My feet are slightly too large for size M, but size L is loose enough for fins to pop off when hit by a lip, so a tether is essential, and probably a bit of padding, socks, or booties. This will be worked out. For me, sizing is rather similar to DaFin, which also pop off and require tethers. I can fit a size M with DMC Repellor, L in MS Viper, and 10-11 in POD Fins 3-PF3 Evolution, all with less risk of fins popping off.
The Leblon Flex fins are comfortable and have caused almost no fatigue in the first few days of use, which follows a summer with a lot of inactivity, including a recent, bad cold or sinus infection.
I am impressed at how easy it is to swim around the beach with the Leblon flex model. Just kicking while being on my back with perhaps a bit of backstroke was faster and more efficient than I'd been accustomed to. The Leblon has distinctly more thrust than MSViper, DaFin, or POD (right in the photo) that I've been using.
Being a large and heavy fin, the Leblon is a bit harder to walk with than the others, but the it's completely at home once in the water. The Leblon has ridges on the bottom of the foot pocket to help with traction. The drain holes, unusually on the top side, quickly clear out sand, which at our beach has a lot of shell fragments. Fins with round drainage holes clear slowly,
Catching little waves, no more that 1 meter, took a bit of re-learning. Wait farther back: It's easy to accelerate like a board rather than try to push off from the bottom as the wave is breaking. We should have 2-meter waves in a few days.
My guessing is that learning to use the Flex model to full effect will take a while. It means faster, better beach swimming. I haven't yet tried them with a camera, handplanes, bodyboards, or surf mats.
I've used my fair share of swim fins (Churchill Makapuus, Slashers, DaFins, Voit Duck Feet, Viper V-5s, etc.) and these definitely produced the biggest shock factor when first kicking around with them. While the level of ankle/leg fatigue from 15 minutes of use is definitely increased, the amount of propulsion generated from a few short kicks is incredible. I spent a day in 3-4' sets switching between my Leblons and DaFins and couldn't stop commenting on how the DaFins felt laughably flexible and weak after using Leblons for awhile. A strong dolphin kick with these was allowing me to enter a wave ~3-5 yards sooner than with the Dafins. creating for some special lines.
A quick warning - don't overestimate your leg strength or experience level when choosing these. I am rocking the Originals and could barely see myself moving up to the Pros (and quite honestly wonder if the Flex line would have been more appropriate). That being said, no regrets at all with my purchase. I will likely get another pair of these in a size up to accommodate for booties in the winter season.
I have been ridding waves for 5 decades . I have owned and used the following fins .
Churchill’s , Duck Feet UDT ,Reedly , Viper V7, Force Fins ,
Toobs blunt cut , Dafin ,
Leblon soft and mid flex .
I ordered the Leblon fins because the long side rails caught my attention .
After rideing waves with these fins I can say from expirence that the Side rails really help in holding in on a step wave face . I use them for body surfing and mat rideing .
They are very powerful equaling my
Duck feet UDT s . Which are the most powerful fins I have used . And yet they are much more comfortable than the UDTs.
I wear a size 12 shoe . I ordered the large size . They were a bit lose but I wear a 2 mm fin sock with them and they work fine . I do the same thing with my duck feet and duck feet UDTs.
Before deciding on my first pair of Voit Duck Feet, I read countless reviews and online articles. Not long after that, a pair of DaFins showed up in my surf bag. Thinking I was done buying fins, I quit looking. Well, intentionally, anyway. Then somehow I happened across Leblon Fins. I saw an ad on UKMatSurfers.com for a pair of the Leblon "Original" model and was intrigued by the design.The more I read about them the more I had to see for myself if they really worked as well as the reviews were saying. I had to have a pair. But couldn't decide between the Flex Model and the Originals. Leblon recommended the Flex Model for those "new to the Leblon experience" due to the Originals extra stiffness which they said required a getting used to period, also mentioning they could be just too stiff for some.
Now what do I do? I want the Originals but don't want to find out I can't handle them. Or do I take the recommendation of the Leblon folks and order a pair of the Flex Model. Oh....wait a minute. They have a 10 day return policy. There you go, that settles it. I order a pair of each in size large.
I am a size 10.5 with a super wide toe box. The large were a tiny bit loose on my feet until I put my fin socks on. Then they were PERFECT! The foot pocket on these Leblons is one of the most, if not THE most comfortable foot pockets I have ever worn.
