1. A shoe sole comprising a rubber-made outsole, and a resin-made midsole, wherein:
- a forefoot portion of the outsole includes a medial portion, a lateral portion, and a central portion between the medial portion and the lateral portion;
a plurality of rubber-made medial cleats projecting from a base surface of the outsole or the midsole are provided in the medial portion of the forefoot portion;
a plurality of rubber-made lateral cleats projecting from the base surface of the outsole or the midsole are provided in the lateral portion of the forefoot portion;
the medial cleats and the lateral cleats are spaced apart from each other in a width direction perpendicular to a longitudinal axis of the outsole;
the medial cleats each include a first engaging surface, and a first opposing surface on an opposite side from the first engaging surface;
the lateral cleats each include a second engaging surface, and a second opposing surface on an opposite side from the second engaging surface;
the first engaging surface satisfies at least one of requirements (a1) to (c1) below with respect to the first opposing surface;
(a1) a length of the first engaging surface in the width direction is greater than a length of the first opposing surface in the width direction;
(b1) an angle of the first engaging surface with respect to the base surface is closer to 90°
than an angle of the first opposing surface with respect respect to the base surface(c1) a projection length by which each of the medial cleats projects in the width direction from an outer peripheral edge of the base surface is greater in the first engaging surface than in the first opposing surface; and
the second engaging surface satisfies at least one of requirements (a2) to (c2) below with respect to the second opposing surface;
(a2) a length of the second engaging surface in the width direction is greater than a length of the second opposing surface in the width direction;
(b2) an angle of the second engaging surface with respect to the base surface is closer to 90°
than an angle of the second opposing surface with respect to the base surface;
(c2) a projection length by which each of the lateral cleats projects in the width direction from the outer peripheral edge of the base surface is greater in the second engaging surface than in the second opposing surface, and wherein;
the first engaging surface of each of the medial cleats faces toward a posterior direction or an obliquely posterior direction; and
the second engaging surface of each of the lateral cleats faces toward an anterior direction or an obliquely anterior direction.

Abstract
A plurality of rubber-made medial cleats project from a base surface of an outsole in a medial portion of a forefoot portion, and a plurality of rubber-made lateral cleats project from the base surface of the outsole in a lateral portion of the forefoot portion, wherein a first engaging surface of each of the medial cleats faces toward a posterior direction or an obliquely posterior direction and a second engaging surface of each of the lateral cleats faces toward an anterior direction or an obliquely anterior direction.
