Firewire Slater Designs KS1 Thruster Medium Fin Set

Leave it to Kelly Slater to reignite the innovation spark in the fin world! The G.O.A.T. is back with a bang, bringing us the Endorfins KS1 fin—reviving the best-selling fin template of all time, but with a futuristic twist in construction.

When the original Slater KS1 fin was discontinued years ago, who would've thought it would still hold its place as one of the most progressive fin designs? Well, Kelly did, and he's brought it back with his Endorfins line. The KS1 fin keeps the classic template with a slightly smaller center fin, bringing all the joy of the past into the present, but this time with cutting-edge, eco-friendly materials.

These fins are fully compatible with Futures fin boxes, so you can just pop them in, screw them in with the single grub screw at the top of the fin box, and you're all set for an amazing ride!

Why has Kelly put so much time and effort into this? Two main goals: First, a better fin construction for more performance and response, and second, an eco-friendly approach. These fins are crafted from a Carbon Fiber Twill, combined with a non-woven carbon veil and a recycled PET core. This mix of materials creates a flex pattern that gives you plenty of hold when you push hard, without feeling too stiff, and it offers fantastic bounce-back when coming out of a fast turn.

The second part of Kelly's mission is to reduce fin loss with his screw-in design. By using recycled materials and making these fins lightweight enough to float, the goal is to keep them from falling out of your board, making them more durable and long-lasting.

In summary, Kelly Slater has nailed it once again. These fins are a true game-changer for surfers, combining performance, durability, and eco-consciousness. Get yours now—you won't be disappointed!
