We stand behind the quality of our products

Sidas T-Free Run running socks are thin technical socks with a separate pocket for the big toe, designed to improve comfort, stability and push-off when running on the road and racing. T-Free technology was developed with trail runner Jonathan Albon, winner of the 100 km UTMB Chamonix. The left and right socks are anatomically shaped and the seamless In & Out construction protects the foot from hot spots.

Key features

  • T-Free – a separate big toe means greater stability and a better push-off.

  • Very thin Synergy Fit knit – technical mesh wicks moisture and ventilates the foot.

  • Reinforced knit around the ankle – ensures a firm fit of the sock.

  • Wide Grip Yarn band – the silicone fibre holds the sock in the shoe.

  • Reflective element – a strip on the back improves visibility when training in poor conditions.

  • Polygiene StayFresh – antibacterial treatment limits odour.

Who the socks are for

These unisex socks are for runners who want to try running with a separate toe and need a light sock for the road and for racing. If you prefer a classic cut without a separate toe, see the Sidas Run Anatomic Light Crew running socks or Sidas Run Anatomic Light Ankle. For more demanding terrain, the Sidas Trail Ultra Race running socks are a good fit. Complete your running gear with the Sidas Run 3D Protect running insoles. You will find more models from Sidas in the socks category.

T-Free

Sidas T-Free technology, developed with trail runner Jonathan Albon, features a separate pocket for the big toe. The separate toe provides greater stability and a better push-off with every running stride.

In & Out

The In & Out construction means that there is no material inside the sock that could press on the foot. It ensures direct contact between the foot and the ski boot, which is important for optimal force transfer when skiing.

Synergy Fit

Synergy Fit is the precision knitting technology behind Sidas socks. The cut is based on an analysis of 300,000 feet and 15,000 boots, so the socks adapt to different foot shapes. A fine 200-needle knit and high elasticity ensure a precise fit around the foot, ankle and calf.

Polygiene StayFresh

The antibacterial treatment Polygiene StayFresh limits the growth of odour-causing bacteria. The socks stay fresh even after a demanding workout or match and can be worn longer between washes.

Grip Yarn

Grip Yarn is a French yarn blended with silicone, used to knit the anti-slip band above the ankle. It improves contact with the skin, limits sock movement on the foot and acts as a second layer of blister protection.
