These are pretty good quality shoes; however, they do not run street size.  My daughter wears size 2 & currently has size 2 ballet shoes that do run street size.  I ordered a size 4 & size 5.  The 4's are the same size as the 2's she currently has.  The 5's probably fit like a size 3.  Ended up sending the 4 back & kept the 5 for next year.
