Abstract

A method for manufacturing a shoe, the method including the steps of: attaching a sock-shaped base member 1 forming a portion of an upper to a last portion 52 of a core 50, the core 50 including a core print 51 and the last portion 52; attaching the core 50 to an outer mold 61, 62; supplying a molten resin 71, 72 to be a reinforcement member 2 and/or a sole member 3, 4 into between the outer mold 61, 62 and the base member 1; and allowing the molten resin 71, 72 to cure, thereby forming the reinforcement member 2 and/or the sole member 3, 4 integral with the base member 1.

Claims

1. A shoe comprising an upper, the upper comprising:

a sock-shaped base member of a knit fabric, a knit-like fabric and/or a woven fabric; and

a reinforcement member with the base member the reinforcement member being substantially without sewn to the base member, and the reinforcement member being bonded and/or welded to a surface of the base member.

2. A shoe according to claim 1, wherein the reinforcement member covers at least a portion of a medial-side surface and a lateral-side surface.

3. A shoe according to claim 2, wherein the reinforcement member covers a portion of each of a front foot section, a middle foot section and a rear foot section on the medial-side surface, and covers a portion of each of the front foot section, the middle foot section and the rear foot section on the lateral-side surface.

4. A shoe according to claim 3, wherein the reinforcement member covers a portion of a bottom surface of a foot and continuously extends from the bottom surface of the foot onto the opposite side surfaces of the foot.

5. A shoe according to claim 4, wherein the reinforcement member covers a bottom surface of the middle foot section.

6. A shoe according to claim 5, wherein in the middle foot section, the reinforcement member continuously extends from the bottom surface onto the opposite side surfaces.

7. A shoe according to claim 6, wherein the reinforcement member includes a lacing loop integrally formed along an upper edge of the reinforcement member.

8. A shoe according to claim 6, wherein the reinforcement member includes an ornamental eyelet integrally formed along an upper edge of the reinforcement member.

9. A shoe according to claim 6, wherein the reinforcement member covers a circumference of a top line.

22. A shoe according to claim 1, wherein:

the reinforcement member comprises a pair of side surface portions extending in an up-down direction along each of a medial-side surface and a lateral-side surface of a middle foot section of a foot, a lower portion extending in a front-rear direction in a lower portion of the side surfaces, and an ornamental eyelet extending in the front-rear direction along an instep of the foot and having a plurality of lacing apertures; and

a portion of the base member is enclosed, over an entire circumference thereof, by the pair of side surface portions, the lower portion and the ornamental eyelet.

23. A shoe according to claim 22, wherein the lacing apertures are provided near upper ends of the side surface portions extending from the lower portion toward the ornamental eyelet.

10. A shoe comprising:

a sock-shaped base member of a knit fabric, a knit-like fabric and/or a woven fabric forming a portion of an upper; and

a sole member made of a resin bonded and/or welded to a bottom surface of the base member.

11. A shoe according to claim 10, wherein the resin is a foamed material, and the sole member is a midsole member.

12. A shoe according to claim 11, wherein on a medial-side surface and a lateral-side surface of a foot, the midsole member covers a portion of each side surface of the foot.

13. A shoe according to claim 12, wherein the midsole member covers opposite side surfaces of a middle foot section, and a lacing aperture is formed along an upper edge of the midsole member.

14. A shoe according to claim 11, wherein a heel counter is integrally formed with the midsole member.

15. A shoe according to claim 11, wherein the midsole member covers a circumference of a top line.

24. A shoe according to claim 10, wherein:

the sole member comprises a pair of side surface portions extending in an up-down direction along each of a medial-side surface and a lateral-side surface of a middle foot section of a foot, a roll-up lower portion rolled up from a bottom surface and extending in a front-rear direction in a lower portion of the side surfaces, and an upper edge portion extending in the front-rear direction along an instep of the foot and having a plurality of lacing apertures 304; and

a portion of the base member is enclosed, over an entire circumference thereof, by the pair of side surface portions, the roll-up lower portion and the upper edge portion.

25. A shoe according to claim 24, wherein the lacing apertures are provided near upper ends of the side surface portions extending from the lower portion toward the upper edge portion.

16. A method for manufacturing a shoe, the method comprising the steps of:

attaching a sock-shaped base member forming a portion of an upper to a last portion of a core, the core including a core print and the last portion;

loading the core onto an outer mold;

supplying a molten resin to be a reinforcement member and/or a sole member into between the outer mold and the base member; and

allowing the molten resin to cure, thereby forming the reinforcement member and/or the sole member integral with the base member.

17. A manufacturing method according to claim 16, wherein in the step of loading the core, the core print of the core his supported by the outer mold, with the core print protruding from a top line of the base member.

18. A manufacturing method according to claim 17, wherein the loading step is performed with the core positioned so that the core print is below the last portion.

19. A manufacturing method according to claim 18, wherein:

the outer mold includes a first outer mold, to which the core print is attached, and a second outer mold meshing with the first outer mold, the method comprising;

a first supply step of supplying a first molten resin to be the reinforcement member into between the first outer mold and the second outer mold and the last portion;

a step of allowing the first molten resin to cure, thereby forming the reinforcement member integral with the base member;

a step of meshing a third outer mold, which meshes with the first outer mold, onto the first outer mold, replacing the second outer mold;

a second supply step of supplying a second molten resin to be the sole member into between the third outer mold and the last portion; and

a step of allowing the second molten resin to cure, thereby forming the sole member integral with the base member.

20. A manufacturing method according to claim 19, wherein in the meshing step after the first supply step, the second outer mold is removed, with the core print remaining attached to the first outer mold, and the third outer mold is meshed onto the first outer mold, replacing the second outer mold.

21. A method for manufacturing a shoe, the method comprising the steps of:

attaching a sock-shaped base member made of a knit fabric and/or a woven fabric forming a portion of an upper to a last and heating the sock-shaped base member, thereby forming a sock portion; and

heating a sole member made of a knit fabric and/or a woven fabric integral with the base member during the heating of the base member, thereby melting the sole member.
