FINIS Positive Drive Fins use a unique ellipsoidal blade to generate correct propulsion in all four swim strokes. In addition, the asymmetrical blade design also allows the swimmer to build power while promoting a natural inward supination kick style for butterfly, backstroke as well as freestyle. FINIS Positive Drive Fins use an ergonomic foot pocket to comfortably place feet in an ideal swimming position. Moreover, the heel strap secures the fin, allowing feet to flex more naturally. Furthermore, a closed toe design also provides superior energy transfer from leg to foot. This drive fins will increase leg strength, foot speed as well as ankle flexibility for all four swim strokes, making the fins great for individual medley training.
