The Avanti 4X is the long-awaited evolution of the legendary Avanti Quattro+. Designed for divers of all levels, this open-heel fin combines comfort, power, and precise control. Whether you prefer flutter, frog, or back kicks, the Avanti 4X delivers smooth, efficient propulsion with minimal effort.
Its construction merges Mares’ proven technologies with innovative refinements to improve performance in every underwater scenario.

Key features:
• Dual-material construction for performance and comfort:
The entire fin is made from two 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, L, XL
