Pluma is an extraordinary fin that makes the most of a sophisticated molding technology previously used only on the hi-tech models designed specifically for free diving and scuba diving. In fact, it uses the same Cressi patented construction system of molding in 3 different materials to get high performance, extreme lightness and easy kicking, and astonishing comfort. The blade is made from light and at the same time reactive polypropylene, with a very energetic and snappy rebound. Two side supporting grooves and other ribbing on the bottom of the blade guarantee progressive and controlled bending. The result is powerful and fluid, untiring kicking, just like a fin in this category should provide. The foot pocket extends right along the bottom of the blade to guarantee high protection during kicking even in shallow water and near rocks and suchlike. It is made from soft thermo-rubber and the computer-designed shape offers great comfort as well as making them suitable for long use. The entire sole is hard and comes with large non-slip inserts, both for total protection of the foot and for excellent transmission of the leg-fin effort. A brand-new construction technology of futuristic rotating, dual-injection molds means two different materials can be molded at the same time, keeping production costs to a minimum, to the advantage of an unbeatable price-quality ratio.
