The v-shaped chevron ribbing on the front of the sleeve provides the same relief as kinesiology tape without having to worry about being "taped up" by a trainer.

The leg sleeves are made with innovative Zensah fabric, which is anti-odor and ultra-breathable. A seamless design means no irritating tags or seams to cause discomfort. Calf Support and Injury Prevention: Micro-ribbing on the back of the leg sleeves provides calf support. Using the leg sleeves while running can reduce calf cramps and lessen fatigue. Pin-point compression provides targeted support where it is needed the most. The compression in the leg sleeves also helps to provide muscle stabilization, reducing micro tears and preventing injuries.

This leads to faster muscle recovery time, as muscles receive more of the oxygenated blood they need to recover. It is also good for traveling, at it helps to reduce leg swelling.
