A running shoe stores the shock during landing as energy and releases the stored energy when kicking off the toe portion, thereby making running and walking more efficient. The running shoe includes a shoe main body 10 into which the foot is inserted and a plate spring 5 that is large enough to cover an entire length of the shoe main body 10, is attached to a lower portion of the shoe main body 10, and is closed at a heel end portion thereof. The plate spring 5 is attached to a lower surface of the shoe main body 10 at only a toe end-side of the shoe main body 10.
