The CW-X 3/4 Pro Tight unites the major joints of the leg to offer optimum muscular support for activities with linear movement, such as running and Nordic skiing. The patented CW-X Support Web™ brings the hips, knees and ankles into proper alignment, reducing impact and load to the legs. The CW-X Support Web™ also creates a suspension system for the hamstrings and quadriceps, reducing workload in both the pull and push phase of the running motion. Combined with targeted variable compression to increase circulation and reduce fatigue, your muscles don’t have to work as hard over time and your legs will feel fresher. 80% nylon/20% Lycra® four-way stretch fabric. Imported. PLEASE NOTE: Image shown is two-tone, so the webbing can be seen. Tights are actually solid black.
