Comfort, durability and convenience are our top priorities in booties and water socks. Water resistance and drainage considerations go into every design decision. In manufacture, we use quality materials like Nylon II neoprene, breathable Lycra mesh and vulcanized rubber. The YKK #10 and #5 zippers are done in chunky, corrosion-proof, impact resistant plastic with large pull tabs. Elastic neck booties and socks are super-stretchy for easy donning and doffing.
