This set of Twin Keel Fins is compatible with Futures Fin boxes (the type of boxes we use on all of our shortboards). This Twin is more upright and with less surface area, leading to a more responsive feel underfoot. This means they will work best in our streamline twin models such as the Sandia Fish, WTRP, and the Beach Chicken.
