ALDO MATERIAL: Faux leather SIZE: 41 (11” inches, toe to heel) HEEL: 4” SHAFT CIRCUMFERENCE AT TOP: 7 1/2” SHAFT HEIGHT: 23 1/2” Cleaning out my closet. The shaft of these boots does have some stretch to it, and has a bit of a grip on the top, to help hold it up. The inside of the shaft has a soft, velvety feel, so very comfortable to wear.
