Abstract: A dual function outsole structure for use on level and sloping ground is disclosed. The outsole structure is provided with a recess for the mounting of a base plate with a rotation seat. The base plate is hidden within the outsole and the rotation seat is pivotally mounted to the two corresponding securing plates on the base plate. The rotation seat is provided with a plurality of shoe spikes and the two lateral sides of the rotation seat are provided with an elastically trigger anti-return bolt. Under normal situation one end of the anti-return bolt engages with a positioning hole provided on the securing plate such that the rotation seat is positioned. In view of the above components, under normal situation the shoe spike is hidden at the recess of the outsole and is suitable for waling on a level ground (such as on a tar road, pavement road surface or a cement road).
