Reinforced fabric in key areas to protect ankle, toes and nails from the rough demands of trail running and increase the overall durability of the sock.

Trail running is not road running. Feet are constantly required to flex and adapt to ever-changing terrain, and footwear must follow the pace. Designed with shock absorption and protection in mind, the 4th generation Pro Racing Socks Trail take Compressport technologies up a notch to support all your off-road adventures. A trail-specific weave around the forefoot and lower leg is sturdy yet ventilated, quickly wicking away moisture to prevent irritation. The thicker instep fabric reaches higher than our running models for added protection, and a dedicated knit around the ankle offers reassuring stability in rocky terrain. A brand new, wider toe box offers a more ergonomic fit and improved proprioception, allowing the toes to grip and balance intuitively on uneven ground. Tough terry cloth padding covers all the toes to dampen impacts on fast, jarring descents. An improved 360° arch support boosts blood flow and stops the fabric from twisting and folding, avoiding blisters and irritation as the miles wear on. Signature dot technologies offer strategic protection from the outdoor elements in areas known to be problematic for trail runners. Both malleolus bones are covered by large sun-shaped dots to prevent bruising from flying feet. Two lateral rows of 3D.Dots cover the fibular muscles, stimulating the sensory receptors to improve proprioception and stability of the ankle. A wide pattern of 3D.Dots run up the Achilles tendon for added padding and support, surrounding a line of Flat.dots for ventilation. A denser weave underfoot further reduces vibration, with 3D.Dots cushioning impact and giving the foot a solid grip in the shoe. These dots also help increase venous return and delay fatigue so you feel fresher for longer. Higher than the Run Sock, the trail version offers increased protection to the lower leg and ankles, with more durable fabrics to resist the tests of nature. An ergonomic tab at the back adds a touch of comfort and, to ensure you don`t mistakenly pick the wrong sock, the discipline is discreetly embroidered on the inside. There are no two paths about it: this is a high-performance trail running sock that is as tough and durable as you are.
