These fit my 16.5in calves, but there is a bit of bunching near the ankles.  The small strip of goring give these a nice stretch for wearing with jeans or leggings, without detracting from the look of the leather.  I also like that these have the side zipper for easy on/off access. I'm 5'4'' and the top of the shaft hits a few inches below the knee.  Usually I wear a 7.5 shoe or 8 boot, so I ordered the 8 and they fit nicely. I ordered these boots in the &#34;wine&#34; color, and it's a pretty, flattering rich color.  I think I'll be ordering these in the black color next.
