No fiber technology attracts & repels sweat simultaneously. To keep feet dry, we use sweat repelling fibers on the skin side & sweat-attracting fibers on the outside. Sweat doesn't stick to these fibers, so it moves completely through to the outer layer. CTR Clothing Socks also keep feet drier because our System is self-contained, while other socks must rely on the ineffectively slow process of wicking & evaporation. * Tailored Fit * Cushioned Sole * Ventilated * Anti-Blister * Anti-Microbial Odor Control * 70% Drymax Olefin, 17% Polyester, 7% Nylon, 6% Elastane
