The Freestyle fin developed with up and coming freestyler Nic Hibdige. This is a fin for modern freestyle, plenty of lift, pop and release to spring you into the next spin! Whereas K4's Bubble freestyle fin was designed for grip and control in all conditions, the ZBD is about maximizing lift and speed, ideal for flatter water. It has been described as having more pop than any of the current freestyle fins on the market!
