Built with targeted compression on the calf, the Soar Running Dual Fabric Tights 2.0 will keep you supported whether you are pounding the pavement or heading for the trails. Helping to keep your muscles locked in place to improve venous return & performance, reducing the risk of injury and accelerating recovery times. The French-made fabric on the calf is woven, which gives it remarkable compressive qualities without added weight. A slightly thicker, warmer Italian fabric on the quad keeps the temperature just right. Silicone grippers at the ankle give a snug fit, & reflective details on the thigh & ankle zip keep you visible on dark runs.
