Kangoo Jumps come in several different colors and are sized for men and women, as well as children. They fit similarly to rollerblades or ski boots, and supposedly require only a 15-minute adjustment period for both seasoned athletes and beginners. In addition to accommodating leg and core fitness routines at home, in small spaces, the boots can also be worn during outdoor runs. Kangoo Jumps mimic the benefits of a stationary trampoline in terms of cardio impact and joint protection. The additional rebound exercises users can perform while wearing them have also integrated Kangoo Jumps into some gyms and specially designed fitness classes. Originally developed by a doctor for rehab patients with knee, hip, and back injuries, Kangoo Jump anti-gravity boots provide former runners with an option for continuing their cardiovascular torture of choice nearly impact-free. Hopefully dog versions are on the way.
