I followed the other reivews and ordered these a 1.5 sizes bigger than my daughter's street shoes.  She wears a 4 so I ordered a 5.5.  They were way too small so I exchanged them for a 6 1/2.  When I received the new shoes, the outside of the box indicated 6.5 but the shoes inside were 5.5 again.  I didn't have time to try again with this company so I had to order them from another company.  I don't understand why the shoe manufacturer can't just size these according to regular street shoe size.
