These socks are made with Coolmax blended yarn for moisture wicking and Coolwick + Ag yarn that is anti-microbial. This material works to keep your feet dry and comfortable all day long. The Airstrip venting creates a thinner knit along each side of your foot to allow your feet to breathe. Inside the sock, the terry construction provides added cushioning without added bulk, even up the leg portion. There is also built-in arch support to keep you comfortable even when you’re standing for long periods of time. The nylon reinforced heel and toe improve the socks’ durability in wear-prone areas. The spandex reinforcement in key areas helps these socks stay up all day as well. These Wells Lamont Western Boot Socks are made in America.
