Sidas T-Free Trail Running Socks

T-Free® Technology for Natural Movement

In running, the big toe is crucial for balance, alignment and propulsion. That's why we have 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 when road running.

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

In addition, protective areas strategically placed around the ankle, heel and toes provide impact protection, offering optimal comfort.

The ankle support area guarantees a secure and stable run, while the wide grip band improves adherence, and the reflective band ensures optimum visibility, even at night. Protective areas have been added at the ankles for enhanced comfort.
