Nike Kids' Sunray Adjustable Sandals The size has worn off, but I'm fairly certain they are Size 5Y (you just barely make out 4.5 UK which would coincide with 5Y US) These sandals were worn very little before they were outgrown. They are in great shape, and are very durable sandals. Pet and smoke free home. Fabric upper in an athletic sandal style with an open toe Adjustable hook and loop closure straps for an easy and secure fit Smooth lining with a contoured comfort footbed Foam supportive midsole Durable rubber traction outsole
