I'm selling these because my child has outgrown them. I purchased them new from a select shop (authorized retailer). There's no size listed, but the length from toe to heel (longest point) is 21.5cm. The ankle strap tightens around the ankle. The belt is also sturdy, providing good stability, so they can be worn securely. I've worn them a few times. I washed them with shoe detergent, then dried them in the sun and stored them. I think there are no noticeable stains or scratches, but please forgive any oversight. Please check the condition in the photos. There are no smokers or pets. They will be shipped without the box and with simple packaging.
