These are Hiraki amphibious shoes. I bought them about two years ago and wore them 3 or 4 times. They are clean with no noticeable stains. They are fluorescent yellow mesh kids' shoes with Velcro closures. They fit snugly, so they didn't come off even when splashing around. There are also insoles for size adjustment. When I put them on a child who wears 17cm sneakers, they fit just right with two insoles, so they might be a little big. Please consider this as a reference, as it may vary from person to person. - Color: Fluorescent Yellow - Size: 17.0cm - Design: Mesh material - Sole: Black rubber sole - Closure: Velcro - Usage: For water play and the beach There are two insoles for each shoe, left and right.
