Based on the reviews, I bought a size smaller. I found the length was true to size so they turned out too short for me. I returned them for my usual size, a 7. When I received the 7 I found the length true to size but THE HEEL IS VERY WIDE. Due to the lack of support for my heel I returned the 7 too. Nice boot if you have a super wide heel or don't mind them flopping around.
