Men's Athletic Cushioned Crew 6-Pack Socks vs Midweight Running Crew Women Socks: which is safer?

Where these two actually differ

• We flag Formaldehyde resin finishing agents, Microfiber and microplastic shedding and Allergic reaction to synthetic fibers or dyes on the Adidas and not on the Nike.
• We flag Azo dyes and colorant residues, Formaldehyde-based dye fixatives and finishing resins, Microplastic shedding during use and wash and Elastane degradation and skin sensitivity on the Nike and not on the Adidas.
• The Adidas is Cotton-blend athletic socks, no reported coating where the Nike is polyester/nylon blend with elastane, 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.
