Elite Light Cushion Tab Limited Edition Performance Socks vs Women's Quarter Crew Socks (6 Pairs): which is safer?

Where these two actually differ

• We flag Azo dyes in textile coloring, Formaldehyde-based fabric finishes, Heavy metals in dyes and pigments and Elastane degradation and microfiber shedding on the Feetures and not on the Puma.
• We flag Azo dyes, Formaldehyde resins (finishing agents) and Microplastic shedding on the Puma and not on the Feetures.
• The Feetures is Merino wool blend, nylon, elastane where the Puma is Cotton/polyester blend socks, no waterproofing, 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.
