The sock contains a special and innovative Cupron yarn, which is characterized by a wide range of antibacterial and antifungal properties. The use of this yarn in Rohner's socks reduces odor and skin problems on feet. It ensures optimal power transfer between foot and shoe. The high-quality plush in the foot and shin area and the reinforced high heel ensure a high level of comfort. The Copper Jet sock won the ISPO Gold Award in the snow sports category in 2020!
