The color is beige or a beige-gray, with small rhinestones scattered throughout, making it fashionable. Please check the images for the color. Please note that the actual color may differ. Please refrain from purchasing if you are concerned. These slip-ons are easy to wear and have a design that is easy to match with clothes. There is no material label, but the overall feel is suede-like, and the inside has some cushioning. In terms of season, it seems like they can be worn almost all year round, but this is a personal opinion. 23 centimeters These shoes are from the shop Marina. I have too many shoes. They are unused and have been stored, but since I purchased them from the store, there are some slight stains on the back of the heel and the edges. I only tried them on at the store, but they have been stored at home. Please refrain from purchasing if you are concerned about this.
