Not bad! It is a pity you don't have a photo in action 
It makes a good blade angle (just in the wrong direction though). It reminds me of the Stiletto Run organized regularly in different cities by the Glamour Magazine. The heels must be at least 7cm high. The performances are rather amazing - I remember at the 80m sprint in Berlin, the winner did it in 12 seconds - I am not sure if I could do it that fast in sport shoes. And in high heels I wouldn't manage to get farther than 2 steps.

no picture, sounds like the ones fastened to the lower shin though.
hehe it would be hilarious to see the stiletto fin in action!
actually, i was wondering if a footpocket that had support from the foot up to the shin had been invented by someone?

Good catch. Thanks for the contribution!
Ah, I know hat you mean! C4 Falcon carbon blades fixed on Elite PRO Carbon ski boots! Good idea. I have to try iticeselkie said:
When not that, then there are couple of fins in previous posts that are fixed to the shin - for example the Freedom Fins, Shin-Fins, or the Farallon fins.
RE: the green force fins on the top page, I actually own a pair (except in black). I've never used them for freediving, but they work well for scuba. They have a higher displacement/lower frequency kick than the shorter force fins (which I've also owned, used, and HATED, mind you). So they should be better for freediving than the other FF's that are sold. Having said that, if they do turn out to work for freediving, they're indestructible and would make a nice backup pair at the very least.
eyeline - quality swimming goggles and equipmentI found these at the local mall they look prety funky.
Hey Trux, from your first post, the dolph-fin monofin, I've been thinking about a radical type of monofin (probably not practical but...)
Have you seen a monofin, which curves out like the dolphfin, but has only a small bit of material in front of the feet, so appearing like a lunate swordfish tail rather than a more rounded trout tail?

This would perhaps allow faster more efficient propulsion, but require more hydrodynamic outline.

Really, I guess a marlin tail monofin style:

for a description of another heroic commercial failure, Caravelle fins designed in 1963 "with a detachable polypropylene blade and foot pocket of rubber that essentially worked as galoshes. These rubber galoshes made it possible to walk to the shoreline, and then mount the blade onto the galoshes to continue diving."

I have put most of these fins and some other ones into the new version of my Collection of Weird Fins on my website. I write about the new website, aslo including Freedving Media Base and Anea Training Manger program in this thread:

I used these fins for over ten years. Not only were they very comfortable in the water but they fit well in a suitcase. Great for someone who travelled a lot.

Hi you all.
I have two friends that developed a new fin concept (at least never seen nothing alike). To try their idea, they built a prototype with the materials that they had available and the thing doesn't have the best look but they wanted to test their ideia.
The test confirmed their believes nad the have 40% more efficiency than the plastic fin that their compared. In the same course, the plastic fin needed 12/13 strokes and the new one only 6/7. they both tryed several times...
The prototype was sent to a portuguese spearfishing gear manufacter to make some tests and see if they wanted to produce it. They promissed to keep the concept a secret and they were very sorry for my friend and for them as company since the idea is great but theire a small company and can't embrasse the production.
So i'm trying to make this happen. My friends and i don't seek a fortune or to get rich with this. If we can sell the idea it's great but most of all we'd like to see this happen and to get this to the world.
Just to give some idea, the normal fins compress water i some parts of the blade and that energy isn't used for porpulsion... with this concept, there's no water compression, just glide
So i and my friends would aprecciate any help withcompany contacts or any info on pottencial interested companys.
I'll start to contact some companies
thanks

Fernando you make us really curious here!
I hope you'll find your producion company.
From a psychological point of view, I think it's wise to give the fin a 'traditional' look. I'm sure it will help selling to both the manufactures and the end users.
The glide word is one that havily resonates with me and many other freedivers.
Best of luck!

the look is close to the traditional (footpocket and blade)... the prototype isn't just all pretty and glossy... It's like in cutted wood versus sanded and polishe wood
thanks for your support

What would you say are the positive points your design has, perhabs even compair it to the carbon 'class' of long fins?
the positive points are no splah on surface, less resistance to water - less efford for the same distance, less stress on joints (foot and ankle)...
if done with carbon, it will be far superior to carbon long fns... We'll make a test against my C4 mustang
Could your design also be applied to monofins?
Yes, but the footpockets need to have diferent characteristics (althoug the look isn't very diferent then usual)
I quess pictures are out of the question?

Wel, Wel Marginatus, You have defenitely got my attention!
Get your patent quickly so we can see the geniuous of your design
I'm sure many big manufactures would not like your design, because it will make their old products look acient. Perhabs partial manufactureing and self assembling may provide a way, provided the design is not just one piece.
I think you'll end up producing them yourself facing the global corperate world.
Don't get discouraged, be as persistent as Eric Fattah, perhabs even team up with him? I would love to see the inovative people team up and make room for each other's great inventions and products.
Find inovative ways to market your products, have media coverage, I'm sure a few World Records and topathletes endorsments would help creating acceptance and confidence. People are trained to follow experts. Without questioning.
Best of succes,
Kars
