I wanted so badly to like these boots except the shaft was a little too saggy and loose for me. They bunched up quite a bit around the ankles and then had a large gap around the upper part of the leg opening that looked a little funny. I don't have what you'd call "skinny calves" - my diameter measures 14cm at the widest point. The material is also the type that will scuff and scratch at the slightest touch. I ended up going with Frye boots that were much more expensive but had a much better fit.
