These are Nike Aqua Sock 360s. 13cm *Sizes 12, 13, 14, 15, and 16 cm are in stock. *We also accept bulk purchases, so please comment if you are interested. These are slip-on type shoes that can be worn for water play, light outdoor activities, or as sneakers in spring and summer! They are also great as an alternative to sandals! These shoes are designed to let you move around while splashing in the water. The mesh upper securely covers little feet and keeps them comfortable. The grooved rubber sole provides excellent traction on wet surfaces. They are often sold for over 5,000 yen online, so this is a great deal(^^) They do not come with a box. If you would like the box, it will be an additional 500 yen. Please understand. Thank you!
