Otavia takes a classic seventies disco platform, keeps her curved edges, but halves her into a mule. Her shiny brown leather upper features slits to either side of the foot and swoops down to a rounded square toe. Her rubber sole is bold and robust, carved into the welt to define her figure, built with memory foam insoles for added comfort. Materials Upper Material: Natural Cow Leather Lining Material: Leather and Synthetic Leather Rubber Outsole Designed in London. Made in Portugal.
