I can't even.I have no idea what you mean and I’m a mathematician.
“Science doesn’t prove”?
Mostly off topic, but looking online it seems there may be some controversy regarding "scientific proof". Feel free to look it up. I was taught (and it made sense to me) that "science doesn't prove" (except math).I have no idea what you mean and I’m a mathematician.

Ok..There is the small issue of $300,000 required for the tooling to make the commercial version of the fins. This is why I am talking to everyone. I would hope to raise that funding through crowdfunding. It only takes 1500 divers at $200 each to get them each a "final" version of these fins. No-one is willing to take the risk without getting great endorsements or actually trying the fins first. So here we are. I have 5 pairs of fins and simply cannot get them to everyone so I am working on making a bunch more. Then I will start a road show where I will take over a dive boat in various locations and offer the fins for trial. Record the results and present them to you. The videos on my website is the result of early forays. There were certainly more people who have tried the but for various reasons I was not able to get video of them. I have published all of the videos I was able to capture and have not edited out any negative comments. By watching them you will see some have some reservations but usually it only is based on the fact that they have only tried them for a short period. Of all the people who have tried the fins the worst review has simply been neutral.
How many reviews will it take before this group believes they are real? Honestly, there is no reason for me to claim something which is not true. If it is not true it will be found out. One cannot build a business on that.

As a more on topic follow up question: have you ever seen scientific proof of fin claims?
Of Course. It is in everyone's best interest that no claim go unproven. Here is the link to the testing program.Can you provide real proof of this? I mean scientific proof not another video in a pool.
Yes. Your testing was several years ago. Thank you for your candid response. I have made substantial improvement in the materials since then and other tech divers have discovered the frog kicking technique which does work. No doubt, really powerful and easy fins can be designed, but as you stated, they would be quite expensive. I consider these the sweet spot between all these factors. Please let me reiterate that these are really originally designed for general open water divers. The goal is to allow them to swim longer with less effort and less pain. The military should have interest in these too since they have to push or drag large packs long distances. That is a place where efficiency is nearly everything. See you at DEMA.So when I ran EDGE/HOG I looked at and tested these fins, in the water.
My take is pretty simple. They work. If you wanted to design an efficient fin for the recreational diver that does a flutter kick, these work quite well. I like them MUCH more than splits. I also like frog kicking much more than flutter for a variety of reasons but that aside I'm not quite brain washed enough to feel that flutter kicking isn't ok. I would prefer a good flutter over the bicycle kick too many certified divers seem to have mastered in the OW class.
I really didn't find these fins to frog kick at all well. If somebody considers a sorta sideways flutter a modified frog kick they may believe they work for frog kicking. I don't.
My only concern regards these fins is durability. i am not convinced that based on the samples I saw and existing techniques for molding different fin compounds that they would hold up. I do think there is another way to achieve the same effect thru mechanical engineering but it would be really expensive and the fins would cost $400 or so.
This product shows promise for the intended market.
I have absolutely no idea. But here's one I found with minimal effort. If you want to criticize it, write to the Publishing Journal.

You gotta try them. Will you be at DEMA?Outrageous claims require a modicum of proof. Not a paper in Science.
The current fin manufacturers apparently have no interest in scientific data. An earlier version of my fin was tested by a major manufacturer on their kicking machine and they told me it performed better than theirs but that was not sufficient to cause them to throw away their multi-million dollar investment in their current product. It is much easier for them to make them pretty and coin some fancy phrase and market the heck out of it than to prove their claims.It kind of funny to ask that from a startup. I haven’t seen any proof on fins from any manufacturer.
