The Smartwool Ladies Hike Light Cushion Ankle is a comfortable hiking sock perfect for walking, hiking and mountaineering. Indestructawool technology allows materials to be placed carefully to strengthen the areas that need it the most, by reinforcing the wool with nylon whilst ensuring that Merino wool remains against the skin to give you a soft and comfortable feel without compromising on durability. 4 Degree Fit system allows the sock to stay in place without slipping or twisting giving you the protection and support needed for hill walking and mountaineering. The toe seams are smoothed out allowing it to sit flat against the skin for a comfortable feel. This means less irritation is caused when walking for extended periods of time. Merino wool creates a fabric which is quick drying and sweat wicking. It is ideal for base layers as it is lightweight but warm making it perfect for layering up in colder weather. It is also naturally anti-microbial which helps to keep you smelling fresh.
