IST Bora Bora Adjustable FinsThe Bora Bora Fins are a traditional favorite for scuba divers because of their powerful and durable design at a great price. The large channeling rails capture the water and force it back through the flexible center membrane, creating a massively powerful thrust with minimal effort. The word to describe this fin is efficient. The Bora Bora fins will take light easy kicks and create speed, and under heavy kicking will propel the diver mightily through any underwater condition. See the S55 or S7-30 boots for an excellent fit. Powerful. Durable. Comfortable foot pocket. Imported.
