Article of footwear having an upper with a matrix layer
Articles of footwear, including athletic footwear, include one or more of: (a) a sole structure; (b) an upper having lateral and medial side elements engaged with the sole structure, the upper made from a polymer matrix structure that extends through at least a heel region; (c) a size adjustment mechanism located at the heel region; (d) a heel tongue element located adjacent the size adjustment mechanism; (e) a shoe securing mechanism; (f) an instep tongue member; and/or (g) a bootie member located at least partially within the foot-receiving chamber. Methods of manufacturing such articles of footwear also are disclosed.
1. A method of manufacturing an article of footwear, comprising:
forming a unitary, one piece polymer matrix structure that defines a plurality of apertures separated by polymer segments, the polymer matrix structure formed from a flat member that is symmetrical about an axis extending in a front-to-rear direction, wherein the polymer matrix structure includes a first free end and a second free end;
incorporating the polymer matrix structure into an upper such that the first free end extends along a heel region of the upper and the second free end extends along the heel region of the upper;
engaging the first free end and the second free end; and
securing a sole member to the upper.
2. The method recited in claim 1 , wherein the first free end includes a plurality of openings and the second free end includes a plurality of openings, and wherein the engaging includes passing a cord between the openings of the first and second free ends.
3. The method recited in claim 1 , wherein the first free end includes a first engagement structure and the second free end includes a second engagement structure, and wherein the engaging includes connecting an intermediate member between the first engagement structure and the second engagement structure.
4. The method recited in claim 1 , wherein the first free end includes a first engagement structure and the second free end includes a second engagement structure, and wherein the engaging includes engaging the first engagement structure to the second engagement structure.
5. The method recited in claim 1 , wherein the polymer matrix structure extends as a unitary structure to form at least a major portion of a forefoot portion, a midfoot portion, and the heel region of the article of footwear.
6. The method recited in claim 1 , further comprising:
engaging a heel tongue element with at least one of the upper or the sole structure, wherein the heel tongue element is engaged at the heel region adjacent the first free end and the second free end.
7. The method recited in claim 6 , further comprising:
releasably engaging a bootie member with the heel tongue element.
8. The method recited in claim 1 , further comprising:
inserting a bootie member into a foot-receiving chamber at least partially defined by the upper.
9. The method recited in claim 1 , wherein the first free end and the second free end are fixed together at a lap joint seam.
10. A method of manufacturing an article of footwear, comprising:
forming a unitary, one piece polymer matrix structure that defines a plurality of apertures separated by polymer segments, the polymer matrix structure formed from a flat member that is symmetrical about an axis extending in a front-to-rear direction, wherein the polymer matrix structure extends as a unitary structure to form a major portion of at least a forefoot portion, a midfoot portion, and a heel portion of the article of footwear;
incorporating the polymer matrix structure into an upper;
securing a sole member to the upper; and
engaging a heel tongue element with at least one of the upper or the sole member.
11. The method recited in claim 10 , further comprising:
releasably engaging a bootie member with the heel tongue element.
12. The method recited in claim 10 , further comprising:
releasably engaging a bootie member within a foot-receiving chamber at least partially defined by the upper.
13. The method recited in claim 10 , further comprising:
providing a footwear securing mechanism over a throat area defined in the upper member.
14. The method recited in claim 13 , further comprising:
engaging a tongue member adjacent the footwear securing mechanism and adjacent a foot-receiving chamber at least partially defined by the upper.
15. The method recited in claim 14 , wherein the tongue member is releasably engaged with the upper.
16. The method recited in claim 10 , wherein the heel tongue element is releasably engaged with at least one of the upper or the sole member.
17. The method recited in claim 16 , wherein the heel tongue element is releasably engaged with at least one of the upper or the sole member, and whether the method further comprises:
releasably engaging a bootie member with the heel tongue element.
18. The method recited in claim 17 , further comprising:
providing a footwear securing mechanism over a throat area defined in the upper member; and
engaging a tongue member adjacent the footwear securing mechanism and adjacent a foot-receiving chamber at least partially defined by the upper.
19. The method recited in claim 18 , wherein the tongue member is releasably engaged with the upper.
20. The method recited in claim 10 , further comprising:
providing a size adjusting mechanism for the upper in the heel portion adjacent the heel tongue element.
