When the trail demands stability, cushioning and some welcome freshness, we answer with the Ultra Trail Low Cut Sock: the perfect performance sock for trail runners who require comfort and support when the going gets tough. Equipped with the same high-tech features as its crew-cut sibling, this low-cut running sock offers a reinforced terry toe box to protect you from bruised toes and nails on technical descents. Thicker terry bands underfoot and at the base of the Achilles further absorb shocks from the terrain and pressure from your running shoes. Our 360° arch support provides targeted compression to boost blood flow and delay fatigue whilst preventing the material from twisting and causing blisters. The brand-new X-strap is specifically developed for increased stability in rocky terrain, firmly wrapping around your ankle for steadfast support. Its light compression works with the arch support to enhance your performance as the hours wear on. Technical dots underfoot increase airflow and grip in the shoe while large terry dots on the malleolus bones protect from flying feet and stones on technical sections. With sweat-wicking mesh on the upper foot, the Ultra Trail Low Cut Sock is ideal in hotter conditions or combined with Compressport calf sleeves to provide the support you need during the most demanding trail running races.
