Thank you for viewing. Used a few times. I am selling it because I no longer use it. ■ For marine sports and leisure activities such as diving, snorkeling, and fishing! ■ Neoprene material Made of the same material as wetsuits, it has excellent elasticity, water repellency, durability, and heat retention. ■ Excellent heat retention High heat retention prevents body temperature loss. ■ Non-slip processing Non-slip processing is applied to the toes, heels, and soles. ■ Easy to put on and take off The shape is not easily deformed, so it is relatively easy to put on. ■ Product Description Size: M Sole: 24-26cm Color: Black Material: Neoprene Fabric thickness: 3mm
