Size 10W Width is approximately 18.5cm, but if you need more details, please check with the manufacturer. These are tap shoes that are easy to put on with Velcro. They show signs of use, but I think they can still be used as tap shoes. The "Condition of item" is selected as "Has scratches and stains," so please refrain from purchasing if you are concerned. The discolored parts are not mold, but peeling.
