Zoggs 4-Stroke Positive Drive Fins provide exceptional performance for unprecedented results. Positive Stroke Drive Fins are uniquely designed for all four competitive stokes. The Fin Blade specifically designed to provide Superior Propulsion and Power with Off-Set Foot Pockets that Transfer Natural Foot Power into Positive Drive.
