The color is black, and the size is UK3.5, which is 23.0cm. It has a zipper, making it very easy to put on and take off. To ensure the next person who wears them can do so comfortably, I will clean the shoes as much as possible with a cleaner, disinfect them, and send them in a new box. Please refrain from price negotiations. I don't have a good impression of the price reduction requests feature on Mercari, so I will refrain from responding even if I receive a request. Thank you for your understanding. Color...Black系 (Black-based) Material...Genuine leather Stains, tears, odors, etc....None
