About Mares X-Stream Open Heel Fins

The X-Stream Fin from Mares is a performance, comfortable and lightweight design and 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. The limiting factors in traditional open heel foot pockets are their weight and the parachute effect". When finning, water gets into the space between the bootie and the foot pocket, creating drag like the air in a parachute. The perforations prevent this and have the additional benefit of making the foot pocket very soft and flexible. Furthermore, the suction effect which can make doffing of the fins cumbersome, is now forever a thing of the past. X-Stream 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. Mares design inspired by marine mammals. Channel thrust technology maximizes the channeling of water and moves a much greater amount of water compared to other fins of the same size. The result is greater thrusting power with the same amount of effort. The adjustable fin straps are equipped with large heel pull tabs for easy donning and doffing. Fins overall lengths are 23" to 25.2" (60 cm to 64 cm) depending on size and weights 2.9 lbs. (1.34 kg). Fins are available in multiple sizes and colors.

Amazing fins

I've been using these professionally for 3 years, teaching and leading dives in Lake Mead, San Diego and Isla Mujeres Mexico for the last 18 months. Light ( float ), kick soft, then power up when you kick hard. flick light for positioning when taking pictures. They track very well which takes pressure off the knees. ( I tried another company's hi-tech fins, had to use knee strength to get them to hold a straight line ). Hundreds of dives on them at this point, no problems with the buckle...

Breaks easily

Bought these fins, after i unboxed them i tried them on and one of the straps that came with the fins broke. I ordered the bungie straps that mares sells and thought problem solved. I used my hollis fins and allowed my friend to use these, after we finished diving i asked him if he like them and he said they lacked power. In disbelief because the reviews spoke so highly of the product, i headed out through the surf to try them myself. While donning the fins in the surf a wave pushed the blade...

My dive buddies.


from Lima, Lima, PE

The most confortable fin I've ever used. I have frog kicked the hella out of this beauty and still rockin! Really light = Perfect for traveling I bought this bad boys 3 years ago and still rockin, the only issue is the strap, they are waaaay confortable with the bungie straps. 10/10 would buy again.




from Lakewood, CO, US

I absolutely love these fin's. The first pair I bought I wish I would have bought the larger size, but all I had to do was go from my full booties to half ones and then they fit perfectly. Great power, easy on and off and I would also recommend buying the bungy straps for them and get rid of the existing ones. I've since bought another pair and could not be happier with these fins. Highly recommend them, great for traveling, small, compact and easy to pack


Love these fins!


from Mentor , OH, US

I'm very happy with these fins, very light weight and great propulsion also! I've had them on multiple dive trips and are holding up with no problems.


Just what I was looking for


I have been using Sherwood Trek split fins for several years and absolutely love them...while diving. However they presented me with two problems. First, they are so big they are difficult to fit in the fin pocket of my travel bag. Next and more troubling is that they suction to my boots and are extremely difficult to remove when preparing to get back on the boat. So I tried these X-Stream fins and love them. These are so easy to remove and they fit my gear bag nicely. Although skeptical at first, I like the buckles on the straps. I had to modify my kick slightly, but that was easy and actually fun to learn something new. These provide lots of thrust and are effective against strong current. Overall a very comfortable and efficient fin, highly recommended.


Good power and speed when needed


from Rochester, NY, US

Bought these for diving the St Lawrence where there can be strong currents; fins performed well providing power and speed when needed. Recommend these fins.

LUDWING G  livianas , buen desempeño , buenas para un niño o mujer por livianas .
WILLIAM G  Online and first person reviews led me to these fins. They do not disappoint
Michael O  My wife had a pair and got tired of me stealing hers.
James R  nice fins great price
Alessandro M  Excelent, the best fin ever!!!!!
LINDA H  Excellent fin!! Powerful but very light weight. I've been extremely happy with this fin.
ROBERT M P  I bought these fins for diving in strong currents.
EMERICH H  I choose this fins because mares are great for easy displacing below the water. Colours also are very great and different from the traditional black fins
Lena T  could you please tell, description says that weight is 2.9 lb . Is it weight of one fin or two fins?
Frank L  Combined weight of both fins.
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.
ANDREW K  My yellow and clear (white) still look great after 150 dives
