The standard size of Jumper’s Knee Strap is a one-size fit band that comes in a variety of colors. The band is designed to the size that is just enough to fit under the knee and provide it perfect balance for runners and jumpers. The reason it is small in width is that for jumpers, and runners, objects in the way of their pace might reduce their speed, so they need to ensure safety as well as speed. The jumper’s knee strap focuses on the patellar region since it is mainly targeting the patellar tendon to remain safe in any knee required action. Joints, especially the sensitive, small and vital ones are critical to ensuring safety for because our entire body’s weight affects our knees.
