My daughter is between a size 12 and 13 so I purchased one of each in the sparkly silver shoe. The 12 was much too tight. The 13 fit but not comfortably.  The shoe fits very narrow and stiff and the straps are much bigger than they need to be for a child's ankle.  Super cute too look at but not comfortable at all according to my daughter. What a shame...they would have been the perfect shoe.
