Suffering from FTL syndrome or wiper that has not been relieved orthotics yet quite expensive and no real support from my doctor, I discovered this knee while browsing the Net. While my knee ached martyrdom after 2km of a light jog, I was able to resume a session "test" 6km without any pain because of it! Certainly, it does not heal (I had trouble thereafter, as before), but with rest and anti-inflammatory cream, everything should be back to normal, as it avoids the trauma occurred during the effort. As for comfort, it is optimal, but be careful to follow the instructions and take the correct size. I recommend this product to anyone who suffers from this tendonitis: jogging will not be forbidden!
