These shoes run extremely large... best to order 2 sizes smaller than you normally wear.  I ordered these for my step daughter who normally wears an 8.  Based on advice from a store, she asked me to order the 5.5, but that is 2 and a half sizes smaller than she normally wears, and they were too small, so I'm exchanging them for a 6.  Ordered some of the men's for my son, 2 sizes smaller than he normally wears fit him well.
