Cool Factor: Highly motivated, this self-starter is easy to move at the beginning of the kick cycle.

Key Features: These all-around blades from Tusa reduce the effort required to begin each kick by angling the foot pocket 20 degrees for greater kicking efficiency. Then, to keep up the momentum, the SF-6 stays rigid on the outer edges while flexing progressively more toward the center of the fin. The result is a fin that delivers power when needed but is well suited to a wide range of divers and conditions.
