The Nike Unisex Racing Ankle Socks are designed for athletic performance. They are designed using NikeGrip technology for slip-resistance and stabilizing support. These white/socks are made from a blend of polyester, nylon, and elastane with a ventilated mesh throughout the top of the foot to keep you cool. The Nike racing socks wick sweat as you run, helping you stay dry and comfortable. They are made using form-fitting fabric to keep your feet snug and secure.
