Abstract

A sole includes a sole body supporting an entire planta of a wearer, lower protrusions protruding downward from a lower portion of the sole body toward the ground and spaced from each other, and upper protrusions protruding upward from an upper portion of the sole body toward a planta of a wearer, each of the upper protrusions being on the sole body and overlapping with an associated one of the lower protrusions. Each of the lower protrusions has, at its lower portion, a first region which makes contact with the ground, and each of the upper protrusions has, at its upper portion, a second region which makes contact with the planta of the wearer and is smaller than the first region.

         3 . The sole structure of  claim 1 , wherein
 the second regions of the upper protrusions vary in size depending on their positions with respect to portions of the planta of the wearer.   
     
     
         4 . The sole structure of  claim 1 , wherein
 the upper protrusions vary in height depending on their positions with respect to portions of the planta of the wearer.
