I am usually between a 6 1/2 and a 7, and when I ordered these got the 7's based on the size chart. When they arrive they were too big, and they made a squeaking sound when I walked, so I returned them and got the 6 1/2. The 6 1/2's are perfect! I love these shoes and they are so cute. I recommend if you fluctuate between 2 sizes to go with the smaller size.
