The lightest weight running mini-crew provides maximum comfort with minimal bulk. The design puts fabric around each toe, eliminating skin-on-skin friction that can cause blisters. And it gives your toes freedom to splay, align naturally, and work independently 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 mini-crew length sits just below the ankle for debris protection and cool comfort.
