Swim fins, surf fins, flippers, bodysurfing fins, whatever you want to call 'em the purpose of these puppies is to give you sharp acceleration so you can emulate a dolphin catching waves. Good luck trying to do any backflips though! We stock DaFiNs as they are the Hawaiian lifeguard endorsed fins used by the one and only Mark Cunningham - the best body surfer to have ever lived. They also have a soft foot pocket which makes them very comfy to wear from the start. So do yourself and your feet a favor and get more waves and less chafe today!
