Restore maximum strength, stability, and structural reinforcement to your rebound shoes with original Kangoo Jumps® Extra Hard Shells - the most rigid and supportive shell available in the Kangoo Jumps range.
Engineered specifically for PRO series models (can be adjusted to XR3 series, too), the Extra Hard Shell is designed for users who require the highest level of resistance and durability under intense rebound conditions. Ideal for athletic training, powerful rebound sessions, and heavier users, these shells provide superior structural support and an exceptionally firm rebound response.
The Extra Hard Shell is primarily intended for XR3 and PRO series boots in sizes L-XL, where maximum reinforcement and stability are required. However, it may also be adapted for S-M sizes as the lower shell only.
When the Extra Hard shell is used as the lower shell, it requires the original KJ PRO Non-Slip Tread / Sole.
Whether replacing worn components or upgrading your rebound setup for greater control and durability, genuine KJ Extra Hard Shells help maintain optimal safety, performance, and rebound integrity.
Compatible with both upper and lower shell positions, these shells feature a universal fit design (no need to specify upper or lower when ordering).
