The Bolero asymmetrical surfboard set combines our best selling quad and twin fin shapes into one unique asym fin bundle. The fins are compatible with standard Futures fin boxes and are made from solid fibreglass for longevity, built to last. Our asymmetrical fin set up is designed to be surfed with the twin fins under the toes of the surfer and quad fins under the heel. The twin fin provides speed, drive and freeness when pushing off of the toe side rail and the quad fins provide additional hold under on the heel side rail. Due to natural body dynamics, a surfer generally tends to push harder off their heels, perhaps in a forehand carve or a backhand bottom turn. Accounting for this imbalance with an asymmetrical fin set up can create an exciting new experience, achieving the best of both worlds.
