Heel height: 1 inch. Shaft height: 5 inches. The heel height is measured from the outer back of the visible sole. This measurement contributes to the overall height, but it does not reflect the elevation itself. Footwear with a shorter heel height will appear more subtle. What is the method for measuring the shaft? We calculate the shaft height from the footwear's base to the upper edge of the collar or the highest point. Thus, a low-top design will result in a reduced shaft height.
