Men's Athletic Cushioned Crew 6-Pack Socks vs Men's Hike Medium Crew 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 Smartwool.
• We flag Azo dyes in synthetic fiber components and Elastic degradation over time releasing microplastics on the Smartwool and not on the Adidas.
• The Adidas is Cotton-blend athletic socks, no reported coating where the Smartwool is Merino wool blend (primary), elastic, synthetic dyes, 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.
