Mares Avanti Quattro 4X Open Heel Diving Fins

The Mares Avanti QUATTRO 4X is the next-generation open-heel fin, combining comfort, power, and control. With a three-material blade, optimized foot pocket, and 4-channel thrust system, it delivers efficient propulsion and all-day comfort. Features include stabilizing ribs, bungee strap, anatomical heel pad, and a reusable mesh bag. Key features: Three-material construction for performance and comfort: The entire fin is made from three different materials. This combination allows for a flexible yet responsive blade that maximizes thrust while reducing fatigue. The blend of materials is carefully chosen to balance power, durability, and diving comfort. Optimized foot pocket design: The upper section of the foot pocket is made from soft thermoplastic rubber for a snug and comfortable fit. The lower section is reinforced and extends into the blade, improving stability and ensuring that leg energy is transferred efficiently into forward motion. 4-channel blade for greater propulsion: Four channels along the blade bend and guide water efficiently, increasing thrust and reducing leg fatigue, even on longer dives. Stabilizing side ribs with overmolding: The side ribs improve blade flex and reduce lateral movement. Overmolding reinforces the ribs and increases the channeling effect while adding a sleek visual finish. Anatomical heel pad: Reduces stress on tendons and increases comfort. The large loop allows for quick donning and doffing, even with gloves. Elastic bungee strap with protective cover: Easy to use, adaptable to different foot shapes, and protected to increase durability. Anti-slip sole: A rubberized grip under the foot pocket ensures a firm hold on wet surfaces, making the fin safer to wear on boats or rocky shores. Reusable mesh bag: Supplied with a quick-drying carry bag that supports Mares' commitment to reducing single-use plastic. Available sizes: XS, S, R, XL
