  • the present invention relates to a shoe, and more particularly to a shoe upper which can maintain a stable shoe structure and can be attached to a sole assembly lacking part of a midsole, a method of manufacturing a shoe, and a shoe having a function of improving the wearer's health.
  • a shoe absorb shocks and protect wearer's feet when wearers move.
  • a shoe is generally manufactured by first setting up the basic shoe structure by bonding the midsole to the entire lower end of the shoe upper and then by bonding the midsole to the outsole.
  • Korean Patent 627728 discloses a known technique in which the outsole is divided into an upper layer and a lower layer. Further, part of the outsole, made of a cushiony material, protrudes upward into the shoe through the opening formed in the midsole and the upper layer of the outsole, so that the cushion of the outsole comes into direct contact with the heel of a wearer. Thanks to this structure, the wearer can feel cushioned and comfortable when the wearer walks while wearing the shoe.
  • the basic shoe structure is set up in a way that the shoe upper is combined with the outsole in the presence of the midsole therebetween. Accordingly, direct contact between the sole of a wearer's foot and the outsole of the shoe can only be accomplished using a midsole having an aperture through which part of the outsole is visible.
  • the technique of using the midsole with an aperture is disadvantageous in that the aperture size is not sufficiently large because the area of the midsole in which the aperture can be formed is limited. That is, the aperture can be provided only in a portion of the midsole other than a bonding region in which the shoe upper and the midsole are bonded to each other.
  • the sole of a wearer's foot cannot sufficiently contact the outsole of a shoe, so that the functions imparted to the outsole cannot be sufficiently performed when the wearer walks.
  • the object of the invention is to provide a shoe upper capable of forming a basic shoe structure, which can be attached to a sole assembly lacking part of a midsole, and a method of manufacturing a shoe using the shoe upper.

  • a shoe upper which constitutes a shoe by being attached to a sole assembly, including 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.
  • the coupling member be a string sewn along the first part of the opening and that the shoe upper further comprise a midsole attached to a second part of the opening at a position in which the constriction lace is not provided.
  • the midsole have a flexible member at a position corresponding to the first part of the opening, which is surrounded by the constriction lace.
  • a method of manufacturing a shoe including a step of setting up a basic shoe structure corresponding to a form of a shoe last using a shoe upper by placing the shoe last into the shoe upper and then constricting an opening of a lower open end of the shoe upper by pulling the constriction lace, processing the constriction lace so that a knot of the constriction lace does not come to be untied, and completing the shoe, the sole assembly of which protrudes upward through the opening in the shoe upper, by attaching the shoe upper to the sole assembly.
  • the coupling member be a string sewn to a boundary of the opening of the shoe upper in a manner of surrounding the constriction lace and that the processing be performed by constricting the opening by pulling the constriction lace, forming a knot, and making the knot flat.
  • the opening be constricted after a midsole is attached to part of the shoe upper, the part not being surrounded by the constriction lace.
  • a shoe constituted by attaching a shoe upper to a sole assembly, in which the sole assembly is visible inside the shoe, wherein the sole assembly has a cushion which is thickest in the middle portion thereof and becomes thicker going to the front end and the back end thereof, respectively, and wherein the cushion is pressed at the front portion and the back portion by the weight of a wearer, so that the overall slope of the sole assembly is changed when the wearer wears the shoe.
  • the sole assembly include an upper midsole which is thickest in the middle portion thereof and becomes thinner going to the front end and the back end thereof, a lower midsole which is thinnest in the middle portion thereof and becomes thicker going to the front end and the back end thereof, and an outsole having abrasion resistance and being attached to the lower surface of the lower midsole, in which pumping chambers are provided in the front portion and the 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 out air from the pumping chambers into the shoe upper.

  • the shoe upper, the shoe, and the manufacturing of the shoe according to the invention have the following advantages. Since the midsole has a large size opening which cannot be obtained through known shoe manufacturing techniques, it is possible to enhance the advantageous effects of the shoe, in which a variety of functions are imparted to the sole assembly and the functions are performed under a condition such that the sole of the wearer's foot can directly contact the sole assembly of the shoe.
  • the shoe of the wearer's foot can effectively press the pumping chambers provided in the sole assembly. Accordingly, air in the sole assembly and the inside of the shoe can be forcibly circulated, and this contributes to an improvement of the wearer's health. Further, thanks to the specific structure of the sole assembly provided in the shoe of the invention, the wearer can obtain a mountain climbing effect and feel comfortable when the wearer walks while wearing the shoe.
