Two tone, front of boot is sleek faux black leather, back of boot that wraps around the leg is soft, stretch elastic fabric, which gives a little room for the women with strong legs. Diameter of upper boot is 15 inches with just a pool noodle inside. Very modest wedge heel. Yes I did place pool noodles inside boots, helps boots last longer and maintains shape/structure of the boots. Plus they don’t fall over with noodles inside. Please contact if any questions. Thank-you!
