Compressport UTMB Pro Racing v4.0 Trail Socks

High-tech trail running socks that protect, absorb shocks and support your feet during your toughest off-road challenges.

The Pro Racing Socks from Compressport deliver support in many different ways with new and improved features for the 4th generation of this sock. The socks provide Achilles protection thanks to the cushioning effect of the 3D dots at the rear of the sock, protecting the Achilles from friction and pressure. These 3D dots are also on the inner part of the malleolus to help reduce shocks. The massaging acupressure activates blood circulation by massaging the soles, while arch support provides venous return and recovery. A 360° slight compression band around the arch support prevent the socks from turning or sliding down during movement, for minimal distractions. Most importantly, it stimulates venous return, delivering more tonicity to your stride.

Specially designed for right and left feet, the socks adhere to the anatomy of each foot and help to maintain your performance. Designed to include striped vented zones around the feet for ventilation, allowing cool air to permeate and hot air to escape, preventing an intolerable heat build-up. Combined with its fast-drying fibres, the sock dries very quickly, so you avoid wet feet. The 3D dots do not retain water and instead help facilitate its discharge, ensuring dry feet at all times. Seamless and elastic-free, the sock does not cause irritation or pressure, so the forefoot can lie comfortably in the ergonomic toebox. The toe box is wider than in previous models to improve proprioception. The fabric features reinforcements in key areas to protect the ankle, toes, and nails from the demands of trail running, while increasing overall durability. Completing the socks is the UTMB 2026 logo on the top of the right foot.
