These knee-height boots are perfection! They are black faux suede and feature a gold outsize zipper with buckle details both at the top of the calf and around the ankle with a quilted patterned back. The inside of the boot features a black working zipper that makes for putting your boots on hassle-free! The calf is 6" in diameter and the heel rise is 1.25". The front of the boot is about 2" higher than the back of the boots. They are super comfortable and versatile! They run true to size- April usually wears between a 9 and 10 and she preferred the fit of the 10.
