We bought these in store and thank goodness we tried them on. They run SMALL. My 5 year old daughter who wears a 12 could barely fit in these. We need a 13 at least for her. My 4 year old who wears a 9.5-10 fits in the 11's in this teal boot. They're soooo cute. Too bad we can't find them for my older daughter. Cutest shoes fod this winter!!
