Don't squander the amazing moisture-wicking performance of your Gore-Tex hiking and climbing boots by wearing a pair of cotton socks. Approved for Gore-Tex footwear and suitable for any boot or shoe with breathable fabric, the Bridgedale Women's Trek Sock offers a highly technical multi-fabric design that's specifically designed to keep your feet drier and more comfortable during climbs, backpacking trips and extended day hikes. The innovative Moisture Management System features a moisture-conducting fiber layer against the skin that rapidly transfers perspiration to an outer absorbent layer. Once on the outer layer, the moisture remains away from your skin. It has a forward flex articulation along the top of the sock that helps eliminate bunching and binding. An articulated Y-heel design prevents the sock from slipping inside the boot.
