Abstract: A shoe is configured such that front and back clearances, which are respectively provided between a front wall surface of a second receiving portion and a front end of a second buffering member received in the second receiving portion and between a back wall surface of the second receiving portion and a back end of the second buffering member received in the second receiving portion, permit the second buffering member made of an elastic material to move in a longitudinal direction in the second receiving portion when a ground surface of an outsole contacts the ground and the weight of a human body is put on a heel support surface.

Abstract: The invention is directed to transmitting ground surface information to a foot sole of a shoe wearer accurately. Sole structure 1 includes a sole body 2 having a sole bottom surface 20 on a ground surface side and a sole top surface 21 on the opposite side thereof, a plurality of first protrusions 3 formed of elastic member and disposed on the sole bottom surface 20, and a plurality of second protrusions 4 formed of elastic member, disposed on the sole top surface 21 and located at positions corresponding respectively to positions of the first protrusions 3. A sectional shape of the first protrusion 3 is formed so that it gradually becomes smaller as it leaves the sole bottom surface 20. A distal end portion of the first protrusion 3 is formed of an arcuate shaped surface that protrudes downwardly. A sectional shape of the second protrusion 4 is formed so that it gradually becomes smaller as it leaves the sole top surface 21.
