Top Notch!

Without question, the best fins I've owned in 16 years of diving. I recently switched to these fins while diving in Thailand. Due to strong current at some of the dive sites (Similans / Koh Bon / Richelieu Rock) I was struggling to kick through and spent a lot of time and air to do so with my Atomic fins. Between liveaboard trips I picked these up and they were an absolute dream. Effort reduced by 60-80%, resulting in longer and more relaxed dives when faced with moderate to strong curren...

Sturdy Fins but Heavy for Smaller Women

Sturdy, powerful fins, but heavy to pack and also during use. Vigorous finning, even with proper technique, causes cramps. They weigh 5lbs for a small pair.

Great, Sturdy Fin


This fun put me through my open water certification class. I decided on a stiffer fin because I will be moving on to rescue diver within a few months. This is a very stiff fin. However, some of us favor a stiffer fin. As my second pair of fins, the Mares Avanti Quattro has become my "go-to" for any diving environment. The bungee heel strap had me a bit worried to begin with. That fear is gone. Mares did a great job at designing a sturdy product. The fin feels true to size. I purchased SM and wear a size 8 shoe. My booties are 5mm. The foot pocket also feels true to size. Overall: great product. If you purchase, be prepared to work yourself into these fins. However, it's totally worth it.


Good performing fin, large pocket.


I was concerned on buying the largest of the fins (XL) - I am a size 12 with a bootee. The L would have been a more snug fit although in use, I have enjoyed these greatly, with the larger pocket. The fin is exceptionally well made although I do have some concern about the bungee cord feature, being used to stainless steel strap of my aged Beauchat Jetfins, this is somewhat new and I hope will give me good service. Just used them for a week and never had any cramps...but then I am a photographer and swim slowly... I wanted them to be lighter than the 25 year old all rubber Jetfins I have used. They are somewhat lighter but quite a bit longer... Overall I am happy with the purchase...I may have gone with the L if I'd had the chance to do a side by side comparison...but these will be my diving fins for the future...breaking bungee cord notwithstanding....


Best fin on the market!


Divemaster with 45 years in the water. Have used this fin for some 15 years and it always performs flawlessly. I suggest you zip tie the buckle system closed and just pull the strap over your booty to put them on. Trim off the excessive fin strap and you are now streamlined.


best fins i ever used


im using the same fins since 2008 or 2009... they never faild me, best so far (used others during this time when i travel) i think my next fins will be just same as thoes ones mine are same as thoes just new pair


Great buy!


With the snap open buckles, it makes getting in and out of boats quick and easy without having to readjusting how tight it fits. One thing extra that I love is that mares packages a replaceable strap/buckle combo to keep in your save a dive kit for quick swap.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
RANDY B  Bought a pair back in 1997 and simply love them. I know that split fins are the in thing but I love how fast the Quattro propels me in heavy current. Never a problem with these fins. My son is now getting certified and he needs a pair of fins. Guess what ones I want him to have? That is why we bought them.
HEIDI M  I used them since I start scuabe diving 10 year´s ago. This are my second pair.
CHRISTIAN A  fastest fin on the market.
Jan N  Best fins ever made for every type of diving except technical cave and wreck. Too soft to swim backwards with.
Shopper  Do the foot pockets accept size 12 Hard Sole boots?
MAURICE D  Easily, I wear a 14 and have no trouble.
JEFFREY L  They do accept my size 12 lightweight hard sole boots. Sole sizes and thicknesses may vary but there is plenty of room with mine. A great fin.
Dennis T  I'd probably say no, I wear a size 10 shoe and they are perfect
MITCHELL T  I'm sorry I cannot give you a definitive answer, but I dive xlg with 11 hard soles. Very comfortable, feels like room for more. I've also swapped the stock straps for springs. These are excellent fins, especially for the coin. Much better than split fins in a current.
LEONARD G  I have the XL Open heel Quattro fins. I wear size twelve 4th element hard sole booties. No problem with comfort.
jeff p  is there a big diffence between this fin and the advanti quattro plus?
Frank L  They are almost identical. Quattro Plus is just the new version.
MICHAEL Z  In my opinion, the Advanti Quattro are stiffer fins.
