KJ Shell XH ExtraHard (1 unit)

This is the hardest shell available. Replacement upper and/or lower Shell for XR3 and Pro series model sizes L-XL only. At certain cases may be adjusted to S-M size boots as the lower shell only (will require KJ Sole 7 Pro to be attached if used as the lower shell).
 
Shells don’t need any special care. However, over-used T-Springs put additional stress on the shells. If the T-Springs are not changed after a maximum 80 hours, the chances of having a shell break increases. Shells may break occasionally, after a certain period of usage and time, this varies depending on the usage conditions. The upper and lower shells are universal. There is no need to specify ‘upper’ or ‘lower’ when ordering replacements.
 
Note: Sold as a single unit!
