PROBLEM TO BE SOLVED: To provide a walking-enable fin with which a user wearing the fins can walk in a feeling by apparently wearing shoes when walking along a beach or ascending a ladder after finishing diving. SOLUTION: The foot bottom surface of a main body in the fin is bulged to house a spring for energizing a blade to a folding position. Thus, the thickness of the bottom of the main body can be reduced as much as possible even while housing an axis and the spring. COPYRIGHT: (C)2005,JPO&NCIPI
