About Mares Plana Avanti Tre Full Foot Fins

The Mares Plana Avanti Tre features a soft anatomical orthopedic foot pocket, and mid-sized blade with three channels for optimal movement of water during the kicking cycle. Mares Design 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, superior comfort and performance. Tre is perfect for travel to warm water locations. Upper and lower stabilizers help transfer energy from the foot pocket to the blade. Fin gives an easy kick for extended snorkeling time. Super-channel is designed for the diver who wants the perfect blend of power and efficiency in one fin.

The blade design with a large central Super-channel and two traditional lateral channels provide excellent thrust while maintaining hi-efficiency and minimizing leg fatigue. Fins are manufactured from tecralene, thermoplastic rubber and have an easy grip heel pull tab for donning and doffing of fins. Open toe design for added comfort. Overall fin lengths are from 22" to 26.8" (56 cm to 68 cm) and weight 2 lbs. to 3.1 lbs. (0.92 kg to 1.4 kg). Available in multiple sizes and colors.

Good Fins!

These are very good fins for snorkling and SCUBA diving. I was looking for fins with blades that provide good power, but not so stiff that they would wear me out. These have proven to be exactly what I wanted. The slight looseness in the foot pocket has not been a problem. The only problem was in sizing as the website only shows letter sizes with no reference to a numbered size. From my experience, I can tell you that Large = Size 8-9 and X-Large = Size 9.5-10.5. The PFF Guarantee for ...

Not satisfied

These fins impressed me at first. They fit and worked well. After less than two years, one of the foot pockets tore. I pursued warranty service and was told this will take 5-7 weeks. I ordered a second pair of the same fins to use in the meantime. When I started using them, I realized how soft the fins had become after less than two years of use. It wasn't the foot pocket that had lost its stiffness, rather the entire fin. I only used the fins once in a while for the first year or so, ...

Excellent Service!


from Katy, TX, US

The personable customer service I experienced with Leisure Pro surpasses that of many. They stayed in contact with me until my order was received; providing updates on availability and delivery - promising me that I would have my order on time and I did! My husband was thrilled with his Christmas gift! Thanks! Happy New Year and many blessings to you all in 2017!


Not your ordinary snorkeling fins...


from San Francisco, CA, US

I have had a pair of these Mares Plana Avanti Tre Full Foot fins for years now and I just purchased two additional pairs for my daughters, ages 18 and 22. We are avid snorkelers and I wanted to upgrade their equipment. On a recent trip to Curacao, we snorkeled off the beaches of Playa Porto Mari, Playa Lagun and Grot Knip, often going as far out as the "drop off". These fins are a "step-up" from most of the commonly available snorkeling fins, but they are a pleasure to use. They have fantastic speed and quick response for staying safe near rocks, surges and currents, and of course, are great for those long swims back to the beach. A bit bulky to pack for a trip and costs a little more than ordinary snorkeling fins, but definitely worth it! Thanks to Leisure Pro for their efficient service in getting the fins to us on time, since I had to exchange the first pair for a smaller size for my older daughter, then order fins for my younger daughter after her fitting. Both girls are size US 7-7.5 and found the smallest size available a comfortable fit.


Bought the for Underwater Hockey


I bought them for Underwater Hockey. I swim super fast and they are comfortable, Cons. It´s the smaller size and its a little big. but I can handle them. Love them in blue :-). Can use them for snorkeling too. They are light weight and not too big.


Snorkeling fins


Good quality. Comfortable. "9 1/2 to 10 1/2," but I am a 10 1/2, and they are loose. Don't, however, seem to fall off. May have to wear socks.


Been using these full foot fins for 20yr


I have used these tres full foot fins for years, had to go a size larger as they were a little tight. With the slightly larger ones had to add extra socks; but it is better than before.

Shopper  Why Did You Choose This?
CRYSTAL B  Quality of product and speed thru the water.
Duncan L  Need quality combo fins for scuba and snorkel
GARY R  excellent travel fin, lowest price on internet

PETER H  I love these fins, not too long, not too short, very flexible. I use them to Scuba and Snorkel. My feet tend to cramp using heavier fins. I have two pair. Use sometimes with socks, sometimes not. I'm size 11 shoe - Fin 2X-Large.
Shopper  Hello, you have weird sizing. Which size is 6.5-7.5 and which is 8-9? Thank you!
JEROME P  The sizing on these Mares fins IS a little strange. I have size 9.5 feet, medium width. I bought size 6.5-7.5 Avanti Plana Tre Full Foot and later Avanti Quattro Full Foot fins and they fit me perfectly, with enough room for 2-3 mm neoprene socks, which I find necessary to ensure a snug fit and to avoid blisters. I learned about the weird sizes from a fellow underwater hockey player. Both of these are excellent fins by the way! I hope this helps with your purchase!
MASARU K  Yes, I agree that the sizing is not easy for these, but I've purchased a few pairs from Leisure Pro and their exchange policy is great. My daughter is now faster than me in the water! Anyways, I wear a men's size 8-1/2 US shoe and the MEDIUM Mares Plana Avanti Tre Full Foot Fins fit me well. I believe that this MEDIUM fin will fit those with up to a men's 9 US shoe size. Good luck!
Shopper  what is the weight of the fin?
KEN H  I don't have a way to accurately weigh them; however I would put them in the light travel fin category, if that's of interest.
MICHAEL M  Each fin weighs 1lb 6oz/ 622g
