The Sidas T-Free Trail socks are thin, technical and protective socks with a separate zone for the big toe for more comfort and stability when trail running. The big toe plays a crucial role in balance, orientation and propulsion. That's why Sidas worked with athletes like Jonathan Albon to develop T-Free technology, which allows the big toe to move freely and independently.

All the benefits you expect from trail running have been incorporated into the construction of these socks. The anatomical shape of the left and right foot and the In & Out construction (no cut threads) ensure a perfect fit and greater comfort. 

Reinforcements at the toe, ankle and heel protect the foot from damage on the trail. The Polygiene fibres and breathable mesh underfoot keep the foot cool and dry, while the ankle support area provides optimum support for a secure and stable run. The Sidas T-Free Trail socks also have a wide grip band for better support and a reflective band for good visibility at night.
