Well, you asked for it!
Those that you have look like orthopedic or therapeutic shoes. Either because of foot shape issues or because of the need for diabetics to avoid pinching the toes and creating circulation problems, wider toed versions are common.
Here's a slip on version:
Here's some with a less squared look:

Of course, it's entirely possible that whoever designed the shoes you have intended them to have that look as a shoe fashion. However, as you may have gathered by the tenor of many of the posts so far, I'd say that you are either going to have people frown on your choice of a rather clunky shoe style, or sympathetic looks from those who think you need to wear them for corrective or medical reasons. In order to discourage the former and elicit the latter, affecting a slight limp might help.
I'm just curious why it is that you can't go back to the source from which you obtained those shoes and see about getting more, if that's what you want.
