Chuck 70 HI GTX vs Chuck Taylor All Star Cx Exp2 4.5 Men A07199C: which is safer?

Where these two actually differ

• We flag Formaldehyde resins in textile finishing, Azo dyes in canvas or rubber coloring, Membrane adhesive or coating leachates and Microplastic shedding from synthetic fibers and rubber on the Converse and not on the Converse.
• We flag Azo dyes in canvas and Formaldehyde resin finishing on canvas on the Converse and not on the Converse.
• The Converse is Canvas/textile with GTX waterproof membrane where the Converse is Canvas upper, rubber sole, 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 Converse grade, at 45% confidence against 72%, because it discloses less.
