Mares Avanti Quattro-Plus Open Heel Fins, Royal Yellow

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 four ribs design allows the fins to arch during the fin stroke. The water is then channelled in the opposite direction of motion, minimising pressure loss at the side edges of the fin. Muscle power is thus transformed into propulsive thrust.

• 4-channel design for more propulsion
• Highly flexible material that optimises blade efficiency
• Channel Thrust technology
• Thermoplastic rubber foot pocket and "Tecralene" technopolymer blade
• Stabilising fins"
