I ordered this in taupe because they were inexpensive and looked like they'd be a cool neutral knee-high boot.  They arrived lightning fast, however the left boot did NOT want to fit my upper calf.  The right boot fit great and looked great.  Maybe my left calf muscle is larger or something because I actually had to try and stretch the top of the boot out to get it to finally pull up all of the way.  As others have mentioned, the lower part of the shaft is huge, and I had to pull the laces as tight as they would go to get a comfy fit.  They're warm boots, with nice flannel inside, and I wore them all day at a comic book convention with no problem.  They do feel flimsy/cheap as compared with other knee-high synthetic boots that I've purchased, but once they're on, they looks fine.  They're hard to pull over leggings and jeans because of the flannel lining and because of the narrow fit at the top.  I finally got annoyed with the left boot and cut a notch in the back by the loop used to pull the boot on.  That gave it just enough room to finally fit.

If you have muscular calves, I wouldn't buy these.  You'll have problems!!
