I love these boots! I purchased a half size down and they fit nicely with thin socks. They look awesome with dark skinny jeans or blk leggings. I have calves that are on the thin side and I'm happy to report that these don't gap or sag (skinny-legged girls, you know what I'm talking about!) I get compliments every time I where them. It's a little warm to wear them now, but they're classic enough for fall & winters to come. I've had them for 4 months and haven't had a problem with the back, stretchy portion doing anything weird, but I'm careful when I pull them on. If you have thick calves, beware.
