Mares Avanti Quattro 4X: complete review and opinion (2026)

Our evaluation method

To analyse the efficiency of this premium reference in a standardised way, we assess five criteria of equal weight. No individual field test was carried out by us on this pair. The overall score of 4.55 out of 5 reflects its theoretical design quality, without guaranteeing individual comfort.

The Mares Avanti Quattro 4X is a high end adjustable fin designed for scuba diving, cold water immersion and underwater photography. Its open heel comfortably accepts thick boots.

The responsiveness of its blade makes it remarkably effective against sustained coastal currents. At an average weight of 950 g per fin, it delivers stability and a solid footing underwater.

The blade uses the patented Techralene 4X compound with four flexible channels that funnel water during the thrust phase of the kick. This architecture produces an excellent flutter kick with very good efficiency.

Picture a photographer with a carbon tripod fitted with wide rubber suction pads. However unstable the ground, those pads hold everything steady enough to capture sharp images without slipping. That is the advantage of the non-slip sole on this premium adjustable blade when it comes to holding position. Frog kick and back kick remain exceptional underwater.

The ergonomic foot pocket in soft thermoplastic rubber follows the contours of the boot closely, eliminating painful rubbing. The bungee straps make the fins easy to put on.

Muscle fatigue and pressure on the foot are kept to a minimum, earning the highest comfort score in our comparator. This is an ideal model for extended exploration dives in cold water.

The structure combines high quality polypropylene with elastomers of varying densities to optimise flex. The fin is neutrally buoyant underwater, which preserves horizontal trim.

These high end composite components withstand sun and salt exposure very well. The shape memory of the 4X channels prevents any loss of thrust over the years.

Thick side rails effectively protect the blade from cuts and abrasion on coral reefs. The bungee strap anchor points are remarkably solid.

The reinforced non-slip sole offers excellent safety when walking on wet rocks. The overall longevity of this premium model makes it one of the most durable investments on the market.
