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.

Features:

• Lightweight, soft cotton-blend fabric for all-day comfort
• Material wicks sweat & dries really fast
• Locked-in fit design keeps sock securely on heel for an adjustment free fit that won't fall down
• Medium cushioning placed strategically throughout foot protects high-impact areas without added bulk
• Mesh panels on top of foot for added breathability
• Built-in arch support helps reduce foot fatigue
