A shoe sole includes: a sole body located to extend continuously from a forefoot portion to a rearfoot portion; and a highly rigid member fixed to the sole body, the highly rigid member being formed of a material that is higher in rigidity than a material forming the sole body. The highly rigid member includes a curved plate portion extending in a direction crossing a right-left direction corresponding to a foot width direction of a foot of a wearer. The curved plate portion has an inverted arch shaped portion that protrudes toward a ground contact surface of the shoe sole in a cross section taken along a line orthogonal to a direction in which the curved plate portion extends. At least a part of the curved plate portion is disposed in the forefoot portion.
