Is it possible to customize the kybun shoe?

We only sell the kybun shoe as a complete product. For this reason, it is not possible to customize a shoe with a kybun sole. The only option we see is buying the kybun shoe model that can be worn closest to the foot and then having it customized to the foot by an orthopedic shoemaker.
Of course, this is possible in the case of a sole elevation due to a difference in leg length.
