Description
K4 fins have created a unique and new material for windsurfing. OptoFlex is a molded resin long fibre matrix that has been carefully manipulated to provide the perfect flex patterns for windsurfing. Our K4 technicians took a long time to create the perfect material with the qualities needed to provide the performance we now appreciate. Lighter, snappier and with outstanding flex memory. The fins are extremely robust too -we haven't had a single return through breakage.
The Ezzy Assymetric 3 degree US or Slot Box
The Ezzy Asymmetric fin! More power, more drive, more speed, less drag. This fin has a similer template to the Stubby but with an even wider base. Fully asymmetric foil with a radiused front and slightly positive inner foil to aid flow at high speeds. Choose a smaller fin size for less drag, same power. Great for huge gouging hooky cut backs.
Easy conversion to make US box into Slot Box
