It's hard to judge sizes with dance shoes, but Capezio recommends to order the street shoe size for this tap shoe. My daughter wears a size 8 (toddler) in street shoes, but isn't terribly far from needing a size 9. I ordered an 8.5 & 9, since return shipping is free and other reviews say to order a size larger. The width on both sizes was pretty tight, but I remember tap shoes were always tight when I was a little dancer and I confirmed with the instructor that it's ok and they will loosen as they are broken in. However the length on the size 9 was way too big. The 8.5 is still a little bit big, but it gives her room to grow through the next several months of class.
