Shoe and method of manufacturing shoe

Abstract

A shoe includes an upper body covering at least an instep of a foot. The upper body includes a main material formed of a first thread body made of a chemically-similar material. At least a part of the main material is an embroidered portion formed by embroidering and/or sewing with a second thread body made of a chemically-similar material having a melting point lower than a melting point of the chemically-similar material. At least a part of the embroidered portion is a solidified portion having a high hardness.

1 . A shoe comprising
 an upper body covering at least an instep of a foot,   wherein the upper body includes a main material formed of a first thread body made of a chemically-similar material,   at least a part of the main material is an embroidered portion formed by embroidering and/or sewing with a second thread body made of a chemically-similar material having a melting point lower than a melting point of the chemically-similar material, and   at least a part of the embroidered portion is a solidified portion having a high hardness.   
     
     
         2 . The shoe according to  claim 1 ,
 wherein the chemically-similar material is a polyester-based material.   
     
     
         3 . The shoe according to  claim 2 ,
 wherein the chemically-similar material includes TPEE.   
     
     
         4 . The shoe according to  claim 1 ,
 wherein the upper body further covers a toe, and   the embroidered portion is located at an area of the embroidered portion corresponding to the toe.   
     
     
         5 . The shoe according to  claim 1 ,
 wherein the upper body further covers a heel, and   the embroidered portion is located at an area corresponding to the heel.   
     
     
         6 . The shoe according to  claim 1 ,
 wherein the upper body includes an eyelet, and   the embroidered portion is located around the eyelet.   
     
     
         7 . The shoe according to  claim 1 ,
 wherein at least a part of the second thread body is transparent and/or translucent.   
     
     
         8 . The shoe according to  claim 1 ,
 wherein at least a part of the second thread body is colored.   
     
     
         9 . The shoe according to  claim 8 ,
 wherein at least a part of the second thread body is a pre-colored thread.   
     
     
         10 . The shoe according to  claim 1 ,
 wherein at least a part of the second thread body is a monofilament.   
     
     
         11 . The shoe according to  claim 1 ,
 wherein at least a part of the second thread body is a multifilament.   
     
     
         12 . The shoe according to  claim 1 ,
 wherein the embroidered portion includes a portion whose hardness gradually changes.   
     
     
         13 . The shoe according to  claim 1 ,
 wherein the second thread body include a plurality of types having different melting points.   
     
     
         14 . The shoe according to  claim 1 ,
 wherein at least a part of the solidified portion has a smaller thickness than other parts of the main material.   
     
     
         15 . A method of manufacturing a shoe including an upper body covering at least an instep of a foot, the upper body including a main material formed of a first thread body made of a chemically-similar material, the method comprising:
 forming, on at least a part of the main material, an embroidered portion formed by embroidering and/or sewing with a second thread body made of a chemically-similar material having a melting point lower than a melting point of the chemically-similar material, and   forming a solidified portion having a high hardness on at least a part of the embroidered portion.
