The Positive Drive Fins (PDF’s) use a unique ellipsoidal blade to generate correct propulsion in all four swim strokes. The asymmetrical blade design allows the swimmer to build power while promoting a natural inward supination kick style for butterfly, backstroke and freestyle.
The PDF’s use an ergonomic foot pocket to comfortably place feet in an ideal swimming position. The heel strap secures the fin, allowing feet to flex more naturally. A closed toe design provides superior energy transfer from leg to foot. The PDF’s will increase leg strength, foot speed and ankle flexibility for all four swim strokes, making the fins great for individual medley training.
FAQs
IS THERE A RIGHT AND A LEFT TO THIS FIN?
The Positive Drive Fin is molded as a single fin. Both fins in the box are identical, so while technically there is no right or left fin, there is a correct way to wear the fins. The fins should be oriented with the wider portion of the blade on the outer portion of your foot. On your right foot you will see the FINIS logo, on the left you will see the fin size imprinted on the blade of the fin.
