How to adjust KJ rebound shoes to the weight & condition of the user?
Select the appropriate Kangoo Jumps rebound shoe model The KJ-XR3 series: features the Standard IPs, it can be used by anyone, adult or teen a long as they weigh no less than 70 lbs or 32 Kg. If weight is above 200 lbs or 90 Kg., the rebound effect can be minimized depending on the level of energy used to compress the lPs. For heavy weights and strong level of energy, we recommend the Pro model as a better option. The Pro7 series: features a harder lPs (t-spring PRO7). It is suitable for heavier individuals or athletes (think professional football player who want a harder workout or participates in extreme sports. The Power Shoe series: feature a softer lPS suitable for pre-teens and teens and will accommodate weight ranges from about 40 lbs (18 Kg) to 120 lbs (55 Kg). However, we do not recommend the Power Shoe for adults as the shells are thinner, thus the lPS softer, Adults with small feet should be encouraged to try the Adult KJ-XR3 model in size XS.
