A sole system for an article of footwear can include a sole member and a protruding member assembly. The sole member includes outwardly and inwardly facing surfaces, a plurality of spaced apart first apertures extending though the sole member, and a plurality of first protruding members extending outward from and fixed to a base surface of the outwardly facing surface. The protruding member assembly includes a plurality of second protruding members that are interconnected by connecting portions, where the connecting portions are received on the inwardly facing surface of the sole member, and where each second protruding member is vertically movable within a corresponding first aperture of the sole member.

A sole includes a support sheet and a sole body divided into a rearfoot portion, a forefoot portion and an arch portion. A hardness of the support sheet is higher than that of the sole body. The support sheet comprises a main body and an extension portion, a thickness of the main body is greater than that of the extension portion, a side of the main body is flush with a side of the extension portion. The sole body comprises an upper surface, a lower surface, and a through hole penetrating the upper and the lower surfaces. The through hole in the arch portion receives the main body, the side of the main body faces away from the lower surface. A recess is recessed from the upper surface at least corresponding to the arch portion towards the lower surface, the recess communicating with the through hole receives the extension portion.

A shoe sole with a guide element which is embedded between a ground contact surface and a foot contact surface of the shoe sole, is designed to control the optimum movement sequence of the foot, has a smaller width extension than the shoe sole and extends along an S-shaped line, in such a way that the shoe sole further supports the natural or correct gait of the user, it is proposed that the guide element is a proprioceptive guide element and has elevations extending towards the foot contact surface, and/or that the shoe sole has, in the heel section arranged medially to the substantially S-shaped line, a stabilization element which can be detachably fastened in the shoe sole and which extends out of the shoe sole in the direction of and up to the plane of the ground contact surface.

A component for a shoe, intended to be interposed between a foot and the ground, is delimited by an upper surface which, in use, is turned towards the foot. The upper surface comprises a load-bearing region in which at least one recess is made, the recess being configured to receive at least one metatarsal head of the foot, so that in the load-bearing region a plurality of metatarsal support levels is defined, the metatarsal support levels being placed at different heights from one another and being intended to support the metatarsal heads of the foot. The plurality of metatarsal support levels comprises, in the more simplified embodiment, two different metatarsal support levels. In a more complex embodiment, three different metatarsal support levels are provided. In a more complete embodiment, five different metatarsal support levels are provided.
