Engineered as both mens and womens for wearing all day on the slopes and constructed from high-quality warm Merino wool, these ski socks will stay light, breathable, and dry throughout any cold weather outdoor sports activity. Whereas cotton ski socks retain moisture and can become soggy and heavy, Merino wool is naturally moisture resistant, wicking moisture away to keep feet dry and warm! Not only do the Original Ski Socks work for skiing and snow sports, but any snow or winter activities and outdoor sports such as hiking, trekking, camping, hunting, ice fishing, and playing winter sports. The Pure Athlete Original Ski Socks are designed with performance zones that have ideal lightweight cushioning and shin guard features in ski boots. Cushioning is thin enough to be breathable, but warm enough to act as a thermal sock in cold weather.
