Purchased from the official website. These are Saltwater Swimmers. Size: youth1 (21cm) Price: 9900 *No box included. I'd like to sell these while they're still in good condition, as I haven't had many chances to wear them. I've worn them outdoors 2-3 times with socks. This size is sold out on the official website, so if you're looking for them, please consider purchasing. They are water-resistant, so even if they get wet at the beach, pool, or river, you can just wear them and let them dry. The straps are Velcro, so children can easily put them on and take them off themselves. *Please note that these are used children's shoes, so please refrain from purchasing if you are sensitive to used items.
