The boots are even more beautiful in person. Which made me that much more sad that I had to return them. The sizing is hard to gauge. I have relatively wide feet, but typically sizing up to an 11 works just fine. I even got an 11W to be on the safe side. The shaft of the boot has great stretch. They managed to come all the way up my very chunky calf with no problems. However, the ankle and zipper area had no give to it at all. There was no way I could zip them up and close the boot to wear. I even had my roommate try them and she wears a size 10 with narrow sized feet. No go for her as well. I'd suggest adding just a little bit of elastic for stretch in the ankle area.
