Heel height: 1 inch. Shaft height: 5 inches. Heel height measurement is taken from the visible outer back sole. This does not refer to the elevation but adds to the overall height. Styles with a shorter heel will be less noticeable. How do we measure shafts? We measure shaft height from the bottom of the shoe to the top of the collar or highest point. Therefore, a shoe with a low top will have a shorter shaft height.
