Kevin M : I'm 6'-4" tall. I'm a big man with big wide feet. On top of that I have a high instep. I wear a US size 15 EEE shoe. The bottom of my feet measure (30cmX12cm).  Would the XL Fit me with or without socks?RONALD P : I can only guess that they are not big enough. I only have size 12 shoes, but my wet suit boots have large, hard soles. They are just barely large enough to get over my feet and boots.thomas M : I wear 13, with bootie, i believe you should have enough cup on the foot to still have decent leverage while kicking with 15s. I also think the strap should suficeCHESTER S : These are great fins, but you've just got to try a pair to make sure - ideally while actually diving.

Sized for use with BOOTS

All the reviews that say what a great fin these are, are right. However ! The foot pocket is definitely designed for used with a boot. I was upgrading from cheap adjustable fins that I wore barefoot, so I did not know that boots would be an expected part of the fit on these fins. Do not make the same mistake I made. Do get these if you have scuba boots. Do not expect them to fit barefoot. I will be going to the NYC storefront to try on full foot fins.

Hands down the BEST fins!!!

These fins are AMAZING!!! My first ever fins were similar mares & I loved them so much. I'm so glad I went back to this style/Mares when I got back into diving. will never regret it! Trusted, amazing brand w. incredible gear. RE chart my 7.5 shoe=S but in pool test lost a fin a few times (no bungee tension, heel @edge). XS works way better for me. And I love the Aqua color! Tried buckle straps on these but liked the ease of bungee way better. Love that you can switch/replace w Mares strap system tho. Super easy to don/remove in all situations. LOVE BUNGEE! Propulsion is stellar. Easy to maneuver w, great glide, conserve air/no over-exertion. I've tested a few other fins and personally, none compare. Def worth the investment!!!! Won't dive/travel w.o them. & <a href="http://Scuba.com" target="_blank">Scuba.com</a> is excellent! super fast shipping, well pkgd & beyond amazing CS; i always have Qs re shipping, sizing, prices, tech etc and they're always incredibly knowledgeable, helpful & accommodating. Def my go to for gear :)

My go-to fins for currents

My favorite fins! This is my 2nd time purchasing these fins. They are lightweight but powerful in moderate currents. Easy to get on and off as well.

Fins are great but straps are not durable

Fins are great, easy to maneuver in the water with ease. The bungee straps are crap and will break after a couple of years of saltwater diving. If I had to purchase again I wouldn't just because of the straps knowing it would need to be replaced

LOVE these fins! They are so easy to slip on and off, especially for beach diving. They are neutrally buoyant and don?t feel heavy underwater. They have a lot of kicking power and aren?t super hard to maneuver

Great Fins!

This was my first experience with the Mares Avanti Quattro-Plus fins and they were fantastic. They are very strong and durable, yet flexible and easily facilitate any finning technique under the water. As always, the customer service at Leisure Pro is top notch!

Mares Avanti Quattro-Plus Open Heel Fin

I have been a scuba diver for over 20 years, I have bought many name brand fins that were good but nothing like the Mares Avanti Quattro-Plus Open Heel Fin. Their light weight construction and durability literally propelled me through the water with little effort. I highly recommend these fins for all of your scuba needs, I have a friend and his have lasted ten years. Buy these fins you want regret it.

Recommended highly

I’ve used these fins for more than a decade. They are still going strong. These fins are perfect for maneuvering in all situations. With just a flick of an ankle, you can go where you need to go. Also powerful in the currents and surge.

Size 9.5 with 5mm boot fit perfect.

I bought the demo fin in Regular size. My size 9.5 men's foot with a 5mm size 9 Mares boot is a nice fit. FYI: These definitely need a boot and not just a 5mm sock. The fin arrived in close to new condition. Is definitely stiffer and longer than my ScubaPro Go large fins (needed large for socks or bare feet).

Good fit. Versatile

Fits good. Good for different kick styles which makes it versatile. Does need legs on the stronger side, but that comes with the heavy-gear-carrying-around workout that most if not all scuba divers go through.

