Seac L-30 Closed Heel Freediving Fins
Built for freedivers and spearfishers seeking powerful propulsion and smooth efficiency in the water, the Seac L-30 Closed Heel Freediving Fins - Blue are designed to maximise performance during long dives and surface swims. The long blade is constructed from a specialised high-performance technopolymer compound that combines lightness with excellent elastic response, delivering strong and reactive thrust with every kick. A 30° angle between the foot pocket and blade supports the natural position of the ankle, helping reduce fatigue while improving propulsion efficiency. Paired with a next-generation soft foot pocket without side rails, these fins allow the blade to flex naturally while maintaining exceptional comfort, even when worn without neoprene socks.
