This listing is for 4 pair of Nine West Oaks Kitten heels in a size 5.5. These are leather! Red, navy, black, and black alligator are included in this set. heel hight is roughly 2 inches (see photo). These shoes are in pretty good shape. See pictures for accuracy, as the black ones have some scuffing on the heels and wear shown on inside heel. They have not been worn in 9 years and have been sitting pretty on my shelf up until now.
