Do you ever go barefoot, like around the house? I'd try to maximize barefoot time as much as possible.

Also try some more conventional-looking barefoot shoes. On a budget, you can try to Whitin casual shoes. The new leather boot versions look even narrower, but these are definitely wider than conventional shoes with a conventional look on a budget. Even my sneakerhead fashion-conscious niece said that my cheapo Whitins looked nice.
