The present invention provides a sole structure of footwear which makes it possible for a user to walk in a special position such that a toe part is in a raised state, thus providing an exercise effect, and is constructed such that the inclination of the footwear can be smoothly changed forwards and backwards based on a metatarsal bone part, so that the user can naturally conduct exercise. To achieve the above purposes, the present invention comprises a main sole, which has an outline that approximately corresponds to an outline of a foot sole, a front cushion sole, which is coupled to a portion of the main sole which is ahead of the metatarsal bone part, and a rear cushion sole, which is coupled to a portion of the main sole which is behind of the metatarsal bone part.
