My new Franco Sarto flats came today, and I can't decide if they fit or not.

They don't hurt or pinch, although the backs will need to be broken in a bit. I just don't seem to have any wiggle room in the toe box. I guess the best way to describe it...It fits like a sock does. They don't hurt, but they are isn't any extra room anywhere. Is that how they should be, so that you don't walk out of them? I've never worn ballet flats before, so I'm not sure.
I think a half size up would be good...but they're already 11s so 12 is the next option.

Opinions??
