Designed by 11 time world champ "Kelly Slater" KS1 — Large FRONT CENTER B — 116mm B —111.5mm H — 119mm H — 115mm 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: 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. THE BRANDING: The circle on the side of each Endorfins fin represents flow. It's a new take on Kelly’s iconic circular branding that has appeared on every fin he's endorsed previously, paying homage to the past while building forward towards the future. 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. We are additionally continuing our commitment to Sea Trees – ‘wiping’ the yearly carbon footprint of our fin production through conserving kelp forest in California, protecting rain forest in Africa, and planting mangrove trees in Indonesia.
