I really liked these boots online but was a bit skeptical because I have large calves (17"). I picked them because they had adjustable lacing AND a zipper that went the full length of the boot. I had tried numerous boots that said were for larger calves but always had to return them because they didn't fit. These fit wonderfully. I was able to unlace them 1 time to fit to my calf and have only needed to use the zipper since. I wanted to be able to wear a thicker sock so I did return them for a 1/2 size larger since they fit perfect with thin socks. I would say they are very comfortable and pretty much true to size. I have worn them tucked in with skinny jeans and also with leggings and a skirt and they looked great.
