Description
FINIS Positive Drive Fins (PDF)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 supplication kick style for Backstroke, Butterfly, and Freestyle. The PDF?s use an ergonomic foot pocket to comfortably place the feet in the ideal swimming position, and the heel strap to secure the fin, allowing the feet to flex more naturally. A closed-toe construction provides superior energy transfer from the leg to the foot. The PDF?s will increase leg strength, foot speed, and ankle flexibility for all four competitive swim strokes, making the fins great for training the Individual Medley event. Available in multiple sizes for a custom fit.Features and BenefitsEllipsoidal BladeGenerates correct propulsion in all kick stylesAsymmetrical DesignPromotes a natural inward supination kick cycleAdjustable Heel StrapCreates a customized fit that secures fin and allows the feet to flex more naturallyVersatile TrainingIncreases leg strength, foot speed and ankle flexibility for all four competitive swim strokes; great for training the Individual Medley eventBreaststroke CompatibleSafely build power in your breaststroke kickErgonomic FootpocketComfortably places feet in ideal swimming positionClosed ToeProvides superior energy transferAvailable in Multiple SizesLarge (Male 6.5-8) (Female 7.5-9)Medium (Male 3.5-6) (Female 4.5-7)Small (Male 1-3) (Female 2-4)X-Large (Male 8.5-10) (Female 9.5-11)X-SmallXX-Large
