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.
