Purpose and key benefits 3mm neoprene diving socks that improve comfort, warmth, and protection during water sports. Anti-slip sole design increases traction and stability on wet surfaces and inside fins. High-elasticity neoprene provides a snug, comfortable fit that reduces chafing and keeps heat close to the skin. Material and performance Made from 3mm neoprene for thermal insulation and flexibility. High elasticity allows easy on/off while maintaining a close fit to minimize water flushing. Anti-slip sole pattern enhances grip for safe movement on slippery decks, rocks, and pool edges. Function and compatibility Designed for use with dive fins or as standalone water socks; compatible with common fin styles and open-heel or full-foot setups. Lightweight construction works under wetsuit booties or alone for quick-entry activities. Durable neoprene resists stretching and retains insulation after repeated use. Practical use scenarios 1. Scuba diving or snorkeling: wear the socks under fins to reduce foot rub, retain warmth in cool water, and improve fin fit. 2. Surfing and paddle sports: use for toe protection and added traction when entering or exiting surfboards, paddleboards, or rocky shorelines. 3. Beach and pool activities: slip them on for quick protection from hot sand, rough rocks, or slippery pool decks. Care and fit suggestions Rinse with fresh water after use and air dry away from direct sunlight to preserve neoprene elasticity. High-elasticity construction accommodates a range of foot shapes; choose your normal water-sport sock or boot size for best fit. This product combines 3mm neoprene insulation, high elasticity, and an anti-slip sole to deliver warmth, protection, and secure footing across diving, snorkeling, surfing, beach, and pool activities.
