Chuck Taylor All Star Cx Exp2 4.5 Men A07199C vs F-Fly Max Men's 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 Inov-8.
• We flag Formaldehyde-releasing resins in synthetic textile finishes, Azo dyes in colored synthetics, Waterproof coating degradation and unknown leachables and Formaldehyde releasers in synthetic textile dyeing and printing on the Inov-8 and not on the Converse.
• The Converse is Canvas upper, rubber sole where the Inov-8 is Synthetic textile upper with unspecified 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 Inov-8 grade, at 35% confidence against 72%, because it discloses less.
