Carhartt Men’s Midweight Merino Wool Blend Socks are made of 56% merino wool blended with nylon and spandex. Made in the USA, these sweat-wicking, all-season men’s socks keep feet feeling fresh and comfortable all day long. Temperature-regulating merino wool blend fabric keeps feet cool in summer and warm in winter. Naturally moisture-wicking merino wool and FastDry technology work together to keep feet dry. Mesh insteps let feet breathe while enhanced heel pockets and Achilles’s locks keep socks securely in place to prevent discomfort. Targeted cushioning on heels, arches, and toes protects feet by absorbing shock and reducing friction. Offered in 3 men’s sizes to ensure best fit: 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). Carhartt knows the difference a good pair of socks can make when working outdoors or hiking and camping. Well-designed and made with durable, high-quality materials, Carhartt socks keep hardworking feet dry, protected, and comfortable.
