Purchased last month and only used once! As far as I can see, there are no stains or noticeable scratches, but please refrain from purchasing if you are sensitive to such things. Please refer to photos 2-4 for details! The middle of the insole has cushioning. It's a size M, but it fit perfectly for someone who usually wears a size 24.0 shoe. honeys COLZA COLZA (brand name) Honeys Sandals Size M Color: Ivory Snappy/Casual style (lit. "snappy系")
