Finis Positive Drive Fins

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 supination kick style for Backstroke, Butterfly, and Freestyle.

The foot pocket keeps the feet in the ideal swimming position. The closed-toe design helps to transfer the energy from the leg to the foot. The fins will increase your leg strength, foot speed, and ankle flexibility for all four competitive swim strokes, making the fins great for training the Individual Medley event.

Positive Drive Fins Feature:
  • Ellipsoidal blade that creates the correct propulsion in all kick styles.
  • The asymmetrical design encourages a natural inward supination kick cycle.
  • Adjustable heel strap that provides a secure fit and allows the feet to flex more naturally.
  • Great for all four swim strokes including the breaststroke.
  • closed-toe, ergonomic foot pocket for an ideal swimming position.

Fast delivery and awesome product.

I Bought a pair of these positive drive fins. They are much better than other fins, even the new zoomers. These fins allows the swimmer to develop better ankle flexibility with time because of their strap design around the heel. SunPlay has the best prices and quick delivery.

Great Versatile Training Fin

Bottom Line Up Front-
An appropriate swim training aid for all swimmers who desire to improve swimming technique. This is not a recreational swimmer's fin.

Pros:
Versatile
Requires proper technique
Comfortable foot cup

Cons:
Strap adjustments take a while
Fits smaller than recommended sizes

Detailed Review
Fins have a stigma of being misunderstood as a way a swimmer swims faster with less energy expended. Fins do have a purpose as a training aid by strengthening leg muscle, improving aerobic capacity, and teaching proper technique. Positive Drive Fins (PDF) by Finis delivers on all these fronts.

Initially, I was a non believer and thought it more of a gimmick. The biggest question I had for these fins was whether or not the 'all in one' solution was really true. To test this out, I compared the fins with a breaststroke specific blade fin and Zoomers to see if the same training benefits could be achieved. The only negative difference I found was that breaststroke specific fin forced a classical breaststroke kick more than the PDFs. However, there are many positives. PDF unique shape allows swimmers to use a natural and powerful inward kick without interference that kicking with Zoomers sometimes cause. Like Zoomers, the short blades must be driven rapidly improving kicking technique and increasing strength. Zoomers cannot be used to kick breaststroke.

From a technique perspective, I wanted to see if a lay swimmer could improve form by kicking with these fins. I found a recreational swimmer with significant knee bend and offered the fins to try. She had to reduce the knee bend and utilize proper form to drive the fins and go forward at the speed she desired. Swimming with the fins, her freestyle technique improved drastically without the deep knee bends. She asked me where I purchased the fins.

I have found that the PDFs meet my criteria for swim training with fins. I will be sharing them with my local swim team as another tool to improve age group to senior ...
