i bought these for my little girl and i bought the same size as another pair by Stride Rite...these were a little wider & longer-- i would say, closer to a 5.5 when compared to the Stride Rite shoe.  It's no big deal to me, it just means she will have to wait a little while before she can wear them. Overall though, the shoes are well made, they are very cute, and i can't wait for her to wear them!
