These are one of the most comfortable pair of sexy boots that I own. And this is very important because usually beauty is sacrificed for comfort in the heeled shoes I come across. I simply *glide* across the ground with these; they are very easy to walk in. They really are a great fit around my leg and true to size and color (I got the grey). They also act as natural leg warmers. My only complaint is the zipper is somewhat cheaply made and so it's a bit hard zipping and unzipping these, but it's a very minor detail, and they haven't come off the boot so they get 5 stars from me!
A few more details: I'm 5'7'', w/skinny calves and these came up to a little above my knee. They do not slide down when I'm wearing jeans/pants, but they aren't too tight either. Have not tried them on the bare leg yet.

I would certainly recommend these heeled boots to any fashion forward gal!
