A universal foot fin is disclosed for use with float tubes and pontoon boats which can be selectively adapted to propel either forward or backward in the water, while simultaneously allowing the user to walk forward in either adaptation without removing the fin assembly. The fin assembly is described as being either (in simplest form) a separate FIN member to be attached to mounting fixtures which can be permanently affixed to or molded integral on wading boots, or as a complete assembly including a base member to be secured to wading boots by an releasable binding mechanism In use the fin member pivotally retracts in an upward position for walking.
