A "Click-N-Go", no screw needed version of our Flex fin. This flexible, nearly indestructible 9" long 'touring' fin tracks straight and features a tapered shape that sheds underwater weeds and sea grass that can get caught on other fins. Flex fins bend out of the way if they encounter underwater objects, and are also a great safety feature. Click-Fin use recommended for all ISLE inflatable boards - hard boards will require use of the fin screw to ensure a good connection.
