Just received my boots and so far, am very happy with the fit. Good toe room and best of all: they zip up! Those with larger calves know what a problem this is. I was expecting to need the double zipper feature to accomodate my calves, but with thin leggings/socks, no problem and they even have a little space. Not too tight at all. Jeans tucked in may require unzipping the second zipper, but that's fine with me. The bonus is that they are TALL... actually come up all the way up to the top of my calf (something I haven't found in other boots). I'm 5'11" with long legs, and wear a size 11 (sometimes needing a wide width). Some size 11s are too tight in the toes, but these are good. I'd say they fit as expected or maybe even a little big.

For reference, at the widest part of my calf, I measure 17" and from heel to top of calf, also about 17". So that gives you an idea of how the size 11 fits at least. Others have commented that the boots feel big in the heel. I feel that too, but I'm okay with a little looseness there. Worth it for all the other features. Bonus if you need an orthodic/gel support in that there's room in the heel area.

Ordered dark brown and color and finishes are good. Doesn't look "cheap". Also like the rubber sole with traction that you always get with Aerosoles. Will be good for walking in the winter without fear of slipping on light snow/ice.

Overall, very happy.
