Thank you for viewing. These are M-size waterproof shoes with jewels. According to the description, they are waterproof for 4cm for 4 hours. They are slip-resistant on rainy days and easy to put on and take off, so I was planning to use them instead of rain boots. I used them once for a day. The materials are polyester and aluminum. Made in Japan. The black shoes have beads and a very stylish design. If you are interested, please consider them. Thank you very much.
