PROLIGHT is the successor of the mythical Frog model from which it inherits its fundamental characteristic that extends the blade over the foot pocket, but applying new materials and an improved design. The result is a medium-sized fin, with surprising reactivity and great propulsive performance.
The lightness and balance of the materials, combined with a very modern design, make the Prolight a generous fin, which provides exuberant performance with limited physical wear. Very versatile, it is ideal for both the novice diver and the professional or technical instructors and divers.
The blade is born directly from the upper part of the foot pocket, joining the fin to the foot and transmitting all the effort generated by flapping without loss of energy through the soft areas. This format allows the water to be channeled from the same ankle to the final edge of the blade, unlike traditional models, in which the foot pocket has no contribution to advance. In addition to improving the directionality of the flapping, this design provides performance between 10% and 15% higher than those that would correspond to the fin due to its blade surface.
The combination of 3 different materials guarantees the optimization of the requirements of each area of the fin:
Polypropylene main body: this material, inherited from apnea fins, has as its main characteristic the very fast transmission of the applied energy and its great structural rigidity. It is applied to the upper and internal area of the sandwich of the sole. It is very nervous and reactive and facilitates a very agile and effective flap. It has an effort-performance ratio clearly superior to traditional materials (natural or thermoplastic rubber, polyurethane, EVA). It also has a great resistance to breakage to the point that Cressi guarantees it for life for sports use.
Flexible elastomer: applied to the foot pocket and areas that require flexibility and elasticity, as they influence the diver’s comfort: toe of the foot pocket, inner sole and instep area in contact with the ankle. The fusion of both materials is carried out at the molecular level and its solidity is guaranteed for life for sports use.
Longitudinal section “spina di pesce”: this concept, inherited from apnea fins, implies that the blade has a decreasing thickness as it approaches the tip. In this way, the recovery of the bow, which the flapping induces in the fin, causes a “whip” effect when the blade recovers. In addition, it makes the bending of the fin much more progressive, improving the directionality of the fin.
Foot pocket in three different volumes, with the central area narrowed so that the foot remains firmly fixed inside and the transmission of the foot / foot pocket / blade effort is direct and precise.
PROLIGHT is an excellent combination between:
Power: thanks to its fairly rigid longitudinal composition.
Speed: thanks to the performance of polypropylene.
Use of effort: thanks to its materials and the decreasing thickness profile
Handiness: given its moderate length.
