The Mares Plana Avanti Quattro Plus Open Heel diving fins are designed for scuba and diving gear use, delivering efficient propulsion and reliable performance in challenging underwater conditions. Blade length ranges from 37 to 39 cm depending on size, and the four-rib blade allows arching during the fin stroke to channel water in the opposite direction of motion, reducing resistance.

Built with a thermoplastic rubber foot pocket and a Tecralene® technopolymer blade, these fins are designed for durability and flexible response. The Channel Thrust technology, along with large perforations in the foot pocket, helps optimize water flow and minimize the parachute effect for smoother, more controlled kicks. Available in sizes S–XL to fit a wide range of divers.
