My only warning is that these shoes run ~1-2 sizes too small. I originally ordered a size 8 for my daughter who is a size 7.5 but they were super tight. I ordered 2 sizes larger which still gives her an inch or so to grow into them.

Side note: My daughter doesn't take ballet but just likes to wear these around the house. They don't sell Robeez (or similar shoes) for the older kids and this is a great alternative, plus they are really adorable. My daughter uses them as part of her dress-up routine when she plays and adores them. She wears them daily and they have held up very well. If she ever ends up taking real ballet lessons I'll be buying this brand again.
