Made in the USA, Carhartt Men's Midweight Merino Wool Blend Uniform Socks are built to be tough, adaptable, and fit for duty. Ribbed construction and structured heel pockets improve feel and foot positioning without bulk or the threat of hot spots. These men's socks wick sweat, breathe easy, and fight odors on long days on-duty. Reinforced for durability and strategically cushioned for the most demanding routines. 57% temperature-regulating merino wool blended with synthetics feels soft on feet and legs. Available in two sock heights, Crew and Over-the-Calf, and three men's sizes: Medium (US Men's shoe size 6-8.5), Large (US Men's shoe size 9-11.5), and X-Large (US Men's shoe size 12-14.5).
