I loooovvveeee these boots!! I am 56 140lbs. I am a true size 7.5 and so I ordered them in 7.5. They fit perfectly. However, I have a fairly narrow foot, so if you have a wider foot, I would go up a size, maybe 2 depending on how wide your feet are. They are the perfect size heel also. I typically don't like wearing heels too high for 2 reasons, 1: Im already pretty tall, and 2: my ankles suffer greatly. I would definitely recommend these boots. They are very sexy and I know my boyfriend will love them.
