These are black boots, size M. I like the style and bought them at a store. I wore them a few times the year before last, and last season I was pregnant, so I stored them in a shoe closet with a dehumidifier. The size is listed as 23.5cm, but I usually wear shoes that are 23-23.5cm, and I chose this size accordingly. The product itself is labeled as size M. There are no stains or mold. The soles are worn from use, but not excessively, so they may not be very noticeable in the photos. I will take waterproof measures when shipping. If you need any other photos, please let me know in the comments. If they don't sell, I will dispose of them at the end of the year.
