We removed everything and added only the necessary: ​​a protection on the fingers, the antislip under the metatarsals, the ventilation on the upper part, a slight compression on the plantar fascia, a special anti-friction texture on the heel and on the Achilles tendon. The upper height protects the ankle from dirt. The reflective strip guarantees greater visibility at night. The result is a sock that combines comfort, performance, style and protection, suitable for long distances that does not fear your most demanding challenges. Tested in Ultra Trail (Marathon des Sables, Petite Trotte à Leon), Ultra Marathon (Sakura Michi) and Ironman.
