The key phrase is "Duckfeet style fins"
There is only one Duck feet fins, (duck foot?) and those are the ones designed and manufactured by Arthur 'Bud' Brown in Laguna Beach, later Huntington Beach. He sold to Ken Norris of Pacific molded products (PMP) in 1960 who continued producing the original ducks under Brown's Swimaster label.
PMP sold to Voit around 1961 who for a while used the Swimaster name and product line as their professional line.
Voit people changed the compound from pure gum rubber to black neoprene and stated the downward spirl of Duck feet.
Over the years there was many companies with designs that attempted to duplicate ducks, but were just a little off the mark. S/W 707, Imperials, US Divers Aqualungs etc looked like Ducks but missed the mark in comfort and performance.
If the diver was kicking corrrectly the ducks were noted for rubbing the top of the toes RAW! After several months the toe skin was like elephant skin and the diver would dive in comfort-with thrust to spare-but if he did not dive regularly the elephant skin disappeared and the process started all over again.
Over the years of Duck feet production there were a number of fin performance test performed. The frist was by Captian Walter Mazzone, USN in 1950 (?) on USN divers, then 1955 (?) Bill Barada on Sport divers, and in 1965 by Tony Christensen for his UCLA doctorate with a variety of subjects in size weight and experience. In all the test the ducks out performed all other fins.
Tony's was the most accurate and conclusive. He constructed a huge UW test bench which measured air consumption, thrust; maximum and sustained, etc etc. The best performing fin was the straight blade stiff fin (aka Ducks). A distant second place was a curved blade stiff fin (aka Aqua Lung)
Therefore, they may look like a Duck but they are NOT Ducks! There IS a difference.
