I REALLY want to love these shoes, but I just can't. I have the extra large toppers on the classic sole (I don't actually have these corky ones). I find that they pinch my toes and I can only wear them for a couple of hours. I agree with the other lady that they make a very annoying slapping sound when walking, too. I think they would be good for vacations, though, as you wouldn't need to pack many shoes. I would be curious about other toppers and soles, if they also have this problem (tight and loud!).
