Thank you for viewing. The navy blue part is waterproof. It has been used to some extent, but it's a little too small for me, so I'm selling it because I bought different shoes. About this product: Sole Material: Rubber Outer Material: Rubber/Polyurethane (PU) Closure Type: DISC (Dial type) Water Resistance Level: Waterproof These shoes offer a high level of fit. Upper: The upper uses "EXO SHELL," a 3-layer structure with moderate softness that fits various movements and provides waterproof functionality, offering a comfortable fit.
