The TREK FUNC trekking socks are designed to keep your feet comfortable and blister-free during long hikes. The socks are made with a high percentage of merino wool, which makes them breathable, soft, and quick-drying. The wool also helps to reduce the formation of unpleasant odors. The socks have additional padding in the major stress points on the soles of the feet, toes, and heels, providing extra comfort and support.
