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.

• 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.
