Okinawa Kids is a non-insulated version of its look-alike cousin, Niseko 3.0 Kids. It’s a rain boot, however, not a typical rain boot. With a shell made from waterproof EVA, not rubber or PVC, Okinawa is a much lighter boot than many of its competitors. The transparent outer sole makes it perfectly suitable for use on boat decks or other surfaces that you don’t want to leave marks on. It comes with a felt insole that can be easily replaced.
