Yes, they're cotton socks—but they work harder than any other cotton socks you've worn. They wick sweat so your foot feels cooler, while still giving you that incredible comfort and cushioning you expect from regular cotton. Specifications:
Lightweight, soft cotton-blend fabric for all-day comfort
Durable material wicks sweat & dries really fast
Locked-in fit design keeps sock securely on heel for an adjustment-free fit
Strategic mesh panels on top of foot for breathability
Medium cushioning on bottom of foot for comfort & protection
Odor control technology reduces odor in the sock
Built-in arch support band
