These fins move with the water to give you a more fluid shred. Pretty nifty, huh? These flex-fold fins allow surfers to ride like they never have before. "This cutting edge technology will help intermediate surfers master maneuvers they thought they could never do and as for elite surfers the possibilities are endless," the Team Slide Fins website. "It is only a matter of time before we see many surfers performing 720’s and 1080’s achieved in one continuous sliding maneuver, with the help of Slide Fins." Maybe we should try putting a few on a Slyde Handboard. We'd be in for a pretty slippery ride!
