An exceptional, lightweight liner that’s been proven on the longest trails – use it as your sock system’s baselayer, or on its own if you want to ride light. COOLMAX and nylon fibers are combined for exceptional moisture management, breathability, durability and softness. The patented five-toe design minimizes skin-on-skin friction that leads to blisters and lets your foot work naturally for better alignment and feel underfoot. Designed as a liner, this ultra-thin crew also works well on its own for warm weather hikes and runs. Features and Benefits Blister Prevention With each toe protected, skin-on-skin friction is completely eliminated protecting your foot from blisters and hot spots. Moisture Management Each toe is wrapped in sweat-wicking material so your foot will be drier and therefore more comfortable than in traditional socks. Total Foot Utilization When your toes are separated and properly aligned, this allows your entire foot to be engaged in any athletic activity.
