Open Heel HEC SplitFins with Spring Straps
US$279.95
Designed for divers who demand performance and precision, the Atomic Aquatics High Energy Compound (HEC) Open Heel SplitFin pair a high-performance compound with the trusted Atomic Aquatics Spring Strap Assembly—delivering unmatched comfort, control, and buoyancy.
Spring Strap Synergy
The integrated Atomic Aquatics Spring Strap Assembly ensures a secure, adaptive fit that moves with your foot. This system allows for quick donning and doffing, while maintaining optimal positioning throughout your dive. When paired with the fin’s buoyant compound, the spring strap enhances hydrodynamics and eliminates unnecessary drag—making every kick count.
High Energy Compound Advantage
Crafted from a lightweight, high-energy compound (HEC), the HEC SplitFins remain neutrally buoyant in both fresh and salt water. Unlike standard compounds that sink and strain your kick cycle, this advanced formulation boosts thrust and reduces fatigue. Originally developed for elite divers, this compound is now featured in Atomic Aquatics’ boldest fin design.
Performance Meets Style
Whether you’re navigating coral reefs or gliding through kelp forests, the HEC SplitFins deliver high thrust with low frequency kick cycles, making them ideal for long dives and strong currents. The sleek design and premium materials reflect Atomic Aquatics’ commitment to innovation and underwater excellence.
Engineered for divers who demand precision, comfort, and performance, the Atomic Aquatics HEC SplitFins combine a buoyant, high-performance material with the trusted Atomic Aquatics Spring Strap Assembly—delivering unmatched control and effortless propulsion.

SplitFin Performance
The split blade design of the HEC SplitFins delivers high thrust with low frequency kick cycles, making them ideal for long dives and strong currents. The split fin channels water efficiently, reducing resistance and enhancing speed with less effort—perfect for divers who value both power and endurance.
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.
- Spring Strap System Adaptive stainless-steel spring strap provides a secure, custom-fit comfort that automatically adjusts to depth and movement. Its streamlined profile enhances hydrodynamics and virtually eliminates drag.
- HEC Compound Precision-engineered High Energy Compound delivers slight positive buoyancy in both salt and fresh water. Designed to reduce diver fatigue while maximizing thrust efficiency with every kick.
How Atomic Aquatics SplitFins Work
SplitFin Wings “Slice” Through the Water
Traditional paddle fins work by pushing water rearward. As a paddle fin is pushed through the water, much of the water spills over the top surface of the blade and sticks to it, creating drag. Extra kicking effort is required to overcome that drag. The Atomic Aquatics SplitFin slices through the water with two wing-shaped surfaces, creating lift and forward propulsion more like a propeller. Any water traveling over the top of the blade is funneled into and out of the opening (split) between the wings. Drag is reduced, effort is reduced, and efficiency is increased.
Propeller-Fin™ Technology Moves You Faster
Atomic Aquatics SplitFins use Propeller-Fin Technology to deliver ultra-high speeds with a small-range rapid flutter kick. This works in the same manner that increasing the RPM on a boat propeller accelerates a boat to high speeds.
Multi-Composite Plastics And Other Uniquely Atomic Aquatics Features
The Atomic Aquatics signature is our use of exotic materials specifically designed to improve performance. We developed multi-composite plastics for the SplitFins to maximize the efficiency of the kick with less fatigue. Flexible side rails and a stiff foot pocket are combined with stiff battens in the blade to control the flex pattern for optimum performance. Our patented EZ-LOK Buckle System is one of those distinct Atomic Aquatics features that make divers love us even more.
