Features of Mares X-Stream

Product description of Mares X-Stream Diving Fins

Description summary

MARES X-Stream Diving Fins deliver unmatched efficiency and comfort for adult divers. Their innovative riddled foot pocket eliminates drag, while the Optimized Pivoting Blade (OPB) ensures maximum thrust with every kick. Lightweight technopolymer construction reduces fatigue, perfect for extended dives and travel. An adjustable strap guarantees a custom fit for all boot sizes. Experience a leap in fin technology with these powerful, fluid, and comfortable fins

MARES X-Stream Diving Fins: Experience Unrivaled Efficiency and Comfort

Revolutionize your underwater experience with the MARES X-Stream Diving Fins, the pinnacle of design and performance for the modern adult diver. Engineered for those who demand exceptional efficiency without sacrificing comfort, these fins translate every ounce of your energy into powerful, fluid propulsion. Move through the water with less effort, reduce your air consumption, and enjoy longer, more comfortable dives. The X-Stream´s innovative open-heel design, complete with an adjustable rubber strap, ensures a secure and customized fit for a wide range of boot sizes, making them the perfect companion for all your diving adventures.

The X-stream fins´ performance, comfort and lightweight design are the incredible result of sixty passionate years at the service of diving. The X-stream fins are truly a leap into the future, and change 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. This dedication to innovation is evident in every kick. The use of advanced plastic and technopolymer materials creates a fin that is not only powerful but also remarkably lightweight, reducing leg strain and making them ideal for both travel and extended use.

Discover the technology that sets the X-Stream apart. The intelligently designed riddled foot pocket is a game-changer, featuring perforations that drastically reduce the "parachute effect"—the water resistance and drag that builds up in traditional foot pockets. This allows water to drain freely, resulting in a smoother, more efficient kicking cycle with significantly less fatigue. Combined with the next-generation Optimized Pivoting Blade (OPB), the fin maintains an optimal angle throughout your kick, maximizing the useful surface area and generating consistent thrust. Furthermore, the unique blade construction is engineered to channel water flow and minimize turbulence, ensuring that all your power is directed straight behind you for maximum forward motion.

Features:

* X-stream Comfort, X-ceptional Efficiency: A perfect synergy of ergonomic design and hydrodynamic power for a superior diving experience.
* Riddled Foot Pocket: Eliminates the parachute effect by allowing water to pass through, reducing drag and leg fatigue.
* Next Generation OPB: The Optimized Pivoting Blade system ensures maximum thrust and efficiency through every phase of the kicking motion.
* Blade Construction for Less Turbulence: A central channel stabilizes the fin and directs water flow, creating powerful, stable, and efficient propulsion.

Technical Specifications:

* Blade Length: 37cm
* Material: Thermoplastic Rubber/Technopolymers
* Type: Adjustable rubber, Adult, Diving, Plastic

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.

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.

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.

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
