Product Details

Bestselling fins designed by world-renowned shaper Mayhem!

I purchased these new, but I'm selling them because I only have Futures fin compatible boards now.
I took them out of the box to check them, but they haven't even been test-fitted!

I previously used the M size of this same model, and they performed well even in small waves.

With surf gear prices trending upwards year after year, how about getting these at a great price?

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
