Size runs very small. When I got the right size, they were so ridiculously uncomfortable! I had to wear them as a bridesmaid in a wedding and within minutes all NINE (Yes 9) bridesmaids were in so much pain from these shoes! They didn't just start hurting after hours of dancing and whatnot... They hurt immediately and never stopped. And not just me, but all 9 of us who all had these exact same shoes on. Even some of the girls who tried to see if breaking them in weeks before the wedding would lessen the pain but it did not! Do not buy these shoes your feet will never forgive you!
