The UYN One ski socks offer all the features you need to drive down the slopes in their best shape. They have been developed with innovative Zerocuff technology and ensure a perfect fit on the calf without hindering blood circulation and without leaving marks. This increases sensitivity and reduces foot fatigue, giving you a better feeling and a better perception in the shoe. The combination of merino wool and UYNs special Natex fibre makes the UYN One ski socks extremely soft and thermoregulating and ensures exceptional comfort and warm feet even on the coldest days. ZerocuffUnlike classic socks that use a double cuff construction to sit firmly on the calf, the revolutionary Zerocuff technology uses a special construction that allows the sock to have a perfect grip without constricting the leg. Eliminating any restriction on the calf improves blood circulation and increases performance. At the same time, the increased blood circulation helps to keep the temperature of the feet constant and avoid swelling even after long, intense workouts. Cool Air Flow 3D structure with micro-channels for air circulation, keeps feet dry and ensures a comfortable temperature.
