A sole of a shoe includes a forefoot support portion R1 that supports a forefoot of a foot of a wearer, a midfoot support portion that supports a midfoot of the foot of the wearer, and a rearfoot support portion that supports a rearfoot of the foot of the wearer, which are connected in order from a front side toward a rear side. A ground contact portion having a portion positioned on a lowermost line connecting a lowermost point of the forefoot support portion and a lowermost point of the rearfoot support portion in a side view is formed in a medial-foot-side region of a bottom surface of the midfoot support portion. A protrusion protruding toward the medial foot side is formed on a medial-foot-side side surface of the midfoot support portion.
