Yes, they are also suitable for higher weight categories (please report weight over 85 kg in advance); for classes we have boots adapted for higher load up to approx. 110 kg. For KJ XR3 jumping boots, the load capacity can be increased using stiffer shells or springs. Above 85 kg we recommend replacing the shells with stiffer ones (for adjustments when purchasing new boots, contact us in advance and we will customize them for you). We also offer KJ PRO jumping boots designed for weights up to 135 kg.
