When running, the big toe is crucial for balance, alignment and propulsion. That's why Sidas developed T-Free socks technology in collaboration with athletes like Jonathan Albon. This technology allows the big toe to move freely and independently to move, improving both your comfort and stability during road running.

These socks combine all the innovations expected for road running. The anatomical construction (left and right foot) combined with the “In & Out” technology (without cut threads) offers a perfect fit and first-class comfort. The Polygiene fibers and the airy mesh fabric under the foot keep your feet cool and dry.

The ankle support area ensures a safe and stable ride, while the wide grip strip improves grip and the reflective band ensures optimal visibility even at night.

Features:
• “In & Out” construction: increased comfort without cutting threads
• Big Toe Separation: Freeing the big toe to regain comfort and stability
• Ankle Support: Support band for a secure and stable adjustment
• Protection zones: In the area of ​​the ankles, toe cap and heel
• Breathable & airy mesh fabric: maximum ventilation for dry feet
• Wide grip strip: improves grip and synergy between sock and sole
• Odor management: Polygiene StayFresh™ technology for lasting freshness
• Reflective tape: increased visibility even in the dark
