Too small.  I ordered a 6 1/2  for my 11 year old daughter, her normal shoe size.  She couldn't even get half of her foot in them.  Yes, she does have a high arch but most shoes she doesn't have an issue with.  So, I sent the 6 1/2 back and they exchanged them for a 7 1/2, a whole size bigger than what she usually wears.  They were still too small at the top.  If I didn't know any better I would swear they sent me a 6 1/2 again (yes, I did double check the size).  it was like there was no difference between the 6/12 and the 7 1/2.  I sent them back. I gave up and didn't try to order another size.  Disappointed because they were so cute and my daughter loved them.  They even came with extra sparkles just in case.
