Tossing something on our feet while surfing can really turn the tide between too cold and being just fine. But if we want to be more than fine, we toss on the 2mm Pro Reef Bootie from Billabong. Its stretchy neoprene, flatlock seams, and mitten-like toe design keep us in complete comfort while riding chilled walls of water. Plus, the grippy outsole helps stop us from sliding like a penguin on top of the board.
