A low-bulk performance sock in our most versatile weight – great for running and racing all year round. Each toe is protected – no skin-on-skin contact – to prevent blisters. And the patented design frees your toes to splay naturally on impact and move independently on uneven terrain. The streamlined no-show length has a protective tab at the heel to keep it from sliding down, mesh at the top works with the COOLMAX® fibers to keep your feet dry and comfortable, and integrated arch support is built in.
