The M-Sport professional running socks have been designed for intensive use, they are made with a special microtouch polyamide, a dynamic fiber that is soft to the touch and has a shiny and light appearance but at the same time offers high performance. It dries much faster than cotton, thus quickly removing sweat from the skin. The structure is designed to adhere perfectly to the foot and not move in the shoe, with large ventilation areas for greater lightness and breathability. The foot and toe are anatomically shaped to fit perfectly and the heel and toe are made with low friction yarns to prevent the formation of blisters. Profilen fabric reduces friction between shoe, sock and foot and its hydrophobic characteristic helps the skin stay dry. High resistance to washing. Composition: 85% polyamide, 13% Profilen, 2% elastane
