Endorfine KS1 Kelly Slater Future Compatible Medium Tri-Quad Fins

Developed in collaboration with Kelly Slater, eleven-time World Surf Champion, the Endorfins KS1 5 Fin Set Medium are reference fins for surfers who demand the best from every session. Versatile, ultra-light, and with cutting-edge technology, they allow for Thruster or Quad setups, adapting to your style and the day's conditions.

Technology that makes a difference:

• Core composed of approximately 90% air — extreme lightness without losing robustness
• Carbon fiber inserts for precise flex pattern and superior response
• Float in water, making recovery easier if they detach from the board
• Construction designed to maximize energy transmission in every turn

Compatibility:

Futures Single Tab system, with screw fixation for a secure and reliable fit in all sessions.

Performance in any condition:

Acceleration, stability, and control even in the most demanding maneuvers. Whether in small waves or more powerful conditions, the KS1s adapt and respond consistently — exactly what you'd expect from fins created with Kelly Slater.

Design with identity:

The iconic circle present on each fin represents the continuous flow of water and pays homage to Kelly Slater's vision — oriented towards innovation and the future of surfing.

Environmental commitment:

The philosophy "Screw your fins, not your ocean" encourages the use of screwed fins to reduce material loss in the ocean. Through the SeaTrees initiative, Endorfins supports the preservation of kelp forests in California, rainforests in Africa, and mangroves in Indonesia, offsetting the carbon footprint of production.
