Endorfins Slater KS1 FCS II Tri Surfboard Fins - Medium/Black

Slater KS1 medium size tri-fin FCS II surfboard fins by Endorfins. Designed by 11 time world champion surfer 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 literally float on water. -FIN BOXES: 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. 

- THE ECO STORY: ‘Screw your fins, not your ocean”. Kelly has a hobby of collecting fins from the reef in front of his home in Hawaii. These fins are trash, abandoned on the ocean floor. By screwing our fins into our surfboards – and with the fact that they float - we prevent this from happening.
