Fin Open Heel Cressi Thor EBS BLACK L – Powerful Water-Channeling

Brand new design for this extremely effective and yet very easy to use fin. The special arched profile of the fin, combined with the two central ribs promote a significant flow convection effect, known as spoon effect”, which stabilizes and boosts propulsion. Two lateral holes discharge the negative forces typically associated with this area and at the same time make for enhanced stability. The blades are molded from two different materials for improved reactivity.

These fins are perfect for scuba diving, whether you are an experienced diver or a novice. The Thor is made with the exclusive 3-material injection system patented by Cressi, which provides an excellent combination of strength, power, comfort, and aesthetics. This version of the Thor come with the standard foot strap with squeeze-style side release buckles. Under blade foot pocket design provides fast transmission of applied energy and great structural rigidity. Fins are available in multiple sizes and colors.

EBS SYSTEM, Cressi has developed this special strap to meet the needs of the most demanding divers, who need a comfortable fastening for their foot but one that is still practical and manageable.
Its special amply sized slot makes it very easy to put on, even when wearing thick gloves or three-fingered gloves for winter water.
The wrapping section is highly flexible, making adjustments unnecessary, and as a result it’s much easier to get all your equipment right in the first few meters of your descent and the fin stays in place against your foot despiten the increase in hydrostatic pressure.

It’s adaptable to all Cressi models, both with traditional hook  (Frog, Master Frog, Prolight) and rotating bayonet   (Thor, ARA, Reaction, Frog Plus).

Polypropylene blade: This material, inherited from apnea fins, has as its main characteristic the very fast transmission of applied energy and its great structural rigidity. It is applied to the shovel and inner area of ​​the sole sandwich. He is very nervous and reactive and facilitates a very agile and effective flutter. It has a stress-performance ratio clearly superior to traditional materials (natural rubber or thermoplastic, polyurethane, EVA). Likewise, it has a great resistance to breakage to the point that Cressi guarantees it for life for sporting use.

The inclination of the blade with respect to the foot pocket has increased by 5% compared to traditional diving models. This angulation provides greater efficiency and a more natural foot position during fluttering.

Polypropylene of the high module: Especially reactive, it is applied to the nervaturas of the blade and is responsible for providing rigidity and return to the blade. This material connects the critical point of transmission of energy (the instep) with the nerves in one piece, avoiding the usual loss of energy through excessively flexible components of the foot pocket that produce a heavy, slow and fatigue fluttering the instep .

The two lateral nozzles located in the zone where the flexion starts release the associated negative forces and allow the use of two ribs of high rigidity

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: Footrest toe, interior of the sole and area of ​​the instep in contact with the ankle. It is also assigned to the areas that require non-slip capacity: Inserts in the sole (area in contact with the ground) and anti-shock, such as the lateral nerves of the blade. The fusion of both materials is done at the molecular level and its strength is guaranteed for life for sports use.

Central area of ​​the thermoplastic rubber blade of convex section assembled in the polypropylene blade.

Foot pocket reinforced in the upper area by a supplementary thickness and laterally by two extensions of polypropylene from the upper to avoid the dispersion of energy in the process of transmission from the foot to the blade.
