I got these for a costume, and I got them in a size 9 because I have larger feet. I also have muscular calves, which the makers of these boots didn't seem to take into account. I got them, tried them on and they fit my feet fine--but wouldn't zip up around my leg. I consulted with some of my friends who have gotten their boots in the past but who wear a smaller shoe size. I was surprised to learn that even the size 6 had the same measurements at the top as my size 9 pair. They're poorly designed boots, pure and simple.
