Who Should Ride the R4
This set is built for lighter, smaller riders, including younger or newer surfers along the South Florida coast, who want a fin that holds a line through carving turns rather than one built purely for speed or looseness.
Fitting and Caring for the R4
This set installs into a compatible fin box on the board it is used with; confirm box compatibility before ordering. Rinse the fins in fresh water after every saltwater session, since salt buildup can affect both the finish and the fit in the box over time.
The Future Fins Background
Future Fins was started in 1996 by the Longo brothers, whose earlier work involved tackling complex aerospace parts and building hydrogen fuel cells for research before they turned that technical background toward surfing.
Why Buy the R4 from Island Water Sports
