Great fins!

I have flat feet and need to be very conscientious of my choice in fins due to foot cramping. I took these fins to Bonaire because I needed to wear thick soled dive booties and they did not disappoint. My dive buddy often had to tell me to slow down, as these propelled me faster than my usual split fins. They also did not cause foot or leg cramps. Though I could feel my multiple days of diving in my calves, I don't attribute this to these fins as 4 dives a day, often needing to swim a mile or so out to a buoy was likely the real cause. They are rigid but not impossible to bend, are lighter weight, and fit nicely into a small suitcase. They are a great price for a fantastic pair of fins. Very happy with this purchase.

Has no locks on straps

Came off while diving as the release hit kelp while abalone diving . Nearly lost fin. Not recommended for California diving. Get the fins with locks.

Mares Avanti X3 open heel fins

These fins are perfect for scuba with boots. They can also be used for snorkeling. The sizing is just about right on. They are comfortable and pretty efficient. They bend just enough to not give leg or foot cramps.

Size chart is not correct

Do not order items as a gift as the return clock starts ticking the minute your order is sent!! Ordered these fins end of Oct for my wife for Christmas. Finally started dive lessons in March. She tried them on and they dwarfed her foot! Contacted LP to return the brand new fins for an exchange-They said NO even though they still sell the fins-Store Policy-Seems like a great way to convince me to order again--My policy--Don't order product from people who don't put the customer first.

Made to last, comfortable to use.

As promised, something that has performed well beyond expectations. Initially I trusted the dive shop employee who sold my first and only set of fins. They were bought in at a shop in Jacksonville. The cost was about $125, although a quick search on LeisurePro list them for way less. They were purchased right before doing the PADI Rescue course. Approximately 12 years later and over 5000 dives they are still going strong. Now that's value, and no warranty required. There is a Mares dealer here in West-End who sells these and newer versions of the fins but the only thing that has been replaced is the straps. When the weather gets nasty on the north side we dive the south. At times we do shore dive in Flowers Bay over by Church Wall. That's when the open heel fins earn their money. To clarify, we carry a large variety of closed heel fins, some of which are never picked because they are simply to hard to put on and much less take off while hanging to the back of the ladder. I've tried the split fins and they definitely have less resistance and thus less stress on your knees. I'd hate to have to tow someone back to the boat against a current using split fins however. I'm just making the case that the Mares Open Heel fins are good and reliable. On a separate note, we have used a variety of close heel fins for just about all our rentals when boat diving. During that time, it is also the Mares closed heel fins which have lasted the test of time. They get the double oks from this reviewer. That's not to say I'm not going to try a different pair. Until next time, happy bubbles.

LOVE THESE FINS!!!

I love these fins, even though I ordered them at least a half-size too big, (so I wear socks in my booties and they fit fine). My fault. My Dive Master/Instructor had a set of these and of all the fins I tried, I liked these the best, so I bought a set. They are the perfect balance and combination of performance and comfort. The fact that they look fantastic is just icing on the cake. (I have the yellow color). I ordered these with several other items and all were delivered EARLY, and packaged very well. Always a fantastic buying experience, and great people, thank you Leisure Pro!

Very Impressed

Since this is my first fin purchase, I may be writing a little too soon, however my first time in the water with these fins was phenominal. I have tried different fins in the pool during my open water class and wasn't too impressed. Two that come to mind are the Aqualung Slingshots and the Scubapro Seawing Nova. During my second OW dive, the instructor wanted to see if I could keep up, and with my poor kicking style I was able to and he had the Novas on. After two dives I had no leg cramps at all from the fins. The only thing I would recommend that Mares do is add the spring straps as they can be quite cumbersome to put on in the water when entering from shore. Maybe it was just me as I said I am new to scuba. Overall, very satisfied with these fins.

workhorse fins

These fins are intended for those who have strong legs, they're quite rigid but very efficient, you just need a time to get used to them. Besides, you can cut the blades from the middle and make split fins(all egyptian divers do so). I was using them in Egypt and had no problems with strong currents. They also can be used in diving centers as a rental equipment. Moreover,if you make shore dives these fins will be the best choice 'cause they're durable and won't wear out.

