The special arched profile of the fins combined with the two central ribs promote a significant flow convection effect, known as “spoon effect”, which stabilises 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 moulded from two different materials for improved reactivity. These fins are perfect for scuba diving, whether you are an experienced diver or a novice.
The new Cressi 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 channelling and acceleration of water flow, which stabilizes and increases propulsion at equal effort.
The special strap meets 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.
