I love Pedipeds! These are no exception. Out of the box, they went on my 3 year old's feet and he wore them for the whole say without any issues. They do seem to fit just a bit tighter than his tennis shoes of the same size. My guess is the leather will "give" with use and will make them comparable.  The hidden velcro closure makes them so easy to get on but doesn't show which keeps them dressy. Looks great with nice slacks and cute with jeans and a sweater.  Definitely recommend!
