Structure of shoes uppers, a manufacturing method of shoes and a structure of shoes

Abstract

The present invention relates to a shoe, a shoe upper which maintains a stable shoe form and can be attached to a sole assembly lacking part of a midsole, a method of manufacturing the shoe, and a shoe capable of improving a wearer's health. The shoe upper, attached to the sole assembly so as to constitute a shoe, has a constriction lace which surrounds a first part of an opening thereof, which directs the sole assembly and a coupling member for coupling the constriction lace to the shoe upper in a manner such that the constriction lace can constrict or loosen the opening.

1 . A shoe upper which constitutes a shoe by being attached to a sole assembly, comprising:
 a constriction lace provided at a first part of an opening of the shoe upper which directly contacts the sole assembly; and   a coupling member for coupling the constriction lace to the shoe upper in a manner such that the constriction lace constricts or loosens the first part of the opening of the shoe upper.   
     
     
         2 . The shoe upper according to  claim 1 , wherein the coupling member is a string sewn along a boundary of the first part of the opening of the shoe upper. 
     
     
         3 . The shoe upper according to  claim 1 , further comprising a midsole attached to a second part of the opening at a position at which the constriction lace is not provided. 
     
     
         4 . The shoe upper according to  claim 3 , wherein a flexible member is provided in the first part of the opening of the shoe upper, which is surrounded by the constriction lace. 
     
     
         5 . A method of manufacturing a shoe which is manufactured by attaching a shoe upper having a constriction lace surrounding a first part of an opening of the shoe upper, which directly contacts a sole assembly, and a coupling member for coupling the shoe lace to the first part of the shoe upper so that the constriction lace constricts or loosens the first part of the opening, to the sole assembly, comprising:
 setting up a basic shoe structure by placing a shoe last into the shoe upper and then constricting the first part of the opening by pulling the constriction lace so that the opening comes to have a form corresponding to a form of the shoe last; processing the constriction lace so that a knot of the constriction lace does not come untied; and   completing the shoe in which the sole assembly is visible through the opening of the shoe upper by attaching the shoe upper to the sole assembly.   
     
     
         6 . The method according to  claim 5 , wherein the coupling member is a string sewn to a boundary of the first part of the opening of the shoe upper in a manner of surrounding the constriction lace. 
     
     
         7 . The method according to  claim 5 , wherein the processing is performed by constricting the opening by pulling the constriction lace, forming a knot, and pounding the knot to be flat. 
     
     
         8 . The method according to  claim 7 , wherein the opening is constricted after a midsole is attached to a second part of the shoe upper, the second part not being surrounded by the constriction lace. 
     
     
         9 . A shoe having a shoe upper with an opening which is near a sole assembly and the sole assembly being visible inside the shoe, thanks to a structure in which the shoe upper is attached to the sole assembly after a basic shoe structure is set up by constricting part of the opening of the shoe upper using a constriction lace, wherein the sole assembly has a cushion which is thickest in a middle portion thereof and becomes thicker as it goes to a front end and a back end thereof, respectively, and wherein the cushion is pressed at a front portion and a back portion by weight of a wearer, so that the overall slope of the sole assembly is changed when the wearer wears the shoe. 
     
     
         10 . The shoe according to  claim 9 , wherein the sole assembly includes:
 an upper midsole which is thickest in a middle portion thereof and becomes thinner as it goes to a front end and a back end, respectively, thereof;   a lower midsole which is thinnest in a middle portion thereof and becomes thicker as it goes to a front end and a back end, respectively, thereof; and   an outsole having abrasion resistance and attached to a lower surface of the lower midsole.   
     
     
         11 . The shoe according to claim in wherein pumping chambers are provided in a front portion and a back portion of the shoe by combining the upper midsole and the lower midsole, an air circulation passage is provided between the pumping chambers, and at least one air discharge hole is provided to the upper midsole in order to discharge air from the pumping chambers into the shoe upper. 
     
     
         12 . The shoe according to  claim 11 , wherein the air circulation path is constituted by a connection groove formed between a front pumping chamber and a back pumping chamber provided to the upper midsole and a connection groove formed between a front pumping chamber and a back pumping chamber provided to the lower midsole. 
     
     
         13 . The shoe according to  claim 11 , wherein a shock absorbing member is provided to the pumping chamber in the lower midsole in order to absorb shocks attributable to pumping operation. 
     
     
         14 . The shoe upper according to  claim 2 , further comprising a midsole attached to a second part of the opening at a position at which the constriction lace is not provided. 
     
     
         15 . The method according to  claim 6 , wherein the processing is performed by constricting the opening by pulling the constriction lace, forming a knot, and pounding the knot to be flat.
