The woman’s Skyline sock brings Peak series performance with the demand of hiking and mountaineering in mind. These socks are made from the eucalyptus fiber Tencel and Merino wool which are both moisture wicking, quick drying and anti-microbial. Adding Merino wool to the Tencel brings advanced thermoregulation capabilities to the Skyline sock keeping your feet comfortable and dry in cold, warm, or wet conditions. Volumetric compression zones go beyond graduated compression to target specific parts of the foot that not only increases circulation but also provides support while holding the sock in place. Even better is the CrossFlex heel pocket with anti-slip anchor zones that lock the heel in place, because when the heel stays put the rest of the sock will follow. To give you the support you need on long expeditions these socks have a thicker underfoot with reinforced heel and toe for extra padding and durability while the top remains light and thin to keep your feet cool and comfortable.
