The FINIS Positive Drive Fins use an ellipsoidal blade and asymmetrical design to produce efficient propulsion across all four competitive swim strokes. The short, wide blade promotes an inward supination kick for backstroke, butterfly and freestyle, while the adjustable heel strap and ergonomic footpocket let the feet flex more freely and sit in the ideal position for power transfer. Closed-toe construction delivers superior energy transfer from leg to foot, and the fins are designed to safely build power in the breaststroke kick. Benefits include increased leg strength, improved foot speed and greater ankle flexibility, making these fins ideal for individual medley and stroke-specific training. This listing is for Size XL in yellow.
