Unfortunately I received a pair with a defect :(  The boots are pretty comfortable at first but after wearing all day my foot was sore in the heel/arch area. My instep is pretty low so that might just be a problem with my feet. ;) or maybe I should order a half size down. The reason I had to return them was one boot had a large gap between where the heel meets the sole. This caused the boot to squeak. I didn't realize this until I wore them to work. Fortunately Amazon was awesome and I was able to return the boots! I'm still thinking about ordering another pair in a half size smaller because they looked so good on me! :)  This height was great for my skinny calves.
Update: ordered the next size down and the heel is still very uncomfortable to me. Had to send them back and give up on this boot. :( Cute but not worth the discomfort.
