NOTE: As of 2012, Churchills are no longer made in Malaysia. They are now manufactured in China, so the rubber composition is softer now. Invented in 1936, Churchill MAKAPUU floating FINS utilize a patented dolphin design which gives you optimum power and acceleration for catching waves. Makapuu fins also act like a skeg on a surfboard to help maintain total control. The rubber covering your foot is soft for complete comfort while the rubber found on the blade is stiff for more kick power.
