Wave Type
Kelly Slater's twin fin set, designed for a performance twin shape.

The twin fins take cues from an upright twin performance template, and come packaged with two separate trailer options, resulting in three different riding configurations.

Frequently Asked Questions
Which fin boxes are these compatible with?
Please check the product title and specifications — Firewire and Slater Designs fins are available in FCS, FCS II, and Futures configurations. Make sure your board's fin boxes match the fin system.
How do I install these fins?
Insert the fin tab into the fin box and tighten the set screw finger-tight. Use the fin key provided or a standard fin key. Do not overtighten, as this can damage the fin box.
Can I use these fins in all wave conditions?
These fins are designed for performance surfing across a range of conditions. Larger fin templates provide more drive and hold in bigger, more powerful waves, while smaller templates offer increased speed and release in smaller surf.
Care & Maintenance
Rinse fins with fresh water after each session. Store in a protective fin sock or case to avoid scratching. Inspect fins for cracks or chips before each session. Do not overtighten fin screws — finger-tight is sufficient.
