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.

Customer Reviews
Well made, comfortable and can swim all 4 strokes. Very good in strengthening ankle and moving fast in water . Very nice to use
most fins when you use them will propel you forward giving you the wrong sense of power use. Positive Drive Fins provide resistance for training and a bit of push needed. it trains how you use your legs properly. as i am injured, this helps me focus on proper kicking and help recovering. i did not have a chance to use it with all strokes yet though only on freestyle
