All it took was watching the tail fins of fish – except that we couldn't keep up with them because our traditional fins took too much effort. Using hard kicking paddle fins can result in leg strain, fatigue and cramping. Because of the kick resistance of a paddle fin, divers often “felt” like they were moving fast. But underwater speedometers proved that these divers were actually moving relatively slow. SplitFins deliver more propulsion with less drag and kick with less effort. Reducing the stress and strain of the kick results in greater sustained speed, power and comfort. Independent testing has also confirmed that the SplitFin design significantly reduces air consumption. Don't worry about how easy the SplitFins are to kick. There is nothing wrong, you're probably already going just as fast as you did with your old fins. Although they work with a variety of kicking styles, you should adapt to a smaller range, more frequent flutter kick for maximum performance. The smaller-range rapid flutter kick also keeps your legs within the slipstream of your body so that you punch a hole in the water that is only as big as your shoulders and your tank. Remember, less drag means more speed and less effort.

    Love this fins, though it's probably too big for my height (153cm). I need good effort to kick in water.

    Love them

    Very happy with these fins. Not as mutch power as my old hard fins....but way less fatigue and in rough nor Cal surge I can still hold my place just takes a few more kicks. These fins are worth every cent. The reason I gave 4 instead of 5 stars is I have size 15 feet so I bought the xl which fit but the spring backs are a little lose, might just be me but would like to have them a little tighter and there is no way to adjust.

    The fins had a few scuffs on them when I unpacked them. This is not a huge concern, nor did it effect my product review, just an observation.

    Took these to key west. I get cramps a lot in my Cressies and was looking for a split fin to try and cut down on the debilitating and time draining cramping while diving. Most of the fin that initially attracted me were shorter so I was unsure with the length on these which is similar to my existing fins. Based on the reviews on different sites I decided to give these a try and although we did have some drift I did notice a big difference and did not cramp up at all. I hardly noticed that they were even on when in the water and am super excited about reducing the possibility of leg cramps in the future now that I have these bad boys. They are expensive but you get what you pay for and in this case I feel the investment was well worth it. I also saved on the manufacturer advertised price so in my mind this was a win win. I would recommend these to other divers with similar leg cramping issues.

    Exactly what i wanted. Fit just right. I am a size 10, but I ordered a size 9 (5mm) booty and L fins. Everything worked perfect.

    Finally getting rid of my foot bannanas

    I've been envying my son's and daughter-in-law's fins for too long! Mine were OK, but they've warped pretty badly over the past few years and even though I've tried everything to straighten them out, it hasn't worked. The Atomic Aquatics split fins don't seem to warp even after months of storage in a flexed position and they are very efficient in terms of the amount of effort required to produce useful thrust.
