Basically, I've got small (size 5 to 6), flat, and wide (usually wide, or double wide, theoretically triple wide if they made that size) feet. Most brands that make wide shoes won't make sizes that run so small, and vice versa.
For anything other than sneakers, I have to buy all my shoes (including normal open-toed heels) from a specialty store for people with wide feet, otherwise my feet just don't fit. Other than sneakers, I've only ever found open-toed shoes to fit on my feet. This includes most flats. Everything else either just doesn't fit at the store or causes my feet or toes to bleed & breaks quickly. However, this means in years of shopping, I haven't been able to find closed-toe pumps that fit--even the ones at the specialty store don't work. I wore peep-toe once, but it was still causing my toes to bleed after a while, so I gave up.
My job last summer required closed-toe shoes, so I bought and wore Mary Jane type shoes similar to these, even though they were unfortunate looking, because I literally couldn't find a pair of shoes in all the stores I looked through that both fit and were closed-toe:

So, some questions:
1) I get the feeling that shoes like those might not cut it for interviews/firm internships. Is that right?
2) And if so, any ideas of what I should be doing?

This is Anon just because it gives physical descriptors that I don't really want attached to my username, particularly since people do notice and comment on my feet IRL.
