K4 Shark Slot Box Paddleboard, SUP, Windsurfing Fins

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

Sold as a pair but if you would like a single for £11.25  just ask.
