I shopped online and in many stores for a great equestrian style boot.  I am small, have thin calves, and so many boots gap too much or look like rainboots on me.  These did not.  The shaft is part soft fabric for a perfect fit with tights or leggings. Great, sleek look - a nice tall boot that hits just below the knee.  True to size and that Nike Air footbed makes for an immediately comfortable fit.  There is no zipper but they are easy on and off because of the fabric.
