About Mares Avanti Quattro Power Full Foot Long Blade Fins

Mares Avanti Quattro Power is the ultimate Channel Thrust fin for speed, power and fun in the water.

The best all-around full foot fin for diving. The Avanti Quattro Power is perfect for warm water divers, snorkeler's and free divers that want ultimate power, comfort and speed. The choice of demanding scuba and free divers, who want comfort combined with extraordinary performance. 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. Latest development in Channel Thrust is the Super-channel. The blade is designed with a large flexible central Super-channel propelling water-flow more efficiently down the fin blade instead of letting it spill over the sides for optimal performance and minimal diver effort. Vertical ribs that anchor the blade through the kick cycle to eliminate side to side wobbling effect, keeping your kicks stable and reducing power loss, and will help eliminate ankle-twisting phenomena. Fin comes in three sizes, is black in color, overall fin length is 28" to 29.5" (71 cm to 75.5 cm) and weights 4.2 lbs to 5.2 lbs (1.92 kg to 2.35 kg). Fins come with a 24 month limited warranty.

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

I have owned my pair of Avanti Quattro Power FF fins for over 12 years. They are outstanding to this day. I used them primarily for boat diving since not wearing a boot is required - long walks over a reef or along a beach would suck barefoot. I have to be honest, the initial phase of breaking these bad boys in was so painful. However, it was not too long before I completely forgot about the blisters and discomfort (yes, while diving) and just enjoyed my dives. I used the Mares Quattro Open Heel fins to teach, but if I could get away with these FF fins, I will pick them every time. They are comfy without socks, fairly easy to slip on and off - I can usually do it standing up at the edge of the dive platform on a boat right before giant striding into the clear, blue water of the Pacific. If you are new to these fins, don't be discouraged with the blistering break-in process...these fins are worth every waterproof blister bandaid you will ever buy. 1000% worth it.

Questions about this item:

A M  Hello, I was happy to see Mares finally added a larger 11-12 size to Quattro Power line. I typically wear a size 11-12 fin, as always seem to fit nicely on my US size 13 foot. However, there seems to be some confusion whether, or not, these sizes are US or UK. In any event, my main question is: Will these fit comfortably on a US size 13 foot? Thanks, Andrew
MILLARD S  My son who is a US size 13 wears these fins with a 2mm neoprene sock and they are a good fit for him.
A M  Thanks!
Shopper  I am a woman's size 8. What size fins do I buy?
KEVIN F  I would recommend 6.5-7.5 for you. However, it is the smallest size and they may still be too large. As an option you can wear it with a neoprene sock to fill some room and add comfort, if needed.
Shopper  I wear 9-9.5 men's shoes, what size should i get?
RICHARD G  My shoe size is a men's 11. I wear the 8-9 fin with a thin neoprene sock. I use it primarily for underwater hockey play, although I would also wear it in the ocean.
