FINIS PDF: Positive Drive Fins Perfect For Every Stroke
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 PDF’s use an ergonomic footpocket 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.

Leatherback Turtles
Yippie…! I am out of the egg Mom laid in the sand nest. You can call me a hatchling and this evening I shall crawl back to that vast ocean to meet my family.
Who am I? Well, I am Dermochelys coriacea, whom you fondly call leatherback turtle or simply leatherbacks! According to the Taxonomists I am under the Kingdom – Animalia, Phylum – Chordata, Class – Sauropsida, Order – Testudines, Suborder – Cryptodira, Family – Dermochelyidae, Genus – Dermochelys and Species – coriacea.
We are Cosmopolitan and genetically have three distinct lineages of population. You may find us in Atlantic, Pacific, Indian oceans and even in Arctic Circle too!
I am small now but will be about 6 -8 feet long one day weighing 250 to 750 kg. Believe me or not, one of my ancestors was 916 kg. Atta heavy-weight guy he was!
We have a number of special characters! Firstly, we are the largest sea turtles and fourth largest reptilian….(Ooops)! Secondly, we are great swimmers and can cross Pacific and Atlantic oceans at a speed of 35.28 kilometers per hour. My mighty elders made records in swimming 20,000 kilometers in about 647 days. Some of my relations dived as deep as 1,230 meters under the sea! Courageous, I must say! One day I’ll also be a deep sea diver like them. You think I am exaggerating? Feel free to check the records!
I am called leatherback turtle because my carapace is leathery. It has 7 ridges posterior to anterior. I have two pairs of flippers of which the two frontal ones are for swimming. My beaks are very hard and pointed. The upper surface of my dorsoventrally flat body is dark grey while the ventral surface is lightly hued.
We maintain body temperature at about 180C higher than the surrounding water because of the blood supply to our bones and cartilages and the stored oxygen in the blood and tissues(other animals store it in the lungs)! Hence we can stay in cold water. Brrrr..r..r..r…!
We all relish jellyfish and squids (mmm…yummy…), but never say ‘no’ to sea snails, crabs, slugs etc.
But I am scared because of all the predators. You, the human beings also steal our eggs or kill us ruthlessly while fishing. We are already declared as critically endangered species by IUCN. Chemicals, oil spillage, plastic (which resembles jellyfish)…all these are killing us everyday.
Save us, I implore! Live and let us live too…!
