Chuck Taylor All Star Cx Exp2 4.5 Men A07199C vs Velocity Nitro WTR Men's Running Shoes: 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 Puma.
• We flag DWR coating degradation and potential leachates, Antimony in polyester and synthetic blends and Microplastic shedding from synthetic mesh wear on the Puma and not on the Converse.
• The Converse is Canvas upper, rubber sole where the Puma is Synthetic mesh/knit upper with DWR-treated waterproof 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 Converse is the one to buy.
• We are less certain about the Puma grade, at 45% confidence against 72%, because it discloses less.
