Futures Fins Mikey February Fiberglass Keel Fin Set Red-GreyThe Mikey February signature keel fin is designed to enhance performance on fish style boards. We preserved the traditional characteristics of a keel fin, such as hold and down the line drive, all while adding a looser, more responsive feel when the board is put on rail. We maintained the base length, area, and tip rake to retain the keels essence, but reduced the area through the center of the fin to increase responsiveness, just as Mikey envisioned.
