Description of Finis Positive Drive Fins Sizes Xtra Small and Small.
The Positive Drive Fins (PDF's) use a unique ellipsoidal blade to generate correct propulsion in all swim strokes. Traditionally fins are not made for Breaststroke, but the asymmetrical shape and adjustable heel strap allows the swimmer to safely build power in the Breaststroke kick. The short and wide blade design also promotes a natural inward supination kick style for Backstroke, Butterfly, and Freestyle.
The only fin for all four strokes, the Positive Drive Fins are designed for the breaststroke, freestyle, backstroke, and butterfly. They have an adjustable heel strap and are available in multiple sizes: Youth 8 to Men 13.