Great fins for Cozumel

These fins are just great. With the bungee straps, they are easy to don and remove. They are great for finning and frog kick, and powerful enough to fin against a strong current in Cozumel if need be. We wear them with Cressi Carib 3mm Dive Slippers, very comfortable. Previously, we tried wearing only neoprene socks, but the bungee strap would make our feet go too deep in the pocket and our toes would be crushed in the front.

Great fin to swim in strong currrents

Tried them in a recent trip to Cozumel, sometimes currents are strong and these performed as I expected. A few kicks would give enough propulsion to effortlessly move through the water. Highly recommend them

The only fin you'll ever need

By Stan

I bought these fins right before an internship in Little Cayman, Cayman Islands. Let me first say the folks at LeisurePro were super helpful with the return and shipping me the proper size the day before my trip. I've done it all with these fins- from conducting coral surveys on reef crests barely a foot deep, to pinnacle diving on Grand Cayman at 105 feet and freediving to the bottom of the Kittiwake wreck. They are pretty powerful when you use them correctly, so it definitely takes some ...

LOVE these fins!

LOVE these fins! They are so easy to slip on and off, especially for beach diving. They are neutrally buoyant and don?t feel heavy underwater. They have a lot of kicking power and aren?t super hard to maneuver

Avanti Quattro + Open Heel Fin

Mares Quattro fans listen up! Mares' development engineers have subjected the world's best-known fin to a fine tuning. The result is the ‘Avanti Quattro +’. The legend lives on

Mares fins, such as the Quattro, Volo, and X-Stream models, stand for the highest requirements for open heel fins in diving. They are the result of continuous development and research at Mares HQ. Nevertheless, the fin development team asked themselves how could the ‘Quattro’ – a legend among fins – be improved even further? Incredible, but true – the result is the Avanti Quattro +.

CENTER OF POWER. EDGE OF PERFORMANCE

The most sold diving fin in the world now redefines itself. Greater responsiveness paired with traditional thrusting power optimizes ultimate performance. This fin can handle any and all diving conditions while leaving the others behind. Featured with Mares' new bungee strap, donning and doffing is simple and efficient.

Avanti Quattro +

Countless computer simulations and field tests were performed, until the Quattro + was perfected. The result is noticed immediately: The fin can be operated "more smoothly" and the enhanced energy transmission (foot-foot pocket interface) is not only noticeable, but measurable.

The legend's design has been adjusted as well, with the Quattro + available in a range of vibrant colors to customize your dive style.

Avanti Quattro +

When developing Channel Thrust technology, Mares dedicated itself to new forms which would allow for remarkably improved performance, meaning greater thrust with less effort. Focus was given to how water channelling could be improved and, at the same time, how the so-called ‘dead angles’ of a fin stroke could be minimised.

Avanti Quattro +

During the fin’s movement, only some of the displaced water is sent in the direction of movement. Unfortunately, some of it flows over the sides of the blade and does not contribute to thrust, only causing a decrease in efficiency. With the revolutionary design of Mares’ Avanti fins, the channelling of fluids is maximised and, contemporarily, a quantity of water is moved which is notably greater compared to other fins of similar dimensions.

Channel Thrust technology: Maximum thrust with minimum effort!

Avanti Quattro +

The Avanti Quattro + non-vented fin exceeds the established performance of the traditional model thanks to the use of composite materials Tecralene, Thermoplastic Rubber that optimize efficiency. The Avanti Quattro + provide greater responsiveness and thrusting power with an even more attractive look. New bungee straps are provided as standard issue. Straps are equipped with large grasp-loops for easy donning and doffing. Proven Channel Thrust Technology makes the fin versatile and ideal in all diving conditions.

The stabilizers improve stability and eliminating ankle twisting phenomena. The anatomical foot pocket conveys more power to the blade. Mares design is 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. Fin is available in multiple sizes and colors. The regular size fin blade measures 15" (38cm), weighs 32 oz. (907 g) and has a blade surface area of 120.9 cubic inches (780 cubic centimeters).
