Crocs size 11. This is equivalent to 18cm in Japanese size. I used these for about a year. There are black marks left where I attached Crocs Jibbitz accessories to the holes. I wore these almost every day, so there is some wear on the soles and various stains that won't come off even after washing, but I think they are still wearable. They have been home-cleaned, but these are used children's shoes, so please check the photos carefully before purchasing. Color: Pink系 (Pink-based) Strap: With strap Season: Spring, Summer, Autumn, Winter
