Yep, one use is not enough. I love mine. And they are the regular Force Fins. Not the uber-cool high end ones. I have a shattered ankle that still has bone fragments floating and a detached ligament in that ankle, plus no cartilage in either knee joint. These are the only ones that don't cause pain during or after use. I fossil dive in rivers and we have strong unpredictable currents here in Kuwait. I have never had any struggles. There is a learning curve though just to get the feel of their movement. You tend to want to feel the resistance of the water, and you just don't with these. It can be weird feeling at first.

At any rate, if you don't like them, don't use them. I don't go fussing about fins I used and just didn't care for. Everyone has different needs and preferences. Just use the ones you like.
 
I'm not at all surprised, nearly everyone that "tries" them for the first hates them, but for some reason after about 4-5 dives the same people will not give them up

Because after they have had the time to do 4 or 5 dives - the bank statement has arrived and they realized how little is left in their account and they have no choice but "loving them" :shakehead

Give me a $100~ pair of jets, slipstreams, etc or longblades and they'll satisfy any diving needs I'll ever have.
 
They are on my wish list - just harder to buy locally with spring straps (and it took long to find out what size I need - XL - ; I had to search for somebody having L, XL and XXL in order to check). The sizing was strange, as my current fins (twinjet max, nice enough) are M.

Here you go....the price have gone up, but they are still on $79.00 and you will swim circles around your buddy and the FF :)

CONTRARIAN ALERT!! I will save my complete report until i get back from COZ next week. But here it is thus far. They are expensive, but in my estimation not any more then the other new 'wazooo' style of fins. I was VERY skeptical at first, but after many hours of a pool tryout and an moderate ocean tryout. I LOVE them. Yes, I had to modify my kicking style, but not that much. They are lighter, stronger and easier to use on the leg muscles then oridinary fins. I great improvment. More after my Mexico trip.
 
or they forget how it was with other fins before and start to accept the situation..

Any kind of review is useful when somebody is looking to buy something. If all reviews would be good because bad reviews are never posted, it would be hard to learn the pros and cons of some item.
 
there hasn't been a fin tested in any real scientific manner that will outperform them.


And they have never outperformed any other fins in a scientific study. Has there ever been any fin tested in any real scientific manner? I have no idea how a test like that could be done.
 
how many times do I need to go over this, YES, there was in fact exactly one true scientific study that included ForceFins. it was performed in a flume tank with the diver connected to pulse oximeters, HR monitors, O2 consumption and lots of other instruments. It was performed by the University of Buffalo Department of Physiology and Biophysics. The study clearly showed that all divers were able to swim the same speed but maintained it longer, while having lower heart rates and lower oxygen consumption.

and although follow on studies performed there, that have included the new split fins have confirmed these results, even though ForceFins were not included in the follow on, other fins that were in both confirmed that nothing on the market matches them. From a conversion I had with the leader of the studies confirmed for me that they have never seen anything that approaches the efficiency of the ForceFin. He further elaborated that they do not understand why they ForceFins are good as the equations they have can not even describe their motion.

The most telling conclusions that he has published included (speaking of all fins, not ForceFins)
1) "the divers invariably ranked the stiff fins as the best and the flexible fins as the worse, which did not correlate with the objective evaluation of these fins."
2) "The transition and recovery phases provide little thrust, and in fact, added to the overall drag, and had to be compensated for by an increase in kick frequency to meet overall thrust requirement"
3) "it would be advantageous to maximize the average thrust during the recovery... However, the anatomical joints and muscular power a human diver uses during fin swimming (hip, knee, ankle) and body attitude in the water does not allow symmetrical range of motion when flexing and extending. This fact leaves fin improvement to increasing thrust in the power phase and minimizing drag on the recovery and transition phase"
4) "fins where the successive [trailing edge] segments that progressed to 90 [degrees] to the horizontal produced the most thrust during the power phase.

what does all of this mean, well it means that a reasonably flexible fin that you can flex to nearly perpendicular during the down kick will provide the most thrust at lowest work. Efficiency can then be maintained by having the fin minimize itself and therefore its drag for the recovery phase. In other words... do what ForceFins already do.

I don't doubt you for a minute. But do you have a link to the study. I'd just like to see the details for myself. I just hadn't heard of it.

Thanks in advance if you do have it.