Mares X3 fins

Good basic fin. I wear a size 13 shoe am 6'1"185lbs and had to exchange the xl for a regular, but no hassle LP's exchange policy is easy. These were still to big for bare foot use but fit just about right with 3mm boots, maybe a tad big with boots but better that than too small. I like the heel straps and quick release buckles. they are a relatively stiff fin but I have strong legs and ankles from cycling so that wasnt an issue for me and you can really make good speed with them when needed or fighting a current. They fit my gear bag for travel to which was a primary concern

Great fins!

I've always used split fins when diving and since we always drift dive, I thought the Mares fins would work better when swimming into the current. They worked very well and I will continue to use these when drift diving. I did have a bit of a challenge at first getting the fins off in the water while hanging onto the rope on the side of the boat. These fins have buckles on both sides of the straps and the strap doesn't detach from the fin. My other fins unbuckle and the strap detaches on one side, so that's what I was used to. However, after a couple of dives, I had no problem getting the fins off and throwing them into the boat.

Works well, good in low visibility

Bought these initially for the open water class and now have used them on about 10 dives. They seem to work well. The blue is a nice bright color that makes them easy to find if one comes off while diving (which happened on my checkout dive)

Performs well

Bought these for my daughter for our open water training and they worked well. Nice bright colors which makes it easy to find if the fin comes off while diving, which happened to me (I have a blue pair) during our checkout dive in a quarry. The dive master who found the fin said she only found it because of the color!

Get what you pay for!!

As a former Navy Specwar Diver my standards are high indeed. This fin is a starter for folks on a budget. And it will do the job required of it. However this fin will cause much more leg fatigue than higher dollar fins. Also left in the sun (90f) for 2 hours one fin is now warped. I will return this and get a better made fin.

Best I've used

I've owned a number of fins, including similar full blade, split and hingled but this is the fin I like best. Decided to try it after watching videos of sidemount divers using the same brand, next grade up. Sidemount divers tend to be cave divers and need power and efficiency. I really like the power of the fin, I trim well with it, and it is an excellent fit to my Henderson 5 mil boots. I have a 8.5 shoe size (male) and got the recommended size, small. The buckle system works fine in the water but was initially difficult when dry. Read the directions, its not obvious how to use them. The fins are also short enough to travel in my blue reef bag.

nice fins, way too big

these are nice fins, but the sizing is way off. I have large feet, typically around 9 1/2 men's but up to 11 depending on manufacturer and originally ordered a "regular" which was way too big and felt "wobbly". re-ordered a "small" which fits fine even with 6mm booties (booties are size 9 men's). Mares seems to have changed the design of the buckle - my first set had a design where you lift the buckle with a tab on the front and I found that rather difficult to handle. the second smaller set has 2 small buttons on the top and bottom of the buckle which you press to release, which I like better.

I use this product as an instructor it gives excellent power so little effort is needed and it functions very well for light work,but can get you out of trouble if you need the power for a strong current!!!

Not so good

These fins are just plain bulky. I'm a big guy and it takes some *umph* to get these fins going. They have little to no flex, are too big for my dive bag, and have not loosened up even after 2 yrs of diving with them.

The Mares Avanti X3 is the perfect combination of comfort and power for recreational divers and snorkelers. The mid-sized blade has three channels for optimal movement. The fin blade is made of Tecraclene: blade with three channels for optimizing water flow, the center channel is inverted to make better use of the glide stroke. The upper and lower stabilizers help maximize muscle energy conversion.

Tecraclene ribs in the foot pocket afford an improved fit and permit more efficient transmission of the kicking action. The range of sizes is complete to better accommodate all requirements, including those of women and younger divers. The straps feature the ABS Plus (Adjustable Binding System) for single-handed adjustment. The Mares Avanti X3 is a successful marriage of comfort and power. The Avanti X3 uses Mares patented design ABS Plus Buckles. 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 accidently opening making them the most user-friendly system on the market. Fin comes in multiple colors and sizes, has an overall length between 22.2" to 26.4" (56.5cm to 67cm) depending on size. Fins are made from Tecralene, and weigh between 2.8 lbs. to 4.6 lbs. (1.28 kg to 2.08 kg). Available in multiple sizes and colors.