So now for the real test. How do they work? Simply put, these are some powerful fins. I didn't have to think too hard if these fins felt different. With only a few kicks, the difference in propulsion between these and my other fins was obvious. Getting out into the lineup, and getting into the waves earlier was a new experience with my new Leblon Originals. And the kicker was that my wife, Kathy, watching from the beach, could tell how well the fins worked for me.
After two hours was I sore? Yes, a little, mostly on my ankles. But it was a good sore...
Here is my feed back for the Original model.
First I've been training in a pool for getting use to it for a while.
It's stiff but if you are used to DaFins for example, it's not so challenging.
The Medium size fits ok for my 9 us, it was a bit narrow in the beginning but is becoming better with time(I have slim arched foot) now I feel comfortable like at home.
Today was a perfect day here so i was finally able to try the fins in perfect glassy conditions.
I give it a 5*, it's really powerfull and it gives you ability to drive high on the wall and keep differents trajectories, resulting in maximum speed and longer runs
To make it simple, with another fins I feel I'm "falling" down the curl (with style sometimes)
with my Leblonfins I feel I drive !!!
And I can't notice any dragging in the surf, just a lot of drive and speed.
I would really recommand these fins to everyone used to finswimming and good shape, if less in shape, perhaps the flex model suit better
I'm so happy I got this fins , thank you jsc Mauricio making this possible, I hope oneday we can find leblonfins in all surfshops.
Cheers from Hossegor area, southwest of France
The size of the find I purchased are mediums and they are a little snug so I can eliminate socks or booties. The pocket is so comfortable that I can surf in comfort without blisters from the find binding my feet. Really stoked about leblons
I am a dedicated performance bodysurfer having ridden many challenging waves like Wedge, Itacoatiara, Supertubos, Blacks and many more. I have used a variety of fins extensively before finding LeblonFins in 2016. The prior models have been Duckfeet, Vipers, Churchhill, DaFin, DMC. LeblonFin has by far way more thrust than any other fin on the market today. Most recently I tested the Flex model at big Wedge on August 17, 2018 and the fins performed fantastically in the 20 ft plus size waves. LeblonFins are made specifically for performance bodysurfing in mind. For full disclosuer, I am a LeblonFins team rider.
These are my second pair of Leblon Fins. I really like how much power you get! I'm the only one in Oahu Hawaii that I know of that rocks these bad ass fins in the line up! Aloha!
Thanks Leblon for the quick delivery of my fins. Can’t wait for you to bring out more sizes! Excited to hit the water.
I normally wear a 8/8.5 shoe normal width. The tow box was a bit narrow, but may fit better with more usage. Great push and takeoff. Could tell a difference almost immediately from my other fins while body surfing a large NE storm swell we commonly get in NE Florida. Maybe add a bit of padding (could be very thin) to the top of the foot casing for added comfort? I’m usually in the water for hours at a time. Again, may fitt better with time but, I did blister on my first few usages. This was never a problem with my vipers. But as far a performance is concerned, head and shoulders better than any fin I’ve used for body surfing.

These are quite heavy & large compared to my MS Vipers I’ve been using. I’ve tried Da Fin (uncomfortable), Dmc Repellors (broke two after a few sessions), kicks (not strong enough for hand boarding). Leblons provide great forward movement. They also seem to wag from the front of my foot, (I wear a size 11 to 11 1/2) making them a bit awkward when standing and moving in the shallows. The largeness however goes away when I’m kicking. Comfy fins! A great choice for specific conditions.
Like the design, even though my foot falls in between sizes. They work remarkably well, generating great torque.
These are big fins, and that means A LOT of power. I definitely wouldn't recommend them for someone starting out - your legs will not thank you for it. These are for those bodysurfers that have put in some serious fin time already. They take a bit of getting used to and I think will come good after some more time wearing them. I am yet to figure out the best conditions for them, but I am stoked to have them in my fin quiver - I can see them being really good in big days, getting into a wave early and hold the face with the bilateral rails - this could be a bit of a game changer. They are well made and the design has been thought through well. Glad to have them! 4* as I haven't had enough use yet to give a full 5* (long delays on shipping and then delivery - but that might just be cause I am in the UK).
I've always been an advocate of both the UDT Duckfeet and Viper V-7 for powerful thrust in punchy surf with nasty, rip-filled currents. The past two days, however, I used my new Leblon regular flex fins in 4-5 foot San Diego beach break, and was incredibly impressed with their comfort, thrust and tracking on the wave face. In Carlsbad, the waves from the south swell were clean and round, and an accompanying long shore current that made swimming challenging. However, the Leblon fins performed perfectly! I will add the Leblon fins to my group of previously mentioned favorites and have a perfect bodysurfing "trifecta." These fins could easily become my daily favorite, however as I enjoy bodysurfing tradition, and experiencing fin variety and nuances of different models, I will add the Leblons my quiver!
