cressi pro star fin black: Designed to be used for Scuba as well as Snorkeling, the Cressi Pro Star is the perfect choice for the Recreational Diver. This is a Futuristic Design, deriving from the Cressi Deep Sea Skin-Diving Models, which introduces the use of more Reactive Materials. The Blade is made of Exceptionally Light and Reactive. The Blade Material is combined with a Comfortable Thermo-Rubber (elastomer) for the Foot Pocket, Side Rails and for various Inserts. The Blade Originates from the Upper-Part of the Foot Pocket, with a 20% Increase in Useful Surface Area compared to a traditional fin of the same length. The Side Rails extend along the Blade, continuing in a Protective Seal around the whole Blade Edge. Two Stabilizing Flaps on the End-of-the-Blade and on the Sole of the Foot, guarantee Excellent Stability of the Fin during Kicking.
