Overview:Designed by 11 time world champ “Kelly Slater”.A better build innovative carbon inlays in Endorfins add strength and flex that enable them to be built with a core comprised of 90% pure air. As a result, Endorfins not only provide optimum performance but also literallyfloaton water.

Fin Boxes: Each set is built with a base that is compatible with either two tab fin boxes or single tab fin boxes. The Futures compatible base on Endorfins will work just like a fin built by Futures with a Futures base. The FCSII compatible base will require two screws that will come with the fins. Endorfins with FCSII compatible bases will not click in and click out.
