Staple x Brooks Cascadia 1 men vs Chuck Taylor All Star Cx Exp2 4.5 Men A07199C: 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 Converse.
• We flag Azo dyes in canvas and Formaldehyde resin finishing on canvas on the Converse and not on the Brooks.
• The Brooks is Mesh/textile upper with synthetic waterproof treatment, rubber sole 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 Brooks grade, at 45% confidence against 72%, because it discloses less.
