If what some of you mean by "flips flops" are those things with the little posts that go between your big toe and the second toe, yikes! There's no way I can wear those!
I can wear slides as long as the band that goes over the metatarsal doesn't touch the outside of my big toes near about where the nail ends (don't know if there's a name for that part

)
Support--eh, that's usually the least of my worries. The worst for me are shoes with a low toe box that smashes from above.
Width, nah, not so much of a worry for me.
Sometimes I think that the most we have in common is pain and that nobody else understands us.
