Dexter makes them as well
Yeah that's the dexter powerstep most think it's okay, but it's bulky and heavy on the foot.
The thing on the korean shoe is just on the tip though it's just made on that shoe though.
As they say "rubber toe cup allows a complete kick-step capability."
The Korean shoes looked pretty similar to the Dexter Exxtra's.
They had changeable soles with the little round changeable disks to fine tune the slide and changeable heels.
