ENSURE CORRECT FIT AND SIZING: With your knee slightly bent, use the center of the kneecap as your starting point and measure 6 3/4" up your thigh. Measure around thigh for circumference. Using center of kneecap for starting point, measure 6" down your calf. Measure around calf for circumference. Make sure measure tape is not too tight or too loose. Refer to sizing chart & video for correct sizing. IMPROVED KNEECAP CONTROL: designed to help relieve pain for misalignment of the kneecap. Using a corrective strap, the integrated ring-shaped pad holds the kneecap securely in a natural, central position and prevents drifting. COMFORTABLE & EFFECTIVE KNEE PAIN RELIEF: Incorporated viscoelastic Omega pad surrounds the kneecap (patella) to relieve pain and provide massaging pressure. If you have a tight IT band, the P3 support helps relax the muscles on the outside of the thigh to relieve pain. USED TO HELP TREAT & HELP PREVENT: knee pain, kneecap tracking problems (lateral tracking problems), kneecap dislocation (or subluxation), runner's knee, tight IT band, patella femoral syndrome (or pain), and other knee pains.
