The all new John John Florence Signature Futures are designed for the medium surfer (65-88Kg). The John John Florence Alpha fin has a medium flex pattern, not too stiff and not too flexy. It's the same template as his techflex construction, just with more flex. This fin has been a global best seller since the initial release a few years ago. The alpha construction and flat foil make this fin predictable, yet give a more lively feeling in softer surf compared to the Techflex version. All Alpha products are designed and manufactured exclusively in Huntington Beach, Ca USA.
