About Atomic Aquatics Full Foot Split Fins

Split fins have become the most popular style fin in diving today. Just look around when you are out beach diving or on the charter boat and you will soon discover that more divers are making the switch to this style fin. Why are they so popular? They are popular because they work, and you, work less! A split fin performs more like the combination of a whale's tail and a propeller. When you kick the two separate blades twist and create more of a propeller surface which will increase your propulsion and lift. You feel as if the fin is not strong enough to keep you moving as fast as you are accustomed with your full bladed fin, yet you cover the same distance in the same time.

Less Drag, More Thrust and most important Less Strength is Used. The Split Fin Design is not only unique; it uses the Latest Technology in Composite Plastic Polymer Materials to give a Light Fin (Great Travel Fin) and one that Increases Thrust and Reduces Fatigue. Extensive R&D and Testing yielded the perfect formula of Flexibility and Rigidity for Efficient Propulsion. Atomic Multi-Composite Plastics result in a Powerful Kick that requires Less Effort, Stress and Strain meaning Less Air Consumption. The Power Rails are Highly-Resilient and Perform as the Backbone of the Split Fin, Storing and Releasing Energy with Every Kick. The Semi-Ridged Flex Battens set in the Soft Elastomeric Blade, Control the Precise Wing Shape to Optimize Thrust and Reduce Drag. The Large Surface Area Blade Improves Pivoting, Turning and Alternate Kick Styles.

Thin, yet Strong and Highly Flexible Hinge Points between the Semi-Ridged Battens cause the Blade to React Quick-and-Efficiently to the Slightest Kick. The Anatomically Contoured Full Foot Pocket designed to Fit-your-Foot without Stress Points. Foot Pocket has a Large Heel Pull-Tab for Easy Donning and Doffing of Fins. The Atomic Full Foot Split Fins are available in US sizes 4.5-5.5, 6-7, 7.5-8.5, 9-10, 10.5-11.5 and 12-14 (EUR: 36-37, 38-39, 40-42, 42-43, 44-45 and 45-47), comes in Black or Yellow colors and is covered by a 12 month limited warranty.

Best fins EVER

I've been a certified diver since early '80's, spent 10hours/day in the water as a marine biologist in the early 90's, and currently dive both recreationally and as a certified Police Diver. And I don't think I have EVER been comfortable in any set of fins, either open healed or footies, until I put on these... These are hands down the most comfortable, easy wearing fins I've ever had. I recently battled blisters with my old fins, and based on the review here purchased these fins, along wit...

These fins Give Me Superpowers


from Atlanta, GA, US

These fins are incredible. I researched for months before choosing. I place comfort at the top of my priority list, followed by efficiency and ease of use in the water. I am a 5'11' average slim build woman with 9.5 women's shoe size. I bought the Atomic Aquatics Full Fot Split Fin in 7.5-8.5. They fit like a glove in and out of the water. Performance: increased thrust, reduced fatigue, lightweight, great for travel, accomodating to differnt kick styles. To ensure comfort in a fin, you have to make sure no hard parts of the fin press against your foot when you move in the water. They should also be snug out of the water, as they will never become more tight once you get wet. These have an open tow which adds superior comfort (and you don't have to pour water out). Full foot is best for snorkeling and swimming around in water where you'll otherwise be barefoot. (open backs are for use with bootie shoes and full dive gear). I purchased these to take on my snorkeling trips. I like to stay on the ocean for hours at a time, every day for a week, spending multiple hours snorkeling. I want to be able to maneuver and be safe with the coral. Also I can stick these in my stand up paddleboard backpack and keep it moving! Blade fin vs. split fin. Blade fins are more popular because people think they are kicking harder and getitng more thrust, but they are fatiguing the legs faster. Split fins give more endurance, and decreased fatigue and move you through the water like lightening - when you use the recommended flutter kicking style (just kick your feet up and down like normal, with a smaller range of motion, staying within your body frame, moving from your hip, not your knee. You can go to the Atomics website to research howand why these fins work the way they do. Yes - you can get a decent pair of fins for $35-40. But I decided to splurge on the best in the world - Edward Norton, Kevin Costner, David Blane, and Antarctic science explorers all use Atomic Aquatics. It pays to go with the best for superior comfort and durability and performance. My two cents. :-) I bought them in bright yellow. Some people argue fish may be attracted to bright colors, or that you can't hide from the fish, there are multiple debates. For me, it's most important to be seen by a boat and not get run over more easily than with black.


Great Performance - Poor Lifespan


from redmond, WA, US

I really liked the performance of these fins. They worked great for warm water diving vacations but they came apart at the seams after about 100 dives. I wore these barefoot but found that after diving 2 tanks/day for a couple of weeks, my ankles and feet would get rubbed raw and so I started wearing lycra sock when using these fins. Even so, when I shop for new fins, I will consider buying these fins again.


Excellent full foot split fin and spot on fit


from Morristown, TN, US

I purchased two pairs of these (for my wife and I) as we are getting older (and my knees give me problems sometimes). My wife used them solely for snorkeling (and very little of that) and I used them mostly for scuba diving (13 dives over 5 days) in warm St. Croix waters while on vacation. I tend to wear between size 10-11 shoes (depending on brand), usually 10.5 or 11. I bought the 10.5-11.5 sized fins and they fit perfectly. My wife has tiny feet and ideally wears woman's size 5.5 (sometimes size 5 and sometimes 6 if she can't find anything smaller, which is a problem these days). The sized 4.5-5.5 fins I got her fit her perfectly as well, although as she ended up not doing much snorkeling, I can't say much about fit beyond a one time use. That said, after about 20 hours in the water with them (between 9 dives over 4 days, plus snorkeling and a lot of pool swimming daily with them to practice various kick techniques), I noticed I did start having some skin being rubbed off my middle toes on each foot. Although I firmly believe it was not a fit issue or an issue with the brand/model of fins... I had no issues until near the end of my 2 week stay. I suspect that full foot fins on bare feet might be better for less frequent use. I might go with open heel fins (with spring straps) next time and wear dive boots to minimize chafing when doing a lot of dives back to back. Others may not have the same issue, and now that I know which toes have issues, I could preemptively wrap them with fabric Band-Aids (since they stay on in water well... several days as I discovered). I would recommend these for anyone shopping for full foot split fins, but might suggest open heel fins with dive boots for heavier users.


Well worth it!


First set of split fins I have used and I was very impressed. A few inches longer than my other fins and felt a bit clumsy out of the water but good thrust vs. effort. Worth the $.


Nice warm water fins


I wear a size 13 shoe and the XL fit just right. If you are a size 12, the pocket would be a little loose and a 14 a little snug, but probably still comfortable. The fins have plenty of power for diving with a light easy flutter kick. More power is available and would give you as much as most paddle fins. There is a difference between the materials and comfort between Atomics and Tusa fins. The Tusa's are almost as good and far cheaper, but you get what you pay for. The narrower design of the Atomics and different materials give slightly more thrust per amount of energy put in and do not tend to hit each other. I find I have to consciously keep the Tusa's apart since they have a wider design. The Atomics work better with a frog kick, but not as good as a typical paddle fin. On the surface, the 20 degree angle of the fins make a face down surface swim slightly more work than a fin without the 20 degree angle, but for diving this is a plus for the typical body position during scuba diving. Nice fins. The only reason for 4 not a 5 is the surface swimming is not perfect.
