These are light-up shoes for girls. The size marking on the insole has disappeared, but they are 19cm. They show signs of wear and have some stains that can't be removed. The sides light up with vibration, as shown in the 2nd and 3rd photos. They still light up now, but I don't know how much longer they will. Please be aware of this. They sparkle and are very cute! How about them for a spare pair or for playing in?
