Footloose - adjustable high heels

Does anyone remember that show from a year or two ago with Karim - Made in America? In that show a woman had this idea. I don’t completely remember the concept but it seems like that same thing - a customizable high heel.

what’s interesting is the curvature of the front of the sole is quite different for a high heel and a low heel shoe and also usually pretty stiff for high heels… i wonder how comfortable teh low heel version would be then.
