The Men&';s Liner + Hiker is a perfect sock set for every hiking adventure - from a quick day hike to a multi-day backpacking adventure. The Liner is an ultra-thin baselayer designed to wick away sweat from your foot - keeping it dry and comfortable. Since the toes are separated, skin on skin friction is eliminated, helping to prevent blisters. The Hiker is worn over the Liner for increased cushion and protection. The Hiker mirrors the shape of your toes, providing more room and reducing bunching. Features & 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. Protective Cushion Extra cushioning on the footbed to increase foot comfort.
