Trail running is not road running. Your feet must constantly bend and adapt to the terrain. The Pro Racing Socks Trail of the 4th generation have been designed to absorb shocks and provide protection. Compressport technologies support your off-road adventures. A robust, breathable fabric around the forefoot and lower leg wicks moisture away to prevent irritation. The thicker instep material extends higher than in running models, providing additional protection, while a special knit around the ankle offers stability. A wider toe box provides an ergonomic fit and improved proprioception, allowing the toes to grip on uneven ground. The terry padding absorbs shocks during fast descents. A 360° arch support promotes blood circulation and prevents blisters and irritation. Signature Dot technologies offer strategic protection. Both ankles are covered with sun-shaped dots to avoid bruising. Two lateral rows of 3D.Dots stimulate receptors to enhance proprioception and stability. A wide pattern of 3D.Dots runs along the Achilles tendon for cushioning and ventilation. A denser fabric in the footbed reduces vibrations, while 3D.Dots absorb impact and provide grip. These dots promote venous return and delay fatigue, helping you feel fresh for longer. The trail version offers more protection for the lower leg and ankle. It is made from more durable materials that withstand the rigors of nature. An ergonomic tab on the back ensures comfort, and the discipline is discreetly stitched inside. This is a high-performance trail running sock that is as robust and durable as you are.
