Smokin' in the Water
What do cigarette companies have in common with fins? It wasn't long ago that everyone smoked tobacco, everywhere. So great were social influences that the military issued cigarettes to our soldiers. Those who were health consciousnd did not smoke were the odd person out.
You see terrestris fins everywhere. Terrestris fins are those that enclose your foot like a shoe or extend off the end of your foot. If open heel they require a heel strap or they will come off when you kick. They are among those still issued, whether due to habit or cost, to new divers in the US military. Once a diver graduates into Special Forces then their fin choices expand to include Force Fins. Terrestris Fins are not the best to use. They might be the fins you are wearing in the water today.
Force Fins have "an open foot pocket, that allows the wearer to wiggle their toes, and cantilevers the force of the kick from the large muscles of the upper thigh." Wikipedia, swim fins, Force Fins.

Multiplicity - many companies and stores - selling virtually the same design influences social behavior. You are familiar with the look of a shoe and a paddle extending therefrom. You want to feel part of the pack. Your purchasing decision is based upon that familiarity. That is what the mass merchandisers depend upon in keeping you hooked on their easier to manufacture terrestris fins.
Force Fins are handcrafted in the USA by one Company, and only one Company. Its original founders still handle each and every pair that leaves their Santa Barbara warehouse.
