Men's Hiker Encounter 2-Pack vs Men's Hike Full Cushion Crew Socks: which is safer?

Where these two actually differ

• We flag Antimony in synthetic fibers (nylon reinforcement) and Microfiber shedding (synthetic blend durability) on the Darn Tough and not on the Smartwool.
• We flag Azo dyes and colorant allergens, Elastane (spandex) degradation and leaching and Microbial growth if moisture-trapped on the Smartwool and not on the Darn Tough.
• The Darn Tough is Merino wool blend, no water-repellent treatment applied where the Smartwool is Merino wool blend (merino wool, nylon, 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.
