Firewire Endorfins Slater KS1 Fin Set that floats
The Firewire Endorfins Slater KS1 1-Tab 5 Fin Set is built around a better build, innovative carbon inlays that add strength and flex, enabling the fins to be constructed with a core comprised of 90% pure air. As a result these fins not only provide optimum performance but literally float on water, a genuine point of difference for surfers researching Endorfins fins and asking how the KS1 set actually performs.
Fin box compatibility
Each set is built with a base compatible with either two tab fin boxes or single tab fin boxes. The Futures compatible base works just like a fin built by Futures with a Futures base, while the FCSII compatible base requires two screws included with the fins, and Endorfins with FCSII compatible bases do not click in and click out like a standard FCS II fin.
Who this fin set is for
This is a five fin set built for surfers who ride a quad or thruster plus stabilizer setup and want the performance benefits of a full carbon inlay build. Because the fins float, they also suit surfers who want extra peace of mind if a fin ever comes loose during a South Florida beach break session.
Fitting and caring for your fins
Confirm which base your board uses, Futures style or FCSII style with screws, before installing this set, since the two mounting methods are not interchangeable. Rinse the fins in fresh water after every saltwater session, and if you use the FCSII compatible base, periodically check that the mounting screws remain tight.
Built by Endorfins and Kelly Slater
The circle on the side of each Endorfins fin represents flow, a new take on Kelly Slater's iconic circular branding that has appeared on every fin he has endorsed, paying homage to the past while building forward. Endorfins also ties into an eco story built around Slater's habit of collecting abandoned fins from the reef near his home, and because Endorfins float, using them helps prevent fins from becoming ocean debris. Endorfins additionally commits to offsetting the yearly carbon footprint of its fin production by conserving kelp forest in California, protecting rain forest in Africa, and planting mangrove trees in Indonesia.
