Double the activity and double the comfort with the 2IN DEFENDER socks. Thanks to the unique Two Layers construction, these socks feature a double layer of fabric designed to reduce the factors that cause blisters. Three-dimensional micro-channels promote air circulation and help keep feet cool and dry for longer. The effect is enhanced by the exclusive bio-based Natex yarn that instantly disperses sweat and eliminates odour. Strategic protections maximise in-shoe comfort, while the exclusive ZEROCUFF technology allows the sock to stay in the correct position without tightening the leg: reduced fatigue, increased performance.
