Mares X-Stream Fins

The X-stream performance, comfort and lightweight design are the incredible result of sixty passionate years at the service of diving, The X-stream is truly a leap into the future, and changes forever how we envision the creation of a fin. More than 2 years of resources, experiments and testing and four Mares patents all concentrated in one unique product.

Riddled Foot Pocket:

The perforations prevent stagnating water flow from slowing you down. Eliminating this “parachute effect” you’ll slide faster through the water. Furthermore the openings eliminate any suction effect, making doffing easier.

OPB - Optimized Pivoting Blade:

Allows the blade to maintain an optimal angle throughout the kicking cycle, whereas traditional fins achieve this only during a small portion of the cycle. OPB produces a constant thrust, which minimizes fatigue and produces fluid movement through the water.

Channel Thrust:

Soft longitudinal inserts allow a controlled deformation of the fin blade while kicking. This channel shape moves a greater amount of water resulting in more thrust for the same effort.

Tri-Material Construction:

3 specific materials for maximum elasticity, high durability and resistance to aging. The result is superior performance in all diving conditions.

The Mares X-Stream Fins 


  • New foot pocket. No parachute effect
  • Next generation OPB
  • New blade construction for less turbulence

*Please note: Pink is not available in size X-Large
