CW-X Stabilyx tights have been designed to provide optimum targeted support to the core and knees. These tights are ideal for runners and athletes who are always on the lookout for the best form of knee support. The patented CW-X Support Web acts similar to kinesiology taping to stabilize the knee and reduce vibration for increased efficiency. It also harnesses the midsection, supporting the lower abdominals, hips and back to channel power through the core. Variable compression facilitates circulation during and after activity thereby minimizing lactic acid build-up so that you can be active longer and recover faster. To add to this is the six reflective flash strips and reflective logo. Together, they are capable of providing a 360-degree visibility for nighttime activities. Whenever you’ll run with them, you can be sure to not let your legs feel heavy or tired anymore.
