An ultralight crew designed specifically for runners, this sock delivers performance comfort with minimal bulk. The design puts fabric around each toe, eliminating skin-on-skin friction that can cause blisters. Your toes have freedom to splay, and can work naturally for improved comfort, balance and grip. COOLMAX® fibers and a breathable mesh top keep your feet cool and dry, and the seamless ergonomic construction and integrated arch support provide a secure, slip-free fit. The crew length sits mid-calf to keep out dirt and debris.
