The Rondine Free Frog, one of the recent additions to the Cressi-sub family of quality products, is already one of the most popular fins in the Cressi-sub line. With the innovative foot pocket below the blade design, the Rondine Free Frog maximizes kicking efficiency by increasing the amount of usable blade surface area. And, because of a more perfect alignment of the fin blade, the stress on the leg is minimized without sacrificing power. Extensive research of human anatomy and fin design has proudly gone into the development of the Frog family of fins. The soft foot pocket material makes for an exceptionally comfortable fit, while the rigid, flexible material in the blade makes the Rondine Free Frog a winner. The Rondine Free Frog was primarily developed for use by trained Scuba divers, yet it had received wide acclaim from snorkelers and free divers.
