Abstract

Article of footwear comprising a midsole, the midsole comprises an opening and closing component such as zippers or Velcro. During the manufacturing process of lasting construction, a shoe last can put into a shoe upper integrated with the midsole through the released opening and closing component of midsole to finish the put-on last step. After the opening and closing component of midsole is sealed, a procedure similar to broad lasting is finished, and a sole laying step and a formation step can be continued.

Claims

1. A midsole of a shoe, comprising:

at least two lead frames;

a midsole body having an opening;

an opening and closing component disposed along the opening edges to open and close the opening.

2. A midsole of a shoe as claimed in claim 1, wherein the opening and closing component is two fabrics having corresponding structures, which are respectively fixed on both sides of the opening.

3. A midsole of a shoe as claimed in claim 1, wherein when the opening and closing component is fully opened, the midsole of the shoe is divided into two completely separated half midsole.

4. A midsole of a shoe as claimed in claim 2, wherein when the opening and closing component is fully opened, the midsole of the shoe is divided into two completely separated half midsole.

5. A midsole of a shoe as claimed in claim 1, wherein the opening and closing component is a hook-and-loop fastener.

6. A midsole of a shoe as claimed in claim 1, wherein the opening and closing component is a zipper.

7. A midsole of a shoe as claimed in claim 6, wherein the zipper comprises a slider, a bottom stop, and a chain tooth.

8. A midsole of a shoe as claimed in claim 7, wherein the slider is flat, and the thickness of the zipper is approximately equivalent to the thickness of the midsole body.

9. An article of footwear comprising:

an upper; and

a midsole comprising;

a midsole body having an opening; and

an opening and closing component disposed along the opening edges to open and close the opening;

wherein the upper is combined with the periphery of the midsole to provide a foot space into which the foot extends.

10. An article of footwear as claimed in claim 9, wherein the upper and the midsole can be integrated into one by sewing.

11. An article of footwear as claimed in claim 9, wherein the opening and closing component is a hook-and-loop fastener.

12. An article of footwear as claimed in claim 9, wherein the opening and closing component is a zipper.

13. An article of footwear as claimed in claim 12, wherein the zipper comprises a slider, a bottom stop, and a chain tooth.

14. An article of footwear as claimed in claim 13, wherein the zipper further comprises a top stop.

15. An article of footwear as claimed in claim 9, further comprising:

a shoe sole, in close contact with the midsole outside the foot space;

an insole, stacked over the midsole in the foot space.

16. A method for manufacturing footwear, comprising:

providing a midsole having an opening and an opening and closing component;

combining the midsole with an upper;

releasing the opening and closing component, passing a last through the opening, into the foot space formed by the upper and the midsole;

adjusting the position of the last to abut the upper and the midsole;

closing the opening and closing component to close the opening.

17. A method for manufacturing footwear as claimed in claim 16, wherein the opening and closing component is a hook-and-loop fastener.

18. A method for manufacturing footwear as claimed in claim 16, wherein the opening and closing component is a zipper.

19. A method for manufacturing footwear as claimed in claim 17, wherein the inner surface of the upper close to the toe and the heel has the structure of hook-and-loop fastener corresponding to the relative hook-and-loop part of the midsole.

20. A method for manufacturing footwear as claimed in claim 18, wherein, after the zipper is tightened and closed, the slider of the zipper is disengaged from the midsole.
