LeblonFins Size S - Crowdfunding

LeblonFins Size S - Crowdfunding

Regular price $109.00 $59.00

The ultimate bodysurfing fins designed for effortless thrust and drive, with side rails that stick you to the face of the wave, and a comfy foot pocket. Now crowdfunding for size S (US men 6 - 7.5)

All LeblonFins share the same revolutionary shape but are made of different rubber compounds.

LeblonFins Flex have the most flexible blade. We recommend them for most bodysurfers who start out with the LeblonFins. They provide more thrust and drive than any other bodysurfing fin and require less effort.

LeblonFins Original are stiffer and demand that legs and ankles be used to some effort. This model provides you with even more propulsion.

LeblonFins Pro are the most powerful bodysurfing fins in the world, and recommended for athletes with really strong core, legs, and ankles.

You may want to have more than one version in your quiver. The Flex lend themselves perfectly for long, light sessions (e.g., after a hard workout with the Pro or Original), but a pair of Original or Pro is perfect when you want to go hard for a short time, like at a contest or in challenging surf.

At the moment, we can guarantee only one color combination per version: Flex in black-aquamarine, Original in red-yellow, and Pro in blue-yellow.

We may be able to add more colors as a stretch goal, and will keep you updated by email to ask for your preference.

Size S will fit most people with US men´s shoe size 6 - 7.5. If you have wide feet and are on the upper limit, or if you would like to use them with neoprene socks or booties, please consider ordering one size larger.

LeblonFins US men

Our crowdfunding campaign aims at raising the funds to produce LeblonFins in the sizes XS, S, ML and XL. The sizes Medium and Large are already available, and have been enthusiastically approved by bodysurfers, mat surfers and lifeguards.

We need to raise 12,000 US$ for each additional size to produce a mold and the fins ordered. Raising this amount, we won´t make any profit, but only cover costs.

We´re a small, family-owned bodysurfing business, and have invested our private savings into the product development behind LeblonFins. We won´t be able to bring more sizes to the market without the support of the bodysurfing community.

We´re running separate all-or-nothing campaigns for each size on our website. This means we will only produce a size if there are enough orders for it by the end of the campaign. If we don´t meet the goal threshold for a size, all orders will be refunded, and the production of this size will be postponed indefinitely. It´s possible that one size may get funded and another not.

We ship worldwide from our warehouse in Florida, USA.

Shipping costs are calculated at checkout and depend on the weight and packing dimension of your order.

For many countries shipping cost per pair go down when ordering more fins. For many countries total shipping costs are nearly the same for orders of two or three pairs.

If shipping costs for your country aren't listed already, please just drop us a short message and we´ll get it done.

Effortless thrust

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.

Night and day level of thrust compared to what you've grown used to.

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.

Tried The Rest... Now I Have The Best

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...

They run big

The fins are great but they definitely run bigger than I thought
