Purchased these recently and truly love them.  Ok, they are more of a casual boot, but they are thick leather and feel well made.  I am a 6.5, and that is what I ordered...they are a bit loose around the heel, but if I ordered the 6 they would have bothered my toe...so I say they are true to size.  As far as the calf circumference...it is not 13.5"  like the description says.  I would say they are more like a 15" circumference.  I have 14" calves and these are easy to pull on over my skinny jeans, with space for a finger to spare.  They are not floppy boots, so they stay upright with no scrunching, and have a nice tapered cut at the top. They were a bit stiff to walk in as the sole is not very flexible, but I think with wear that will get better.  Not super comfortable...wish they had a bit of cushion in the footbed, but may try an insert.  My only true negative is the dark brown leather has a bit of a dusty appearance.  I don't know how to accurately describe it, but it wasn't pronounced enough for me to send them back.  I am hoping with time and wear that the leather will petina a bit.  All in all, I really never would purchase a pair of boots for this amount of money, but when you find what you want, it is hard to settle.  These are really cool boots and plan on wearing them for years to come, so they are worth it.
