I bought these in a size 9 after reading here and there online that they were a good pick for large calves.  I was hoping these would fit my 17.5" calves, but no way, not even close.  The inside of the boot (where the foot slides in) was also so tiny that I had a hard time getting my foot in there at all, even though the boots were half a size larger than what I usually need. It actually felt like I was trying to put on children's boots.  They did look absolutely gorgeous and well-made though, and I am very sad that they did not fit me.  So yeah, if you're looking at these as an option for large calves, I don't recommend them at all.
