Fly Jumper-Jump Units F501 For Teenager

Product Description

The stilts is defined mainly by a flat spring controlled upon deformation, so that the result is a straight movement relative to the ground. With the riser's functional principle, depressive spring characteristic and backward movement of the force point during deformation are achieved. This supports the natural force point movement in the heels direction at higher loads and allows the runner to transpose his optimal jumping energy. Hence, you can really fly!
