After reading the other reviews I ordered a size 13 for my kids who are a size 12 street shoe. They are very long, I was concerned at first that they wouldn't fit but it turns out that's just the style. They're supposed to fit very long and narrow and my kids haven't had any issues and dance comfortably. They initially complained about them being "too tight" but after wearing it to one class they got used to that feeling of it hugging their arch.
