X-STREAM.

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.

Features:

- 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.

Within a short period of time, this fin has broken every record and won every award. We are talking about the open heel fin X-Stream. So it´s about time we honor the top seller among the fins with some additional colors and an additional size.

Four patents set new standards! An intriguing look! An incredible sporty design and an entirely different foot pocket immediately lead to goosebumps. And once you pick the fin up the surprise is complete. Because the X-Stream´s super low weight will blow your mind. That´s about the effect at first contact. And when you´ll dive with it you´ll be completely convinced.

The X-Stream has also convinced the committee at the ´´red dot design award´´ and hundreds of thousands of satisfied divers around the world. ´´You forget that you are wearing a fin,´´ is the most common answer to the question why this fin is so popular. Here, comfortable fit and outstanding performance criteria go hand in hand: the newly designed foot pocket with its striking perforations (they eliminate the so-called parachute effect) and the hinges at the connection to the blade for absorbing kinetic energy do an excellent job in the service of the user. The blade with its extremely wide center rib makes for a powerful channeling effect based on the superchannel principle.

The lightness of being: all of these advantages make the X-Stream also the ideal fin for children and adolescents. So, it is only logical to broaden the spectrum of sizes by size XS. Head-turner: The X-Stream now comes in the 2013 fashion colors pink and white, so that it matches the new mask (X-VU) and snorkel (Ergo Dry) colors perfectly. But if you would prefer the X-Stream in solid black – be our guest! We will fulfill this wish in 2013 as well.

Specifications:

- Type: Open fin, “Split Fin”.
- Operating principle: Strong channeling effect through extra wide “super channel”, latest OPB generation for optimal angle of attack of the blade at every phase of the finning stroke.
- Material: Different thermoplastic rubbers (SEBS), polypropylene (PP).
- Blade (size R): Length: 37 cm, thrust area: 750 cm2.
- Buckles: ABS Plus System (patented).

I already had these fins in white that had broken at the bend. They were good in thrust/power ratio. Only regret: not always easy to put on. In orange they are nice.

High wearing comfort. A perfect fit with "normal" footlets. In the case of footlets with thick soles, take a size larger or else it will be tight. Very good propulsion. Light ... just a good product.

claudia-

Good afternoon. I wear a size 39/40. Would the 41-43 from Pink be too big? I really want my size, but only 34-37 or 41-43 are available, and I want to know if the 41-43 might be too big. Thank you.

Answer of Lidia

I bought the same ones in size XS before summer. I wear a size 36 with 5mm heels, and they´re a bit snug across the instep, but the length is quite tight, and I have to fasten the straps quite a bit for them to fit properly. My recommendation is: NO to sizes 34-37; they would be too small. Sizes 41-43 might work with 5mm heels, but I think you´d have to tighten the straps as much as they´ll go. In my humble opinion, I would buy the intermediate size between the two. Or, the easy solution, though not a very pleasant one, would be to get a different color. I hope this helps.

Is this quality good?

2025/07/29

Joan

Is the quality sufficient?

Answer of Neil

Usual mates quality. Perhaps a little light if you're using a 5mm wetsuit. Definitely not for use with a drysuit. Other than good solid fin with ample thrust.

Answer of Günther

Have 80 dives with the fins like my wife I with rubber pull my wife with adjustable clip closure with the quality we are very satisfied so far Mfg

Size 45-48

2025/03/26

Sergio Giuseppe

Size 45-48 is suitable for a foot size 42 EU, Mares N.9 shoes? Thanks

Answer of Miguel

I think it´ll be too big for you. A Mares Regular size for a 42 EU would be the size, and this fin is a 43-45. In this size range, 38-43 corresponds to an S; 43-45 R; 45-48 corresponds to a L.

size 38-43

2025/03/25

Sergio

With shoe size 9, foot size 42.5, is size 38-43 correct or too small?

Answer of Miguel

3s too small. Size 38-43 is an S in Mares. I wear a 41 EU (7.5 UK), so in Mares I wear an R (regular), and size 38-43 was too small for me.

Answer of Marko

Correct

correspondence with size R

2025/02/26

Miguel

Hello, I am interested in the Mares X-Stream Diving Fins, Yellow EU 38-43, Ref: (8077735). I would like to know if this size corresponds to the R in Mares, I have other Mares fins with bungee strap, and the size is R, and I had not seen this size of 38-43. Thank you.

Answer of Sandra

Yes the 38-43 would resemble the regular fit, I purchased the larger size to use with dry boots

Answer of Michael

I have size 45 in the equipment shoes and wear the R (43-45)

Size Equivalence and Bungee Strap

2023/09/26

Jacinto Castillo Naranjo

Hello, I am trying to buy two fins: Mares X-Stream Diving Fins. Yellow EU 38-43, Ref: (8077735) and another Mares X-Stream Diving Fins, Blue EU 34-37, Ref: (8077729) to replace the old ones, which were size: R and S respectively. Are these (now carved in EU type) the same ones? I also want to check/make sure that the buckles (the flap closure) are bungee type elastic. I started the same text yesterday afternoon to place the Order and they have not yet responded to me. Please respond quickly to place the Order, I am going on a trip and it is Urgent. Thank you

Answer of Carlos

Regarding the sizes, I can tell you that I bought my second fins with the numbering reference and I have had no problems. I haven´t noticed the slightest difference compared to the first ones. The straps are elastic, the same as the previous ones. I use elastic strips of the steel ones too. The latter have the disadvantage that the steel anchor leaves small scratches on the plastic of the fin due to the different hardness of the materials. For size EU34-37 you would have to choose another color (blue/pink/white): https://www.tradeinn.com/diveinn/es/mares-aletas-buceo-x-stream/137048488/p

Answer of David

Depends on size but basically 2.9 lbs

Difference between x stream and x stream bn?

2020/08/10

Fran

What is the difference between the Mares X Stream fins and the X Stream BN model? Do the white silicone areas such as the bootie area yellow over time? Thanks in advance

Hello! BN means bungee (it comes with a bungee for packaging). Silicones are very high quality. White remains over time. Thanks for your question!

Best fins ever !!!!
