Chuck Taylor All Star Cx Exp2 4.5 Men A07199C vs Feidian Challenger 6 Men Shoe Ir: 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 Li-Ning.
• We flag Formaldehyde resins (textile finishing), Azo dyes (textile coloring) and Adhesive volatiles (sole-to-upper bond) on the Li-Ning and not on the Converse.
• The Converse is Canvas upper, rubber sole where the Li-Ning is Mesh textile upper, rubber sole, 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 Li-Ning grade, at 35% confidence against 72%, because it discloses less.
