I have a difficult time buying boots(especially online)because of my calf size. However, after reading the reviews I decided to give these a try, and I am super pleased! They fit my calves very comfortably and they are comfortable enough to wear all day. When I first put them on they seemed a little stiff and was a bit concerned about wearing them for the entire day. Much to my surprise, after wearing them for 9 hours (I teach so I stand all day long) I wasn't in any hurry to get them off. They broke in rather quickly. Great heel height, fit my calves, comfortable enough for a long day of wear, and looked great with some tights and a sweater dress. In fact, I am wearing them for the second time today with jeans. So, versatile as well.
