Thank you for viewing! These are sneakers with a Frozen design. How about them for a spare pair for your child, who will quickly outgrow their shoes? They light up with the vibration of walking. The heels light up. The batteries are not replaceable. Operation has been confirmed. They were only worn for a few months. They were worn by a child, and although I cleaned them after they were last worn, there are some stains that won't come off. I plan to ship them as compactly as possible. Please understand that these are used items that a child has worn. Thank you!
