Pure Athlete's High Performance Ski socks are the best tough, thick, winter, over the calf socks for hiking, cross country skiing, mountain skiing, snowboarding, hunting, snowmobile riding, extreme cold weather, and even apres ski! But what makes these mens and womens knee high wool socks so great as warming socks for extreme cold weather socks? These extreme winter ski socks have an innovative blend of super soft and warm merino wool that is naturally moisture wicking, almost waterproof in nature due to merino wools water-repellent properties. This makes them perfect as warm winter socks and accessories for ski, snowboard, work, and other extreme winter activities. Whereas cotton ski and hiking socks can become heavy and sweaty, wool stays light, dry and warm, almost waterproof in nature, which is important on the slopes, winter hiking, or snow sports. During cold weather and winter, the extremities are sensitive because they can become colder faster than the core of the body. The thermal properties of wool traps heat and keeps acting as warming socks so you can stay comfortable in your knee high socks all day! The Pure Athlete High Performance Ski Socks are thick but do not have too much bulk so they are comfortable enough to wear with winter boots, and tall, long enough for ski boots. Supportive, very light comfortable compression, and stretchy elastic ensures these thermal performance ski socks are great for all day wear and will stay in place during any winter activity. The High Performance Ski Socks are unisex and come in several different color options and packs. These quality socks are durable and work as a toe warmer with the insulating qualities of merino wool.
