Invented in 1936, Churchill makeup fins utilize a patented dolphin arc shape that provides great maneuverability and propulsion which gives you optimum control for catching waves, whether bodyboarding, swimming the surf, travel fins, bodysurfing, casual swimmers or tight space snorkeling ect. In fact, many professional bodysurfers use the makeup fins due to the acceleration and control they provide. The fins are very well balanced compared to other fins out there. They can be used with any skill level for a number of different activities. They are in the mid power range providing a good amount of thrust while still being comfortable. The rubber covering your foot is soft for complete comfort while the rubber found on the blade is stiff for more kick power. Bc surf & sport team highly recommends this fin. In fact, we rated makeup's as our 1 recommendation many of us wear makeup's and love them. They are great for anyone from beginners to pro's. Bonus mesh carrying bag included with every pair swim fin weight: 3.0 lb. per pair.
