony grade, at 45% confidence against 72%, because it discloses less.
