The Thor EBS features a new innovative design developed with all the Cressi experience, offering a scuba diving fin easy to maneuver and to use in any condition. The special arched profile of the fin, combined with the two central ribs promotes 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. Made with the exclusive 3-material injection system patented by Cressi, which provides an excellent combination of strength, power, comfort, and aesthetics. Fins come equipped with Cress'si Elastic Bungee System (EBS) which makes use of a round bungee cord band that accommodates all foot sizes for a perfect fit. 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 thermoplastic rubber with a convex section, assembled in a polypropylene blade. Two lateral nozzles, located in the area where the flexion starts, release the associated negative forces and allow the use of two high-response ribs. This combination causes a channeling and acceleration of water flow, which stabilizes and increases propulsion at equal effort. 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. Thor enjoys the exclusive 3-material injection system patented by Cressi, which provides an excellent combination of strength, power, comfort and aesthetics and the optimization of the requirements of each area of the fin.
