The cutting edge product of Kangoo Jumps is not limited to amateurs. Highlighting Kangoo Jumps Pro 7, a sturdier series designed for extreme use and exercise for athletes and sports enthusiasts. This model has no weight limit. Just like the other series, professional athletes and heavier people no longer have to worry about joint pains because KJ Pro7 can absorb as much as 80% of impact during exercise. This stylish model has a new and more durable support plate that can withstand two times more impact than the XR series, which is used by most KJ users. This robust, top-of-the-line product has more rebound effect because its spring system has more return energy potential. Steel coil springs can be purchased separately and be added to its TS-Pro6 to make the shoes harder to compress. This latest PRO Series model is ideally designed for strong athletes and/or heavier Kangoo Jumps users. It can return up to 2X the energy of the standard XR Series. This Pro series model features the new TS-Pro7 T-Spring with 4 TwinTurbos PLUS 2 separate Steel Coil Springs which can be added to the TS-Pro7 to make the spring system harder (for extreme weights or extreme uses). It incorporates all the latest patented Swiss KJ technology and the new, heavy duty ShellXH, as well as the SRS (Safety Release System). The NEW multi-size liner, adapts perfectly to several sizes.
