7-Year™ Socks have always fought fatigue, controlled temperature, managed moisture and cushioned shock like no socks you've ever experienced. And now they’re doubly tough thanks to a new fiber blend with more than twice the abrasion resistance of the originals. What’s more, the performance knit feels soft, fends off blisters and dries in a blink. Even keeps feet cool, thanks to the temperature-managing magic of COOLMAX® EcoMade polyester made with 100% recycled materials. And here’s a plus: When you're working on hot, steamy days, the ankle-baring no-show design won't give you pale "contractor's ankles" on your suntanned legs.
