I bought this boots because I need nice comfortable black boots. I couldn't be more please they arrive right on time. They run true to their size. They are around 17.5 half inches from the hill to the top of the boot which I absolutely loved. The leather is so soft and the zipper in the back looks gorgeous. These boots don't have a zipper to open them. Just put them in and out, when I first saw them I thought no way they are going to fit me I have big calfs. However, they fit me perfectly I wore them with heavy socks no problem at all. I have a pair of frye's and I loved them but this boots are more comfortable than my frye ones.
