Asterisk Cell Knee Protection System

The Cell Knee Brace is without question one of the most technologically-advanced Knee Protection Systems available and combines several patented revolutionary design concepts. The Asterisk Cell is built on 10+ years of time-tested and proven designs and is completely customizable to the leg yet remains extremely rigid to prevent injury. The low profile strapping system, natural free-motion hinge, tibial plateau-capturing frame design, brace-to-boot tether attachment, and a full time-full coverage patella cup, sets this knee brace decades ahead of the rest.

Sizing Notes!

Locate the middle of the kneecap and measure around the leg. Measurements should be taken directly on the skin with a straight leg supporting your full body weight using a soft tape measure. (If soft tape measure is not available, a piece of string or yarn may be used to calibrate the leg's diameter.)

SM 33.02-35.24
