Footwear

Abstract

The present disclosure relates to footwear. The footwear according to an embodiment of the present disclosure includes a first sole having a first base portion configured to come into contact with the ground surface, and a plurality of first protrusion portions protruding from the base portion in a direction opposite to the ground surface, and a second sole having a second base portion bonded to ends of the plurality of first protrusion portions, and a plurality of second protrusion portions protruding from the second base portion in the direction of the first base portion and having ends bonded to the first base portion.

1 . Footwear comprising:
 a first sole having a first base portion configured to come into contact with a ground surface, and a plurality of first protrusion portions protruding from the base portion in a direction opposite to the ground surface; and   a second sole having a second base portion bonded to ends of the plurality of first protrusion portions, and a plurality of second protrusion portions protruding from the second base portion in a direction of the first base portion and having ends bonded to the first base portion.   
     
     
         2 . The footwear of  claim 1 , wherein the plurality of first protrusion portions and the plurality of second protrusion portions each have a shape having a horizontal cross-sectional area that increases in a direction in which the plurality of first protrusion portions and the plurality of second protrusion portions each protrude. 
     
     
         3 . The footwear of  claim 1 , wherein the plurality of first protrusion portions and the plurality of second protrusion portions each include a hemispherical shape. 
     
     
         4 . The footwear of  claim 3 , wherein the plurality of first protrusion portions and the plurality of second protrusion portions each have a hollow hemispherical shape. 
     
     
         5 . The footwear of  claim 4 , wherein the plurality of first protrusion portions has a hollow hemispherical shape, a portion of the hollow hemispherical shape, which faces the ground surface, is opened, and an inner surface of the hollow hemispherical shape is exposed to the ground surface. 
     
     
         6 . The footwear of  claim 1 , wherein the first sole and the second sole are different in hardness from each other. 
     
     
         7 . The footwear of  claim 6 , wherein the plurality of first protrusion portions or the plurality of second protrusion portions, which has relatively high hardness among the plurality of first protrusion portions and the plurality of second protrusion portions, is formed along an edge of the first base portion or the second base portion, and
 wherein the plurality of first protrusion portions or the plurality of second protrusion portions, which has relatively low hardness among the plurality of first protrusion portions and the plurality of second protrusion portions, is disposed in spaces between the plurality of first protrusion portions or the plurality of second protrusion portions having relatively high hardness.   
     
     
         8 . The footwear of  claim 7 , wherein the plurality of first protrusion portions or the plurality of second protrusion portions, which has relatively low hardness among the plurality of first protrusion portions and the plurality of second protrusion portions, has relatively higher elasticity than the plurality of first protrusion portions or the plurality of second protrusion portions having relatively high hardness. 
     
     
         9 . The footwear of  claim 7 , wherein the first base portion has a plurality of first connection portions configured to connect all or some of the plurality of first protrusion portions, and
 wherein the second base portion has a plurality of second connection portions configured to connect all or some of the plurality of second protrusion portions.   
     
     
         10 . The footwear of  claim 9 , wherein the plurality of first connection portions each has a smaller height than each of the plurality of first protrusion portions,
 wherein a height of each of the plurality of first connection portions decreases as a distance from each of the plurality of first protrusion portions increases,   wherein the plurality of second connection portions each has a smaller height than each of the plurality of second protrusion portions, and   wherein a height of each of the plurality of second connection portions decreases as a distance from each of the plurality of second protrusion portions increases.   
     
     
         11 . The footwear of  claim 9 , wherein the plurality of first connection portions connects the plurality of first protrusion portions in a longitudinal direction or a width direction of the first base portion,
 wherein the plurality of second connection portions connects the plurality of second protrusion portions in a width direction or a longitudinal direction of the second base portion, and   wherein the plurality of first connection portions and the plurality of second connection portions are formed in a direction in which the plurality of first connection portions and the plurality of second connection portions intersect one another.   
     
     
         12 . The footwear of  claim 7 , wherein the first sole further comprises a first elastic reinforcement portion protruding from the first base portion in a direction of the second base portion, and
 wherein the second sole further comprises a second elastic reinforcement portion protruding from the second base portion in a direction of the first base portion and having an end facing and bonded to an end of the first elastic reinforcement portion.   
     
     
         13 . The footwear of  claim 12 , wherein the first elastic reinforcement portion and the second elastic reinforcement portion are disposed between the plurality of first protrusion portions and the plurality of second protrusion portions. 
     
     
         14 . The footwear of  claim 12 , wherein one of or both of the first elastic reinforcement portion and the second elastic reinforcement portion each have a hemispherical shape.
