With the X-SOCKS SKI CONTROL 4.0, you will gain the decisive milliseconds advantage when skiing as a competitive athlete or ambitious hobby skier. High-tech yarns and integrated patented technologies effectively protect the foot from the shin to the toe. The Suppronation footbed ensures a firm hold, corrects misalignments and thus reduces the risk of injury. The innovative HelixCoil system lays as a concentric double spiral around your calf and exerts a muscle-stabilising effect. The ISO blocker also reduces the point pressure on the foot. But the foot is not only well protected. It also stays dry and warm, because moisture evaporates quickly over the microfibres made of breathable Mythlan and the thermoactive Xitanite yarn ensures a constant feel-good temperature.
