Slater Designs Usage
Advanced Endorfins Technology
Kelly Slater's signature Endorfins feature 1-Tab design for quick release and secure fit, delivering responsive turning, speed, and drive across wave conditions.
5-Fin Versatility
KS1 5-fin sets allow multiple configurations (thruster, quad, 2+1) – adapt to wave type, board shape, or personal preference for maximum performance.
Twin + 2 Setup
Twin + 2 fins combine twin keel stability with small side fins for added pivot and release – ideal for small to medium waves, emphasizing flow and speed.
Lightweight & Durable Materials
High-grade composites and construction provide strength without weight – fins hold flex patterns longer for consistent feel and longevity.
Premium Board Protection
S-Labs Terry Board Sock uses soft terry fabric to cushion boards during storage or travel – prevents dings, scratches, and wax transfer while keeping boards clean.
Proven by Kelly Slater
Designed and tested by the GOAT himself – fins and accessories reflect elite-level performance, innovation, and attention to detail for surfers at every level.
