Description


The Molchanovs CORE Unisex Silicone Bifins are high-performance training fins engineered for freedivers, swimmers, and underwater sports enthusiasts of all skill levels. Crafted from premium hypoallergenic silicone, these compact bifins provide a smooth balance of flexibility, stability, and propulsion during pool workouts and open water sessions. Unlike standard stiff plastic fins that encourage improper knee bending, the flexible CORE bifins cultivate clean, symmetrical kicking mechanics for maximum energy efficiency.

Featuring dedicated right and left foot pockets with integrated arch support, these fins hold the feet in an optimal pointed position to streamline every stroke. The open-heel construction and ergonomically molded back strap fit comfortably over the Achilles tendon, enabling full ankle range of motion without sacrificing security. Eight specialized blade rails distribute structural stiffness across the surface, delivering impressive torque and thrust with minimal effort in temperatures down to -30 degrees C (-22 degrees F) .

With a compact total length of approximately 58cm (22.8in), the Molchanovs CORE Silicone Bifins are exceptionally travel-friendly and pack easily into luggage or gear bags. Due to the arched foot position, they may feel slightly short when standing but fit correctly while floating. Designed to fit true-to-size for general use or 1-2 sizes smaller for an ultra-responsive competition fit, they are an essential tool for perfecting technique, building endurance, and executing underwater maneuvers.
