The Ibiza 3mm are lightweight boots ideal for outdoor sports and travel. They are suitable for surfing, kayaking, scuba diving and a variety of water sports. Made with super elastic neoprene, these boots are built to provide maximum comfort and durability. The back of the heel has been specially designed to fit perfectly with open heel fins for scuba diving. The small ridge is used to prevent fin straps from slipping. A strong non-slip molding covers the entire sole. Rinse with clean water after use and let it dry.
