Cressi Rubber Fin Keeper

The simple things in life often turn out to be the most useful and Fin Keepers are a perfect example. Their benefit is great especially if your foot pocket fits a little loose. They are a simple, inexpensive concept that works great, they last for years, yet rarely mentioned. Fin keepers keep the foot pocket tight against the heel giving the diver full fin power. You can’t truly appreciate them until you use them. When you do, you will notice the difference in power instantly. By holding the foot pocket against the bottom of the heel they limit or delete lost power. Without fin keepers every time you kick the fin the foot pocket will lift off your heel. Just a ¼” of movement away from the heel will result in major power loss. Power is lost but spent energy is unchanged.
