Hmmm...
There are several brands that make custom shoes based on foot castings.

Other brands too, with a bit of hunting.
Not particularly cheap, but you should get a professional well fitted shoe that should last a very long time. You might want to work with them on cleat position. So, for example a cleat position towards the inner side to reduce crank rub.
I have wondered if other sports shoes could be modified to make usable bike shoes. I have seen some shoes with sole lugs that have fairly rigid soles. Soccer shoes?
