DetailsLasting Size Chart A short and thin women's trekking sock made from single knitting. These socks contain merino wool, which is a unique natural material, and COOLMAX fibers - a polyester material. Because of this combination, moisture is quickly removed from the skin, thus increasing physical performance and comfort during sport activities or walking. The toe and heel sections are made of a smooth knit, which provides high mechanical resistance. Wool has excellent antibacterial properties and reduces unpleasant odors. Elastic around the ankle keeps sock firmly in place. The sock is finished with a thin elastic welt with a loop for easy sock tension, as well as elastic bandage in the foot, and a seamless toe.
