Product Details 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 COOLMAXA(R) EcoMade fibers to keep your feet dry and comfortable, and integrated arch support is built in.
