Thank you for viewing. I am selling these because my child has outgrown them. These are SUN series sandals from Méduse. Perfect sandals for the pool, beach, and outdoor activities. They are water-resistant, quick-drying, and breathable, making them comfortable to wear barefoot. Stylish sandals made with sparkling silver sequin material. They look great with socks and various outfits. According to the official size chart, the size is 31 (18.6cm). Please understand that these are used items before purchasing.
