Unisex Adults Avanti Quattro + Diving Fins - Durable Efficient Versatile Open-Heel Scuba Fins with Four-Channel Design & Bungee Strap

Everything is fantastic! Excellent fins, fast shipping, great price. Thank u

these fins are great. fly through the water with ease. love the bungee strap. easy to take on and off. even with full dive gear on and on a rocking boat. fins stay where they are supposed to. Have used these on many many dives. dive buddies and groups always say it is very easy to spot me under water because of the bright green color. have even had some friendly aquatic animals follow along. perhaps they like the color too. I wear U.S size 10.5- 11 shoes. I use the large fin and 10 mares 2mm bootie. the XL fin was way too big. the 11 bootie kinda worked but the 10 is a lot better and snug fit. the 11 bootie felt like the water could pull it off.

I've used these fins a couple dozen times now and am impressed. I read a couple reviews on other sites that suggested leg cramps were caused because of these. I haven't found that to be true, thus far. What I love: the bungee strap! In and out of the boat is a cinch with these straps--I'd never want to go back to a buckled strap. Also, these are very lightweight compared to other fins I've used. They have enough room in the foot pocket that they can be worn with boots, but they are also closed enough that they can be worn with just dive socks/booties if that is preferred. I typically dive with Cressi Palma 3mm "boots" (socks, really) and they work great with these fins. Cons: the white color gets marked up quickly from the black rubber accents. Also, don't be tempted to wear these barefoot. Most people don't wear open heel fins barefoot, but I've done it a few times anyway with different fins and was fine. These straps will not allow for that. Addressing the cramp issue--I feel like that is much more a problem with diet, exercise, and technique than it is with a particular fin. The same can be said of any sports related cramp. I've cramped once in all my diving, and I was just coming off leg day at the gym and wasn't hydrated. Don't be afraid of these fins because of a few cramped-leg reviewers...I honestly do not know how these would contribute AT ALL to cramping.

I've been diving for a while and have had other fins. These fins are terrific. Moderate flexibility, comfortable and easy on/off. The only caveat is you need to have moderate leg strength, not spaghetti legs. They give good thrust and equally good for sculling. The bungees that hold them on your foot are very comfortable and have a handle to make removal easier. Note that I wear a 3mm boot so if you go barefoot, that might be a consideration. Overall, I am very satisfied and would recommend them. BTW, I bought the dayglo lime yellow/green which is easy to see in the water and on the boat.

These are some really nice fins. Produce great power yet in doing so leave you a bit more tired than you may be from some other types of fins. So if you're worried about cramping or if you'll have the strength then maybe hinged or split fins would be better for you. But if you're willing to put in the effort and feel that your body can handle it these provide great efficiency returns for the effort put in. I find these to be the fastest fins I've tested in getting ready for the 800M snorkel for the divemaster exam. I've tested Tusa split fins, Scuba Pro Seawing Nova's, and Hollis F1's. These are the fastest of the bunch. I feel like the Nova's do a better job in providing good thrust while making you less tired. But if thrust and speed are your goals these win. Conversely, these fins do a fair job of alternative kicks but they are not as good as the Hollis F1's. However the F1's will leave you even a bit more tired yet than the Quattro Plus... So if you're looking for good enough speed and low effort input for a flutter kick the Nova's are great. If you want flexibility to do multiple different kicks and want good speed these are a great choice. And if you're looking for ultimate flexibility and a bit more physical effort while trading a bit of speed efficiency the F1's are great fins. All very nice options in their own right its just down to what is important to the person and their needs as a diver.

I've been scuba diving 25+ years. These are the best fins.

I wear a mens US size 7.5 generally. I went with a size 7 Mares Flex DS 5mm boot and chose the size small fin based on the chart and not going up a size to accommodate the boot. Just fit! Boot slides in and leaves 1inch hang. Foot in the boot, it hits the sides of the cup just to qualify as a snug fit towards ankle while leaving toe wiggle room in the box. If I had moved to a regular it would have been sloppy loose. Fins came with strap extenders to help if strap feels tight. If you have super thick boots or an incredibly wide foot... Go with the regular. Side note.. I def got a pair of returns. They are in great condition so I'm not mad and understand people try them and return them. Consumers.. be kind, put the parts back in the little baggie, don't tear up the warranty and info cards and stop stealing the sticker!

This is my second set of these, my first pair lasted 6 years of diving all over the world- easy stuff in Belize, ripping currents on Polynesian atolls and sea mounts in Socorro. The blue pair in the photo. Those got lost off the back of a livaboard in a storm in Papua New Guinea after the mooring line broke and we almost lost the boat. They were starting to wear a bit at the bungee attachment points, but to be fair, I think it’s because they got mixed up in Socorro for a day and another diver with much larger feet crammed his giant foot into them. Yes, you can get a bit more power out of Cressi or other long skin diving fins (have fun inside a wreck with those, or packing them) and a lot of fins will give you as much fine control, but nothing else on the market gives you the control with the power. I got stuck with a loaner pair of fins - Scuba Pro go travel fins in PNG and on the first dive in a current I missed the Avanti Quattros. If you use them a lot, you’ll eventually wear out a bungee strap, but it’s a wear item, so buy a spare.
