Keep your feet warm and protected while scuba diving with these comfy 5mm neoprene boots. The name comes from the exclusive design of the sole that features a system of drainage grooves (DS Draining System), which prevent the suction effect between the boot and foot pocket. Wearing these also makes donning and doffing a fin much easier. Theyre also great for snorkeling, kayaking, and surfing—or any other water sport! Great for those who have to cover large distances on foot to the dive site. Two year limited warranty.
