Sida's Trail Running Socks – Endurance Racing Knee

See our entire range from Sidas here!

Sida's Endurance Racing Knee are high-rise trail running and running socks developed for long-distance and ultra-distance running , where endurance, stability and recovery are crucial. With graduated calf compression, the socks help stabilize the calf muscles, reduce micro-vibrations from repeated impacts and contribute to better recovery both during and after the workout.

The socks are very thin but durable around the foot, giving a direct and precise feel to the insole and the ground. The lightweight construction – around 50 grams per pair according to the manufacturer – makes them comfortable even during many hours of running.

To prevent slipping in the shoe, the Endurance Racing Knee is equipped with three silicone-based grip zones under the foot. These maximize contact between the sock and the insole, reducing the risk of friction and blisters, especially in technical terrain and during prolonged exertion.

Additional comfort and function are ensured by breathable mesh zones under the arch of the foot , which effectively transport moisture away and keep feet dry even during intense and long distances. The socks also have support around the ankle and a reflective detail for increased visibility when running in low light.

Designed in France and manufactured in Europe, Sida's Endurance Racing Knee is an excellent choice for trail runners and road runners who want high compression, stability and precision for intense endurance training.
