Description
Atomic Aquatics Open Heel Fin employs Propeller-Fin technology with a flexible split blade to reduce drag and increase forward propulsion. With the slightest kick, the blade deflects to form wings that slice through water more efficiently, helping scuba gear and diving sessions feel smoother and more comfortable underwater.
Designed for open-heel setups, these fins pair with standard dive boots and deliver efficient propulsion with less effort for scuba and diving applications. Independent testing indicates the split blade can reduce air consumption while maintaining speed, power, and comfort across divers in underwater environments.
Features
Features
- Power Rails: The highly resilient power rails perform as the backbone of the splitfin, storing and releasing energy with every kick. Proprietary and exclusive to Atomic Aquatics, this material will not deteriorate or lose its resiliency.
- Flex Pattens: Semi-rigid battens set in the soft elastomeric blade controls the precise wing shape to optimize thrust and reduce drag.
- Split Blade: The split blade deflects with the slightest kick to form a pair of wings that slice through the water with reduced drag, propelling you forward.
- High Surface Ratio Blade: Large surface area blade improved pivoting, turning and alternate kicking styles.
- Hinge Points: Thin, yet strong and highly flexible hinge points between the semi-rigid battens cause the blade to react quickly and efficiently to the slightest kick.
- Anatomically Correct Foot Pocket: Contoured to fit your foot without stress points, with semi-open toe for added comfort.
- Power Plate: Internal sole plate creates rigid platform beneath the foot for greater power transfer to the blade yet allows soft, comfortable foot pocket.
- EZ-LOK Buckle System: Totally new, patented buckle system design features easy, one-handed quick release of the buckle from the fin. Re-attachment is simple and secure. U.S. Patent #6,463,640.

Even with the slightest kick, the split blade deflects to form a pair of wings that slice through the water with reduced drag, creating lift in the forward direction to propel you ahead. Compared to conventional fins, the Atomic SplitFin® swims with less effort, stress and strain resulting in greater sustained speed, power and com-fort. Independent testing has shown that this design can significantly reduce air consumption

Frequently Asked Questions
What is the difference between open-heel and full-foot fins?
Open-heel fins have an adjustable heel strap and are worn with dive boots, which protect your feet on shore entries and add warmth. Full-foot fins slip on like a shoe against bare skin or a thin sock, and are typically lighter and easier to pack. Most scuba divers choose open-heel fins with boots, while full-foot fins suit warm water, snorkeling, and pool use.
How should scuba fins fit?
Open-heel fins should be sized around the boots you will actually wear, snug with the strap set so your heel stays seated and your foot does not slide forward in the pocket. Full-foot fins should fit like a firm shoe, with no heel lift, no pinched toes, and no gap that lets water pump in and out. Too loose causes heel blisters and lost fins in current, and too tight causes foot cramps.
Should I buy dive boots before fins?
Choose your boots first and size open-heel fins around them, because sole thickness changes the foot-pocket size you need. A thin warm-water boot and a thick cold-water boot with a rugged sole can easily be a fin size apart. If you already own fins, bring them along when you buy boots so you can check the combination.
Are spring straps worth it?
Spring straps replace the adjustable rubber strap with a stainless spring that stretches on and off, so there is nothing to buckle with cold or gloved hands and no rubber strap to perish and snap mid-dive. They hold constant tension, which many divers find more comfortable and consistent. They are sized rather than adjustable, so match the length to your foot pocket and the boots you dive.
What are the best fins for travel?
For travel, length and weight matter most, so shorter blades and travel-specific open-heel or full-foot models pack more easily and save baggage allowance. Some fins have removable blades or compact foot pockets designed for luggage. Pack fins along the outside walls of your bag, where they also act as protection for softer gear.
What is the difference between paddle and split fins?
Paddle fins use a solid blade that transfers power directly, which many divers prefer for precision, control in current, and non-flutter kicks such as the frog kick. Split fins have a slit down the blade that lets water pass through, which generally makes flutter kicking easier on the legs but gives up some control and works less well with other kick styles. Neither is inherently better, so let your kick style, leg strength, and conditions decide, and try both if you get the chance.
How do I care for dive fins?
Rinse them in fresh water after each dive day, paying attention to buckles, springs, and strap channels where salt collects, and dry them out of direct sunlight. Store them flat or hanging from the foot pocket rather than standing on the blade tips, which can take a permanent bend. Check straps, buckles, and any screws before every trip, since a failed buckle is the most common fin problem.
