These fit true to size (I'm a true 8.5). I have smaller calves and can wear them with skinny jeans but they still hold up wearing tights. They are extremely comfortable and I didn't have any problems with the zippers (although they are a little noisy). One thing I didn't particularly like was the distressed look (I don't need to look poorer than I am) so I bought some shoe polish and covered up those areas. I love them, the price is a bit much but I've been looking for shoes that look like this for over a year.
