KJ Shell S PowerShoe (1 unit)

This is the softest shell available and is a replacement upper and/or lower Shell for Children's PowerShoe models only. KJ Shell S can be adjusted to PowerShoe sizes XS and S.  If used as the lower Shell, will require KJ Sole A PowerShoe to be attached.
 
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!
