Like with all JUMP shoes, these boots run half a size small. I, like other reviewers, found this boot snug around the calf, but lucky for me, I can zip these up over my pants. If your calves are small enough to wear these comfortably, they are really nice. (My calves are ~14 inches in circumference. Probably an ideal boot for juniors or petites like me.) I like their slender profile and the cowboy-boot-style toe. The details are subtle and I like the color a lot. I can wear thick socks with this boot, and the ankles are actually very roomy. Be aware that this boot shaft will reach the widest part of your calf. It's not quite tall enough to hit your knees. I love this boot so far, and have worn them all day at work without problems.
