The SEAC series of Shout spearfishing and free diving fins feature a full foot, open-toe, non-vented blade that is very flexible and comfortable to wear over prolonged use. The composite design blade, made from thermoplastic technopolymer provides exceptional performance and durability. The 22-degree blade angle fits the anatomically correct natural angle of the foot and leg for optimal performance with less effort. Side rails and ribs reduce water spilling over blade edges during the kick, improving efficiency, thrust, and power. The foot pocket heel pull-tab makes it easy to slip the fin on and off. Founded in Italy in 1971, SEAC proudly continues to take the lead in producing high-quality diving gear and ensures that each and every product is individually verified and tested.
