A fin with a novel conception in terms of materials and design but that enjoys the exclusive characteristics of the Cressi diving fins while maintaining the spirit of the legendary Frog.

FROG PLUS is manufactured in a new variant of low modulus polypropylene that, together with a particular structure, combines great flexibility, softness and resistance to demanding use (including as a rental fin and school in a diving center), durability and an unprecedented aesthetic in fins designed with this philosophy. Frog Plus is the authentic 4×4 of the Cressi fins.


The combination of 3 different materials guarantees the optimization of the requirements of each area of ​​the fin without the need to increase thicknesses:

Polypropylene main body: a material inherited from apnea whose main characteristic is the very fast transmission of applied energy. 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 flap and a vertiginous advance. It has an effort / performance ratio clearly superior to rubber (natural or thermoplastic), polyurethane, E.V.A. and second only to carbon. Likewise, it has a great resistance to breakage to the point that Cressi guarantees it for life for sports use.
Flexible elastomer: It is applied to the foot pocket and areas that require flexibility and elasticity, since they influence the comfort of the diver, the toe of the foot pocket, the inner sole and the 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.
Compact elastomer: Flexible but not elastic. It is applied to areas that require a rubbery, non-slip but firm and highly resistant composition, longitudinal ribs, foot pocket sole and foot support band (located in the middle area of ​​the instep). It is also assigned to areas that require non-slip capacity, inserts in the sole (zone in contact with the ground) and anti-shock, such as the perimeter reinforcements of the upper.
Technical characteristics

The structure, studied for this new variant of the base material of the blade, aims to combine great strength with good water channeling, protection of the lateral ribs and a soft toe for comfortable flapping and less erosion action due to accidental contact. with the background. It also uses several technologies common to the rest of Cressi models.
“Foot pocket under the blade” design: the blade arises directly from the upper part of the foot pocket, solidly joining the fin to the foot and transmitting all the effort generated by flapping without loss of energy through 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.
Thickness of the blade with a decreasing profile to improve the directionality of the fin and achieve greater inertia of the final part of the fin.
Footwear reinforced in the upper area by an additional thickness and laterally by two polypropylene extensions from the upper to avoid the dispersion of energy in the process of transmission from the foot to the upper. Its three long volumes fit the foot comfortably but firmly optimizing the use of effort.
360º pivoting buckles, with bayonet insertion in the foot pocket that prevents accidental loss of the female part. As an option, there are spring straps (AISI 316 steel) with buckles identical to the standard version but reinforced with the stainless steel pin.
