Carhartt knows the difference a good pair of socks can make when working or spending time outdoors. Well-designed and made in the USA with durable, high-quality materials, Carhartt Men's Heavyweight Wool Blend Boot Socks help feet stay warm, dry, and comfortable in wintery conditions. Abrasion resistant yarns in heels and toes add durability and 69% temperature-regulating wool blended with synthetics feels soft on feet and legs. Sweat-wicking technology works on keeping feet dry and mesh insteps allow feet to breathe. For all-day comfort, arch supports and cushioning on heels, arches, toes, insteps, and legs keep feet feeling fresh. Available in men's sizes Large (US Men's shoe size 9-11.5) and X-Large (US Men's shoe size 12-14.5).
