About Mares X-Stream Open Heel Fins

X-stream comfort, X-ceptional efficiency
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.

The Optimized Pivoting Blade system (OPB) 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.

The ergonomically designed foot pocket delivers maximum power and evenly distributes pressure over the foot to minimize fatigue. The foot pocket interior features internal ribbing that improves fit, eliminates foot suction and prevents foot pocket flexing, while transmitting more power to the blade.

X-Streme uses Mares patented design ABS Plus Buckles (Adjustable Binding System). It only takes one quick movement to easily open or close these buckles, even when wearing thick neoprene gloves. The double button release prevents the buckles from accidentally opening making them the most user friendly system on the market.

The Super-Channel is designed for the diver who wants the perfect blend of power and efficiency in one fin. The new blade design with a large central Super-channel and two traditional lateral channels provide excellent thrust while maintaining hi-efficiency and minimizing leg fatigue. The blade uses Tri-Material Construction, constructed of Techno-Polymers and Thermoplastic rubber for extended durability.

Fin comes in four colors and three sizes, has an overall length between 23" to 25.2" (60 to 64 cm) depending on size and weights 2.9 lbs (1.34 kg); fins come with a 24 month limited warranty.

Questions about this item:

Shopper  Why Did You Choose This?
WILLIAM G  Online and first person reviews led me to these fins. They do not disappoint
caitlyn c  Anyone bought the pink/white mares x stream fins? Didn't know if the white part became dirty after multiple uses, or if they were "cheap" looking in person.
JAMES M  I do not have the pink/white, but I do have the blue/white and they get a little dirty, but my main issue is with performance. The Mares Volo Power is so much better on the surface and in the water I don't know why anyone would buy these fins. The Bolo Power are also less prone to breaking because there is no weak hinge point like on the X-Stream. Just my 2 cents.
eldon O  What is the speed in mph.?
Frank L  Fins are not measured in MPH. These are efficient fins, easy on your knees.
