About Finis Positive Drive Swim Fins, Yellow/Black

Finis Positive Drive Swim Fins, Yellow/Black
The Finis Positive Drive Swim Fins, Yellow/Black design use a unique ellipsoidal blade to achieve the correct propulsion in all swim strokes. Fins are usually not made for breaststroke, but in this case, the asymmetrical shape and adjustable heel strap of the PDF s, allows the swimmer to safely build power in the breaststroke kick. The distinctive short and wide blade design boosts a natural inward supination kick style for backstroke, butterfly, and freestyle. The Finis Positive Drive Swim Fins, Yellow/Black uses a stylized ergonomic foot pocket to comfortably place the feet in the optimal swimming position. And to secure the fin to the right fit, the heel strap is adjustable, allowing the feet to flex more naturally with a closed-toe construction providing a superior energy transfer from the leg to the foot. The PDF's are great for all four competitive swim strokes, making these a good choice for training.

Questions about this item:

Michael C  That is difficult to say. Each fin is sized a little differently. and if you have very wide feet, you may just need a larger size to get the width. The best way for you is probably to try on a few different fins and sizes to see which ones are most comfortable for you, and fit best.
Michael C  I'm a men's size 11. What size would I wear? Thanks!
Marilyn S  These are great swim fins for all kinds of swim strokes. You would need an XXL. The size chart is here:
