A classic from the Cressi range, on the market since 1993 and with a huge number of fans in every corner of the planet. The fin is made from a clever combination of a robust polymer and a soft elastomer, the latter used for the foot pocket, the stringers and some inserts.

Frog was the first Cressi model to use the "foot pocket subjected to the blade" design.

The blade originates directly from the upper part of the foot pocket, solidly joining the end to the foot and transmitting all the effort generated by the kick without the loss of energy through soft areas. This system allows the water to be channeled from the ankle itself to the final edge of the blade, unlike traditional models, in which the foot pocket has no contribution to the advancement. Improving the directionality of the kick.

The computer-designed foot pocket is particularly comfortable and ensures optimal transmission of effort during finning.

The FROG is heavier than equivalent Cressi models of recent design, but this feature means that it can be used with dry suits or thick suits thanks to its great thrust power.

It is a fin much appreciated by professional work for its robustness and comfort, even after hours of use, as well as by diving centers, who appreciate its versatility and practically infinite duration.
