I like these boots for the most part. They feel high quality and like they will last me several falls and winters. The heel fits a little loose in part due to to the fact that the zipper is on the back. The zipper also bulges out a tiny bit at the heel - not a big deal and I don't think anyone else will actually notice. I have 15" calves and these boots fit perfectly snug around my calves. I think someone with slightly bigger calves would still fit in these since there is a large elastic patch. However, the elastic is very stiff and tight and probably only gives about an extra inch. These are comfortable and don't take much breaking in. Contrary to other reviews, my boots do stand up on their own and the leather is soft but not flimsy. Nice purchase, especially if you catch them on sale :)
