A few more tips:
1. Renew your Kangoo Jumps T-Springs regularly
2. We recommend regularly spraying the buckles and moving metal parts with lubricant (e.g. WD 40)
3. Avoid long and high jumps, the shoes are not designed for that. The risk of shell breakage is high with long jumps, as you usually do not land in the middle of the tread, but rather in the heel area. This increases the load on the upper shell of your Kangoo Jumps boots considerably.
4. Avoid exposing your Kangoo Jumps shoes to large fluctuations in temperature. Since the T-Springs are made of rubber, this is not beneficial for your Kangoo Jumps T-Springs, as the rubber can become porous (when it's cold) or soft (when it's warm).
At the Kangoo Jumps T-Springs we offer 3 different degrees of hardness. Suitable for all original Kangoo Jumps Boots, except for KJ Power Shoes. Separate rubber bands (T-springs) are offered for Kangoo Jumps Power Shoe. The following rubber variants are available for Kangoo Jumps KJ XR3 and KJ Pro7 shoes:
Kangoo Jumps XR3 T-Springs = normal hardness
Kangoo Jumps Pro7 T-Springs = medium hard
Kangoo Jumps Pro6 T-Springs = hard
