Made with the exclusive 3-material injection system patented by Cressi-sub, it fully responds to modern diving trends with moderate dimensions and weight and an excellent combination of resistance, power, comfort and aesthetics. The main base of the structure is the use of polypropylene as a material with excellent mechanical performance.
Materials
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 freediving 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 inner area of the sole sandwich. It is very nervous and reactive and facilitates a very agile and effective wingbeat. It has a clearly higher effort-performance ratio than traditional materials (natural or thermoplastic rubber, polyurethane, EVA). 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 the areas that require flexibility and elasticity, since they influence the comfort of the diver: Toe of the foot pocket, interior of the sole and area of the instep in contact with the ankle. It is also assigned to areas that require anti-slip capacity: Inserts in the sole (area in contact with the ground) and anti-shock, such as the lateral ribs of the blade. 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 composition, non-slip but firm and highly resistant: Longitudinal ribs, sole of the foot pocket and support band of the foot (located in the middle area of the instep). This material connects the critical point of energy transmission (the instep) with the nerves in a single piece, avoiding the usual loss of energy through excessively flexible compounds of the foot pocket that produce a slow, heavy flapping that fatigues the instep. .
Technical characteristics
The structure, studied for this new variant of the base material of the blade, aims to combine great strength with good channeling of water, protection of the lateral ribs and a soft toe for comfortable flapping and less erosion action due to accidental contacts. with the background. It also uses several technologies common to the rest of the Cressi models:
"Footpocket design under the blade": The blade is born directly from the upper part of the footpocket, solidly joining the fin to the foot and transmitting all the effort generated when flapping without losing energy through soft areas. This format allows the water to be channeled from the very ankle to the final edge of the blade, unlike traditional models, in which the foot pocket does not have any contribution on the advance. Apart from improving the directionality of the flapping, this design provides benefits between 10% and 15% higher than those that would correspond to the fin due to its blade surface.
Dual lateral ribs, alternating for fully controlled structure and flex.
Thickness of the blade with a decreasing “spina di pesce” profile to improve the directionality of the flapping and achieve greater inertia of the final part of the fin.
Foot pocket reinforced in the upper area by means of an additional thickness and laterally by two polypropylene extensions from the blade to avoid energy dispersion in the process of transmission from the foot to the blade.
Foot pocket with three different volumes, with a narrowed central area so that the foot remains firmly fixed inside it and the transmission of effort from foot to foot pocket to blade is direct and precise.
Quick adjustment 360º tilting buckles. They allow an ideal automatic positioning of the strip during flapping. A new buckle locking system prevents the usual accidental release of the female part.
EBS BUCKLE SYSTEM. +Info
It combines new buckles with an essential and hydrodynamic design, adaptable to all Cressi models, with an innovative self-adjusting strap made of highly elastic pure latex. Latex is the most elastic material in nature and has the property of being able to stretch up to 8 times its length without breaking and with total elastic memory, that is, recovering the initial length. Applied to the fin strip, it gives us enormous advantages:
Reduces the need for sizing as the same strip comfortably covers wide ranges of elongation.
It allows a relation comfort of placement vs fixation of the fin, well above the spring systems, precisely because of its high elastic coefficient (X8 against X1.5 of the spring).
Eliminates the cumbersome need for adjustment of traditional buckles, a process that does not always guarantee the correct fixation of the heel, especially in novice divers or stressful situations during the equipment process.
It allows, while maintaining the comfort of flapping, a high level of pressure on the heel, which is essential to achieve a correct transmission of the energy applied to the fin without loss of energy due to the “spring effect”.
Assimilates the crushing of the neoprene of the boot when descending and compressing the neoprene without loss of fixation.
It is easily replaceable and essential both conceptually and in its manufacture and assembly.
The natural latex used is of the highest quality without fillers that alter its performance and guarantees high resistance to use, saltpeter and sun exposure.
