I am very happy with these boots. I had never owned a pair of knee-high boots before (I mean, in my adult life!) and was nervous about buying a pair on-line without trying them on. But these boots are great! Very comfortable to wear all day, warm but not too hot, and they look nice with a skirt or dress, with or without tights. They fit a little bit big in the foot, but that's good so I could wear them easily with thick socks; and my foot doesn't slide around if I just wear thin socks/tights.

They also fit perfectly around the calf. I can't wear them with pants tucked in, but I was planning to wear them with skirts anyway, so I like them fitting this way. The reported measurement around the calf seems accurate.
