The patellar tendon is prone to damage in the activity of running or jumping. This Jumper’s Knee Strap is designed by Mueller to specifically target the knees during strategic footwork activities such as running and jumping. Since putting on a large knee strap limits the movement that is not worn. For that purpose, this knee strap comes in handy because it is just the right size and fits your desired length. The narrow width allows it to position itself just under the knee so it can stay in place and not hinder the runners while they perform their activities. This strap also relieves the pain after the physical activity has taken place. The lightweight, soft fabric keeps it light so that it doesn’t feel hot or irritating on the body.
