Comments about Mares Avanti Quattro Power Full Foot Long Blade Fins, Black:

i am a size 10-10.5, and they were slightly big. used a 2mm neoprene sock, would have fit a 5mm too.

slightly heavy and long for caribbean travel, but worth hauling them. GREAT pair of fins. so fast and very efficient.

These fins are great. They get you through the water fast. They are somewhat heavy for travel. Mine (size 6 1/2 - 7 1/2) weigh around six pounds. Also, I purchased fin socks to wear with my fins because although I wear size 7 1/2 shoes, the 6 1/2-7 1/2 fins were too large to wear without the socks and I got blisters. With the fin socks, they're comfortable, and I don't think you will be disappointed with this product.

I have owned these fins for a couple of years now, before that I used the Mares Avanti Tre (a weaker, cheaper version) for freediving and spearfishing. Prior to shelling out more than a hundred bucks I decided to go scientific about it. I purchased: an Esclapez with a plastic blade, a [$] fiber Omer Pegaso and compared them with Avanti Tre and Quattro. Esclapez had an excellent footpocket but it was a mismatch with a plastic blade that felt like something out of place. Omer had a universal footpocket with removal blades; it was stiff and uncomfortable, not recommended for people with high instep. Mares footpocket was excellent, albeit sizing between Tre and Quattro was different. If you are size 11 and wear a 3mm neoprene sock, go with the largest size for both Tre and Quattro. So my test consisted of two parts: an all out 50 yards diving with registering time an a pulse rate and a 1000 yards surface swimming. For 50 yards diving Esclapez an Tre were out of contention, so the fight was between a fiber Pegaso and rubber Quattro. Pegaso gave 1/10th of a second advantage and about 5 heart beats more per 10 seconds interval. That tells me - you will be burning way more oxygen with Omer Pegaso. Not to mention the comfort level, but that is individual. Of course, the stroke technique is quite different with fiber/carbon blades - more of an ankle work versus rubber fins where an almost all foot is engaged.For the second part (distance swimming) it was no comparison - both Tre and Quattro are way more comfortable than Pegaso and Esclapez. Pegaso is not suitable for surface swimming due to a blade angle - it is a 'vertical' fin for boat drop-offs. So I stopped torturing myself pretty quickly with Pegaso during a second part of the test.So at the end it was no-brainer - Quattro is cheaper, more efficient (for me!), suitable for surface and vertical and way lower maintenance - fiber/carbon blades are fragile. I went below a 100 feet in Quattros and Tres and fins have NEVER been a limiting factor for me. I also swam more than 2 miles during my spearing sessions.For reference: when I was doing my tests, I could do a 1000 yards butterfly kick with a kickboard and no fins in about 20-21 minutes (I was a competitive swimmer for many years), so people with weaker legs might find fiber/carbon blades better. So do your own tests if you can. But if you go off the shore, and especially if you need to swim a long distance to your point(s) of interest, Quattro is by far your best bet. This model has been in production for many years and for a very good reason!Hope this helps, happy hunting!

I used this product as my every day fins to in my dive operation for my personal use.

Very durable but heavy, and when diving every day many times a day sometimes it gets tricky.

Now, they are extremely powerful and excellent quality material. But it did take some blisters to get used to it.

Now I go for a light fin and my Mares Avanti are in the closet.

Would I recommend them: yes. They are a good product if you don't care for them being heavy. Apart from that, they are great for chasing divers around and give you the power needed.
