Wakeboard bindings. Free size. They are the type that tightens with the front laces and heel lever, and because they are open-toe, the toe area is wide, making them very easy to put on and take off even for those with large feet around 30 cm. As far as I know, the wire lock system is rare in models where the boots/bindings are integrated, and I think it's a rare model that's hard to come by. However, the lever wires have rust and are slightly frayed, so they will prick if touched with bare hands. If you can replace the wires, we recommend replacing them before use. In addition, the plating on the metal fittings that attach to the board is considerably corroded, and there are also places where the fabric is starting to tear due to aging, but overall, they are durably made, so they can still be used by those who don't mind. Please read the above precautions carefully and only purchase if you understand them.
