IST Propulsion Rubber Fins

  • Propulsion represents a new generation of rubber fin. The fin is deliberately made slightly shorter but no power is lost through its wider blade and the utilisation of rubber’s unmatched flexibility. In fact, more thrust is gained by the 3 deep vents, which force water backwards, mimicking the effect of water jet.
  • The fin is not only useful in the ocean but also capable of handling technical dive missions in underwater confined spaces.
  • The choice of material makes Propulsion durable and long lasting IST stainless steel spring fin strap compatible (item no.: FS10)


Sizes: M (US 7-9 EUR 36-38), L (US 10-11 EUR 39-42), XL (US 11-13 EUR 43-36)

Question asked
on 4/4/2013
Description indicates this rubber fin is short but has a wide blade. Can you give me the approximate measurements of fin (back of foot pocket to blade front and width across foot pocket as well as front part of blade)? Would this fin work good for ocean dives with strong currents, or would there be an excessive amount of exertion involved due to fin being shorter? Most of my diving is done in cenotes and caves. Fin looks like it might be suitable in tight spaces and for underground river type diving; but I would sure appreciate having some imput as to how these shorter fins would perform in open water dives. Thank You!!

Hello, Got your phone message and just got the answer for you: Thank you for the email. Here are the measurements for a size large, they will slightly vary based on the size. back of the fin, from heel to blade tip: 20.5" blade (not including foot pocket): 9.75" width across foot pocket: 4.5" width across blade: 9" To answer the other questions. This fin is great for tough currents due to the vents, it will not cause excessive exertion. It is perfect for tight spaces, including cenotes and caves. They will perform great in open water dives.
