CRESSI Diving fins with rubber strip THOR EBS ABE 155845VAR

Innovative structure that combines two central ribs in high modulus polypropylene and a central zone of the upper in thermoplastic rubber with a convex section, assembled in a polypropylene upper | Two side nozzles to discharge associated negative forces | Channeling and acceleration of water flow, which stabilizes and increases propulsion in relation to effort | Blade pitch increased by 5% for better flapping effectiveness | Medium stiffness | Excellent compromise power-comfort of finning | EBS buckle system with natural latex strap: maximum convenience, comfort and energy transmission.

The new THOR fin has a peculiar and unprecedented structure that combines the two central ribs in high modulus polypropylene, very reactive, and a central area of the blade in thermoplastic rubber with a convex section, assembled on a polypropylene blade. Two lateral nozzles located in the area where the flex begins discharge the associated negative forces and allow the use of two highly responsive ribs. This combination causes a channeling and acceleration of the water flow, which stabilizes and increases propulsion with equal effort.
The inclination of the blade with respect to the foot pocket has been increased by 5% compared to traditional diving models. This angulation provides greater efficiency and a more natural foot position during kicking.
Thor enjoys the exclusive 3-material injection system patented by Cressi, which provides an excellent combination of resistance, power, comfort and aesthetics and 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
High modulus polypropylene: Especially reactive, it is applied to the ribs of the blade and is responsible for providing rigidity and return to the blade. 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. .
It also uses several technologies common to the rest of the Cressi models:
"Footpocket design under the blade": Now increased its angle by 5%, 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.
Blade thickness with decreasing “spina di pesce” profile to improve fin directionality and achieve greater inertia at the end 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.

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.
