• High-quality material: The diving socks are made of a high-quality 3mm neoprene and nylon blend, soft, flexible, highly elastic, quick-drying, and durable, with excellent thermal performance. • Foot protection: Neoprene socks offer excellent warmth and protection, effectively slowing foot temperature loss and being very durable, they can protect your feet from sharp rocks, shells, coral, and jellyfish stings. (Note: The diving socks are not fully waterproof, but rather a diving gear for neoprene overalls.) • Non-slip design: The bottom sole is designed with a non-slip silicone rubber pattern, providing excellent grip and exceptional traction while diving or other water sports, even when walking on wet or sometimes slippery surfaces. • Multiple sizes and elastic hook-and-loop closure (size/shoe length/sole length): M: 40-41/23-23.5 cm; L: 42-43/24-24.5 cm. In addition, we've designed a hook-and-loop closure at the opening of the diving socks, allowing you to adjust the waterproofness to your needs. • Widely Suitable for Water Sports: The high design prevents sand or other small objects from entering, making these beach socks suitable for men and women and for various water sports such as diving, snorkeling, swimming, surfing, rafting, boating, kayaking, beach, sailing, etc.
