ride number (Beta)
3/10
To help simplify things, we’ve assigned a single “ride number” to each of our fins. This number is based on a variety of factors including the fin’s flex, shape, and foil. Fins with lower ratings are stable and predictable while higher ratings are more responsive and lively. Ride Number is currently BETA, so expect more info soon....
foil
FLAT Foil
Flat foiled fins break free sooner, and are better ay controlling speed. Often surfers prefer them in fast powerful surf where they do not need to create additional speed. If you have muscle memory from riding glass-ons, flat foiled fins will feel the closest.
