I just got my Swann ballet flats from Zappos and I am speechless. Theya re SO comfortable. They slipped off my right foot, but I put in a heel insert and it's fine now. My feet are harder to please than anyone I can think of (I have bunions on one foot, flat feet, extra wide width, and one foot longer than the other), but these are great. They might not be so great if you have a very narrow foot though. I'm going to order at least one more pair.
