Abstract: The present invention is retractable finned footwear comprising an outsole with retractable fins and a lever used to extend and retract the fins. One end of the fins is rotatably connected at back end of the outsole using fastener, while the other end is extended outside from front side of outsole. The fins can be secured at the bottom of the outsole, to facilitate the footwear suitable for walking on land. The fins can be extended from bottom of outsole by pulling the lever positioned at the back end of the outsole. The extended fins provide forward propulsive thrust to user wearing the footwear in water. After using in water, the lever can be pushed to align and secure the fins in line with the outsole. This facilitates the use of footwear both in water and land.
