I love these boots. LOVE THEM. They are so cute and unique, I get compliments on them all the dang time.
 I have 17" calves and tiny ankles - these fit a bit saggy in the ankles and I did have to get the calves stretched, nothing to be done for sagging ankles, sadly. I wore them happily for a few months, until two weeks ago when the first button leapt off. And then another one just ran away when i pulled them out to wear a few days ago. I would LOVE to find some replacement buttons, maybe I'll adhere some funky ones in the place of the missing ones?
These are really comfortable to wear to walk around in, and I have a wider foot that usually gets smooshed in wedges or heels if I wear them longer than ten minutes. I bought a 9, I am an 8.5, and I would say if you're planning on wearing wool socks or deluding yourself on your shoe size, get a half size up. I wish I had gotten my actual size instead of listening to the reviews here.
