Stay-Put Lightweight Crew Socks pack all the sweat-wicking, blister beating benefits as our original midweights, sans the cushioned footbed for a lighter, cooler feel during warmer months. They're cotton-y soft, but fight fatigue and manage moisture like no socks you've ever experienced. Memory knit construction means they stay put on your foot – no bunching, creeping or chafing. NanoGlide nylon in high-wear areas adds durability and fends off blisters, plus mesh zones in the ankle and toe give feet a breather. But the biggest deal is, the polyester we use in our socks is 25 times more durable than cotton, so you're gonna be lovin' these socks for a good long time.
