Men's Athletic Cushioned Crew 6-Pack Socks vs Wool Micro 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, Formaldehyde resins in finishes, Synthetic fiber shedding and microfiber release and Antimony in polyester blends on the Nike and not on the Adidas.
• The Adidas is Cotton-blend athletic socks, no reported coating where the Nike is wool blend (merino wool primary), 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.
