My son loves these shoes and wants to wear them everyday. Based on other peoples review I ordered a 1/2 size up and they are the right length. I was ordering a size 1 in other brands but I ordered a 1.5 in this shoe. They fit perfect, a little room for him to grow but not too big. I think the size 1 would have been too small in another month or so. They seem to run wide though, my son pulls the velcro so tight that there is quite a bit of extra strap hanging over the shoes for both straps. I would have given a 5 star review if they fit more true to size and they were not so wide.
