Da FIN Swim Fins
Self-proclaimed "World's Best Swim and Surf Fin" but with good reason, Da FIN is an open-heel fin that is the official swim fin of the United States Lifesaving Association. These fins are arguably the most durable on the market as they are capable of handling the most rugged surf with relative ease. The side rails on Da FIN angle halfway down the blade to force the fin to bend at a critical point for optimum acceleration. The v-shaped foot pocket and the rigid blade work together to create more thrust per kick for maximum acceleration. This innovative design allows Da FIN to be surprisingly powerful for such a lightweight fin. Another added benefit is that as there's no left or right footed fin, they can be interchanged between each foot. If Da FIN is good enough for lifeguards to use then it shouldn't be overlooked.
