Carhartt Men's Midweight Synthetic-Wool Blend Boot Socks fit and stretch with movement so you can stay focused on the task at hand. Carhartt knows the difference a good pair of socks can make when working or spending time outdoors. Well-designed and made with durable, high-quality materials, these men's socks help feet stay dry, comfortable, and protected. Abrasion resistant yarns in heels and toes add durability and 31% temperature-regulating wool blended with synthetics feels soft on feet and legs. Sweat-wicking technology works on keeping feet dry and ribbed channels on the legs allow for ventilation. For an all-day, comfortable fit, arch supports and cushioning on the heels, arches, toes, insteps, and legs keep you feeling fresh on your feet. Sold in 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).
