The Avanti Quattro + diving fins have a blade length that varies from 37 to 39 cm depending on the size. The fins have an open foot pocket. The design with the four ribs allows the fins to arch during the kick. The water is then channeled in the opposite direction of the motion, minimizing the loss on the lateral edges of the fin. Muscle force is thus transformed into propulsive thrust.
A new composition of the material used in the Avanti Quattro+ allows the fins to absorb energy even more easily, which is then transmitted in a better and more optimised way.

The special channel thrust system creates a geometry of channels capable of moving a greater quantity of water, creating a superior thrust with the same effort. The result is a fin with very high performance dedicated to the most demanding divers.

The newly designed shoe features prominent perforations (which prevent the so-called “parachute effect”) and the joints at the junction with the blade absorb kinetic energy. The blade, with its extremely wide central lamella, ensures a strong channeling effect according to the Superchannel principle.

The main features of the Avanti Quattro + diving fins are:

• 4-channel design for greater propulsion
• Highly flexible material that optimizes the efficiency of the blade
• Channel Thrust Technology
• Thermoplastic rubber boot and “Tecralene” technopolymer blade
• Stabilizer fins
