F4 Propulsion represents the latest evolution of Military-style Fins from IST. Based on IST's iconic and military favorite F-1, the F4'swide blade design is slightly shorter however, there is no power shortage here. That s because of the expanded width rubber blade which incorporates unheard-of flexibility. Even more thrust is attained by 3 deep vents which force water backwards, emulating the effect of three synchronized turbo-powered water jets.

  • SPECIALTY DESIGN — A curved, tapered blade with an open back designed to be worn with dive booties.
  • SHORT BLADE — The same power and reliability as the original F1 Rubber Rocket in a compact style.
  • EASY WEAR — Adjustable straps and quick-release buckles make donning and doffing easy.
  • JET STYLE — Deep grooves and vented blades force water backwards for better propulsion.
  • Open Foot Pocket — Designed to ear with dive booties
