Fins are a diver’s primary source of propulsion, and choosing the right pair should be a careful process. Divers looking to do a lot of tropical diving generally favor lightweight equipment, making full foot snorkel-style fins attractive. However, rocky beaches can make entry a painful endeavor without proper foot protection. Technical divers love heavy, negatively buoyant fins like the Hollis Batfin, Apolis Biofin, or the Scubapro Jetfin for their bullet-proof construction and weighting that favors an upright dive position. The everyday California diver, however, will find most open-heel medium weight fins to be more than enough for their purposes, so feel free to choose something that suits your style. Remember, looking cool is one of the most important parts of being a diver, so "it looks bad ass" is a completely legitimate criteria for your fin shopping.
Spring Straps: Most open heel fins are compatible with spring straps, which makes donning and doffing much quicker and easier, as well as improving a secure fit. These are especially useful during intense, wave-heavy beach entries where good timing is the difference between a smooth entry and a major wipe-out.
