Biotex Calore Merino thermal socks in exfrafine Merino wool, to always keep your feet warm and dry. The extra-fine Merino wool sock has been designed for training and sports activities in cold and winter temperatures. We have chosen to use extrafine merino to make this sock extremely light but very thermal. The Merino socks breathe and warm the foot pleasantly. In the central part, the rib knit wraps the foot more and offers a perfect fit of the sock. In contact with the skin, the sock returns a pleasant natural sensation.
