Just because we engineered our At Work™ Socks to work as long and as hard as you do, doesn’t mean we forgot about the importance of comfort in the process. The long-wearing nylon- reinforced foot is heavily cushioned for added protection on the hardest surfaces. True heel and toe pockets conform to your foot’s natural contours, and the rib leg stretches snugly so the socks don’t end up around your ankle or heel. Black socks are 67% cotton/17% acrylic/16% stretch nylon. White socks are 86% cotton/9% stretch nylon/3% elastic/2% olefin. 3 pair. Made in USA. Ht: 11". Men’s Sizes:M(6-8), L(9-12), XL(13-15). Colors: White, Black.
