Sidas T-Free Trail running socks are thin technical trail running socks with a separate pocket for the big toe. T-Free technology was developed with trail runner Jonathan Albon, UTMB 100 km winner, and delivers greater stability and a better push-off on the trail. Protective zones at the ankle, toes and heel and the anatomical shape of the left and right sock protect the foot on long trail runs.
Key features
T-Free – a separate big toe means greater stability and a better push-off.
Protective zones – reinforced areas at the ankle, toes and heel for higher durability.
In & Out construction – no cut yarns, for comfort and a precise fit.
Denser knit at the ankle – provides support and a secure fit of the sock.
Breathable mesh under the foot – wicks moisture away.
Wide Grip Yarn band – the silicone fibre holds the sock in the shoe.
Polygiene StayFresh and a reflective strip – antibacterial treatment limits odour and the element on the back improves visibility.
