Neptonics Replacement Fin Rails
Neptonic fin rails increase the performance of your fins by channeling water down the blade while also extending the lifetime of your fins.
Sold by the kit, Neptonics rails contain two sets of 15” channels (for the tip end of the blade) and two sets of 13” low profile rails (for the foot pocket end of the blade).
They're designed long enough to fit any blade on the market. Simply cut down to size.
