Kelly Slater's Endorfins KS1 5 Fin Set
The Firewire Endorfins Slater KS1 2-Tab 5 Fin Set is Kelly Slater's signature take on Endorfins, built with a core comprised of 90% pure air.
A Better Build
Innovative carbon inlays in Endorfins add strength and flex that let the fins be built with a core of 90% pure air. The result is a set that FCS describes as providing optimum performance while literally floating on water.
- Carbon inlays add strength and flex
- Core comprised of 90% pure air
- Fins float on water
Fin Box Compatibility
This set is built with a base compatible with either two-tab or single-tab fin boxes. The Futures-compatible base works just like a fin built by Futures with a Futures base. The FCS II compatible base requires two screws that come with the fins, and unlike a standard FCS II fin, it will not click in or click out.
Who This Fin Set Is For
This 5 fin set gives you the pieces to run either a thruster or a quad configuration, so it suits surfers who like to switch their setup depending on the board and the conditions, all under Kelly Slater's own signature build.
The Eco Story Behind Endorfins
The circle on the side of each Endorfins fin represents flow, a new take on Kelly's iconic circular branding. Kelly has a hobby of collecting abandoned fins from the reef in front of his home in Hawaii, and because Endorfins are screwed in and float rather than clicked in and lost, they help prevent that kind of ocean debris. Endorfins also supports Sea Trees, offsetting its yearly carbon footprint by conserving kelp forest in California, protecting rain forest in Africa, and planting mangrove trees in Indonesia.
