1. A sole structure of a sole of a shoe, comprising:
a rearfoot-side concave-shaped portion including a vertex region in a bottom surface of the sole in a rearfoot region,
the vertex region including a substantially flat surface in a longitudinal direction and an upward convex curvilinear shape in a width direction at a highest position within the bottom surface of the sole in the rearfoot region and configured to be positioned at a position corresponding to a center of a heel of a wearer such that center of pressure of the wearer overlaps with the center of the heel; and
a continuous ridge surrounding the rearfoot-side concave-shaped portion and projecting downwardly to create a crater shape around the rearfoot-side concave-shaped portion, the continuous ridge formed by a pair of rearfoot ridges, a boundary ridge and a rear end ridge, the pair of rearfoot ridges disposed on opposite sides of the vertex region in a width direction, the boundary ridge disposed at a boundary between a midfoot region and the rearfoot region on a front longitudinal side of the vertex region, and the rear end ridge disposed on a rear longitudinal side of the vertex region.
