URBAN RESEARCH Round Toe Plain Short Boots Color: Black Size: 37 These are likely a good fit for those who usually wear pumps in the 23-23.5cm range, depending on the thickness of your socks. I purchased these several years ago and wore them a few times when I first got them, but I haven't worn them recently, so I'm selling them. They have been stored at home for a long time, but I didn't see any deterioration of the material. Please note that there are some scratches on the heel and body of the boots from use. There are also some wrinkles from wear. The soles are slightly worn. The material is, I believe, synthetic leather. These are used items, so please refrain from purchasing if you are concerned about minor details.
