Trail Double socks are double-layer trail running socks, specially developed to minimise the risk of blisters and increase comfort during your run on rough terrain.
Trail runners are often exposed to blisters because of the long distances, wet trails and varied footholds. That's why we have created a technical trail sock with a double construction in collaboration with our athletes, allowing friction to occur between the two socks rather than on the foot.
The socks incorporate all the innovations expected for trail running. The left foot/right foot anatomical construction, combined with In & Out technology (no cut yarns), offers a perfect fit and superior comfort. Polygiene fibres and ventilated mesh positioned under the foot keep your feet cool and dry.
In addition, protective areas strategically placed around the ankle, heel and toes provide impact protection, offering optimum comfort.
The ankle support area guarantees a secure and stable run, while the wide grip band improves adherence, and the reflective band ensures optimum visibility, even at night.Protective areas have been added at the ankles for enhanced comfort.
