Chuck Taylor All Star Cx Exp2 4.5 Men A07199C vs Men's Fresh Foam X Hierro v9: which is safer?

Where these two actually differ

• We flag Azo dyes in canvas and Formaldehyde resin finishing on canvas on the Converse and not on the New Balance.
• We flag Azo dyes and textile colorants, Foam off-gassing (midsole) and Antimony in polyester components on the New Balance and not on the Converse.
• The Converse is Canvas upper, rubber sole where the New Balance is Knit textile upper, 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 New Balance grade, at 45% confidence against 72%, because it discloses less.
