I am 5'11" and so not really a boot-wearer...at all.  In fact, this is my first pair of boots, and only because I saw these at a running store of all places and instantly fell in love with the look.  The only problem was that I couldn't find my size in this color anywhere (9.5).  When Amazon dropped the price of the size 10's down to $85, I decided I would give it a whirl.  They do not disappoint!  They are SO comfortable, especially for having a pretty good heel and being a 1/2 size too large.  And I received a ton of compliments, which always helps :)  These are buttery soft, good quality leather, with faux fur lining that makes it extra comfortable.

Here is what I don't like too much:  these are definitely not knee-high, especially if you're long-legged.  They hit about 3/4 up my calf, but they are cut to allow for calf muscles LOWER down...so they are wide where my calf tapers down toward my ankle.  It's really not that noticeable, just kind of weird.  I have medium to thick calves and these fit just perfect.