One possible suggestion: I would like to have a thicker heal strap for both longevity and security
After 20 mins, could not kick anymore. Just too thick and did not flex enough, resulting in paim in feet and calf. I traded with friend, he agreed.
Just started on the LeblonFins flex-I am primarily a body surfer and so far am loving them-I have very wide feet and struggle with Dafins causing cramp-they are the best fins i’ve ever had though-power and comfort. One issue to watch-theoretically the large is US 11-13 but as a UK 12 they fit but only just (but I have got long toes) highly recommended. No cramp, early entry into waves and a greater ability to hold the line!
My Leblons arrived just before I left on a trip to Baleal, Portugal, so my first time wearing them was when I stepped into the water to swim out into the lineup. I wear a size 12 US, 46-47 European size and I have wide feet. The Large size Leblon fins fit perfectly and I did not need to wear neoprene socks for comfort. I would need a larger size if I wanted to use booties (I use XL Churchills with 3-4 mm booties in winter). The sand-out chutes (or whatever you call them) did their job as soon as I began kicking, which has good since I picked up a lot of medium-sized gravel and sand after just a few steps out into the rip channel. The sets were coming in head-high and fairly clean, so it was nice to be able to duck dive and just wait for an open wave face slipping through the local talent. I’ve been happy with my Churchills and DaFins, but the Leblons definitely delivered more power per kick cycle and it was easy to get in position on the wave for some fun rides in the pocket.
I have been using LeblonFins for a short period of time and I can guarantee that it os the best swim fin for body surfing. The incredible speed that LeblonFins provides is second to none. I strongly recommend LeblonFins for those who aims improvement in body surfing. Your body surfing session Will change forever (for better).
These fins are the most comfy, powerful fins ever. I have used the Original and now the Flex version for mat surfing, and while they are both great, the Flex fins are my preferred model. I cannot recommend these fins highly enough.
As everyone who purchased LeblonFins wrote,
they are powerful but comfortable fins.
I feel I got a trustworthy buddy in the water.
I would like to describe the size of the medium fins, for people who have a bit small foot and consider the purchase of these fins.
My shoe size is US Men's 7 1/2 - 8 (26.0 - 26.5 cm),
that is at the lower border of the medium size of LeblonFins (8-10).
My other fins are Viper V-5 Medium (8-9) and DaFin Medium (7-8).
For Viper, I need fin pads and neoprene socks to make them fit.
For DaFin, fin pads and regular socks are enough.
For LeblonFins Flex Medium,
1. neoprene socks
2. fin pads with regular socks
3. fin pads/regular socks with a strip of neoprene inserted between the fin strap and pad.
1. Using neoprene socks makes some pain on my arches of the foot for long use.
2. Fin pad ( regular socks) is a bit loose.
The straps are getting to be pulled down when I kick hard during the riding.
Then, No. 3 provides a nice fit and also comfort.
I hope this information is helpful for some people.
The makers of Leblon Fins are dedicated to a new level of performance. Several years of consultation with engineers, scientists and athletes went into their design. They also take cues from the ultra-fast sport of finswimming. The leverage on the blade is very different than any other fin I have tried -- seemingly more emphasis on legs and core, and less on the ankle.
My very first session, I was getting in higher, tighter and faster. Major thrust off-the-line, and fully comfortable for swimming, these are the new standard. I just hope you all don't get your pair too soon, because for now I have a serious edge in competitions!!
The first time I used the fins was in the pool. I was absolutely blown away by the velocity these fins are able to produce. Especially when you
Dolphin kick. The next time I used the fins was in the ocean, body surfing. The added gain in velocity helps you catch more waves and gets you in to the critical part of the wave earlier. Right away, I noticed the grab of the of the sides and how they help hold your trim line when sliding down the face of a wave. These fins are amazing!
The thrust of these fins are quite a bit more noticeable than others in my arsenal. Unfortunately, my 10.5-11 foot did not fit 11-12 size fins. My 2 other fin sets from other companies fit nice in the 11-12 size. Easily a 5 star fin if I didn't have to make alterations with superglue and neoprene. Let me know if you ever change your sizing structure, I'll wear these out eventually. These fins are some of the best. Your videos and articles on your website changed my takeoffs in the waves so much. I highly recommend these fins.
