T-Free Trail Crew SIDAS

In running, the big toe is crucial for balance, alignment and propulsion. That's why we developed T-Free® technology in collaboration with athletes such as Jonathan Albon. This technology allows the big toe to move freely and independently, improving your comfort and stability during road races.

The socks incorporate all the innovations expected for road running. The anatomical left/right foot construction, combined with In & Out technology (no cut threads), offers a perfect fit and superior comfort. Polygiene fibres and a breathable mesh underfoot keep your feet cool and dry.

In addition, strategically placed protection zones around the ankle, heel and toe provide impact protection for optimum comfort.

The ankle support zone ensures a safe and stable run, while the wide grip strip improves grip, and the reflective strip ensures optimum visibility, even at night. Protective zones have been added at the ankles for added comfort.
