These are Adidas "AltaVenture" kids' sandals. The color is blue, and the size is 19.5cm. I bought them online but am selling them because I won't be using them. They cover the heel and toes and are the type of sandals that secure the foot, so I think they're safe for water play and outdoor activities. My child has worn a different size of these in the past, and they said they were easy to walk in because of the soft and breathable material. I think they are also recommended for summer outings. When shipping, I will remove the black hook and use simple packaging. I plan to ship via regular mail (定形外郵便).
