I bought this a few years ago, but my child has outgrown it. It's made of thin fabric, so I think it's suitable for indoor use. My child used it for playing ninja. It has been washed, but there is noticeable dirt on the back. Please check the photos. There is also some slight dirt inside. Therefore, I am selling it at a low price. Returns are not accepted. If you have any questions before purchasing, please ask in the comments. When shipping, I will fold the ankle part. Tabi Tabi Tabi Festival Tabi Ninja For children Indoor shoes
