Injection molding process ensures geometric accuracy and provides a reliable and consistent feel. These fins are ideal for novice surfers because the relaxed (subtle) flex of these fins can be engaged with minimal effort, and as the flex returns to a neutral position the fin produces a whip-like effect that propels the board forward, and helps to maintain speed and acceleration
