Shoe sole and shoe having same

Abstract

The present invention, for the sake of a shoe sole having an improved effect of acupressure on the user's sole and enhanced durability and a shoe having the same, provides a shoe sole and a shoe having the same, the shoe sole comprising: a base; a protrusion positioned on the base; and a plurality of small protrusions positioned on the surface of the protrusion, wherein points at which the protrusion and the plurality of small protrusions meet have circular shapes with a diameter of a, and the distance b between the protrusion and the farthest points of the plurality of small protrusions from the protrusion is larger than a/2.

1 . A shoe sole comprising:
 a base;   a protrusion positioned on the base; and   a plurality of small protrusions positioned on the surface of the protrusion and having end points being farthest points from the protrusion,   wherein an edge of points at which the protrusion and the plurality of small protrusions meet is a closed curve having a length of the longest axis of a l , and a distance b between the protrusion and the farthest points of the plurality of small protrusions from the protrusion is larger than a 1 /2.   
     
     
         2 . The shoe sole of  claim 1 , wherein, when taking a line vertical to a surface of the protrusion at the end point of the plurality of small protrusions as the center axis, taking a point where the center axis meets the surface of the protrusion as a center point, taking as a minimum point a point on the closed curve a distance from which point to the center point is a minimum distance a 2 , and taking as α a distance, upon considering a vector starting from the minimum point and ending at the center point, from the center axis at a point half of the height of the plurality of small protrusions to the surface of the plurality of small protrusions in the vector direction, it is that b<2a 2 +2α. 
     
     
         3 . The shoe sole of  claim 1 , wherein the plurality of small protrusions are a form of rotational body having a center axis, and when taking α as the distance from the surface of the plurality of small protrusions at the point half on the height of the plurality of small protrusions to the center axis of the plurality of small protrusions, it is that b<a 1 +2α. 
     
     
         4 . The shoe sole of  claim 1 , wherein the plurality of small protrusions include a plurality of first small protrusions positioned at a distance of not 0 from the apex farthest from the base, and a distance from the base to a point farthest from the base of each of the plurality of first small protrusions is equal to or larger than a distance from the base to the apex. 
     
     
         5 . The shoe sole of  claim 4 , wherein the distances from the base to points farthest from the base of the plurality of first small protrusions are equal. 
     
     
         6 . The shoe sole of  claim 4 , wherein the plurality of first small protrusions are positioned at equal distance from the apex. 
     
     
         7 . The shoe sole of  claim 4 , wherein the plurality of small protrusions are not positioned at the apex of the protrusion. 
     
     
         8 . The shoe sole of  claim 4  further comprising second small protrusions positioned at the apex of the protrusion, wherein a distance from the base to a point farthest from the base of the second small protrusions is equal to or smaller than the distance from the base to a point farthest from the base of the plurality of first small protrusions. 
     
     
         9 . The shoe sole of  claim 1 , wherein the base, the protrusion and the plurality of small protrusions are integral. 
     
     
         10 . The shoe sole of  claim 1 , wherein an angle formed by the surface of the protrusion and a tangential plane tangential to the surface of the small protrusion at a point where the small protrusion and the protrusion meet is an obtuse angle. 
     
     
         11 . The shoe sole of  claim 1 , wherein the surface of the plurality of small protrusions and the surface of the protrusion are connected without a sharp point. 
     
     
         12 . The shoe sole of  claim 1  further comprising a plurality of protrusions, wherein a distance from the base to an apex of a protrusion corresponding to the center of an arch of the user's sole is longer than a distance from the base to an apex of a protrusion corresponding to a heel of the user. 
     
     
         13 . A shoe comprising a shoe sole of  claim 1 .
