Brand: ALFASPIN. Material & Specifications: Slip-on shoes for women made of thick genuine leather. The soles have been treated with non-slip processing, so I think you can wear them regardless of the season! They have a sturdy construction, like men's shoes. Marked Size: M. For listing purposes, I've listed them as 23cm, but please consider this based on the marked size. I usually wear 23.5cm shoes, and the design is good, and the slip-on type is convenient for taking them on and off, but I think they are more suitable for someone who wears 23cm rather than 23.5cm. These are used shoes, so there is some wear and tear on the outsole, but they are made of sturdy leather, so I think you can still wear them for a while. Please refer to the images for the condition of the heel wear. If you have any questions, please ask in the comments and understand before purchasing.
