Features Explained

• 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
