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 polymer matrix structure that defines a plurality of apertures, wherein the polymer matrix structure extends as a unitary structure from a medial side of the article of footwear through a toe portion to a lateral side of the article of footwear to form a major portion of at least a forefoot portion and a midfoot portion of the article of footwear;
incorporating the polymer matrix structure into an upper, the upper having an edge that defines a throat area that forms an ankle opening of the upper and the throat area having a closure mechanism;
providing a strap that extends from a first side of the upper to a second side of the upper to provide a heel or ankle engaging system; and
securing a sole member to the upper.
2. The method recited in claim 1 , wherein the strap includes a first fastener element and at least one of the upper or the sole member includes a second fastener element that engages with the first fastener element to thereby allow the strap to be releasably engaged.
3. The method recited in claim 2 , wherein the first fastener element and the second fastener element form a hook-and-loop type connection.
4. The method recited in claim 1 , wherein the polymer matrix structure is formed from as a flat structure.
5. The method recited in claim 1 , wherein the polymer matrix structure is symmetrical about an axis extending in a front-to-rear direction of the polymer matrix structure.
6. The method recited in claim 1 , wherein the step of forming the polymer matrix structure includes forming a plurality of elongated and intersecting segments, the plurality of apertures being formed between the segments.
7. The method recited in claim 1 , wherein the plurality of apertures has a substantially quadrilateral shape.
8. The method recited in claim 1 , wherein the polymer matrix structure is formed by a molding process.
9. A method of manufacturing an article of footwear, comprising:
forming a polymer matrix structure as a flat structure, the matrix structure being formed from a plurality of segments that cross each other to define a plurality of intersections and apertures, at least a portion of the intersections each defining a first angle and a second angle, the first angle being an acute angle oriented in a substantially vertical direction, and the second angle being an obtuse angle oriented in a substantially horizontal direction, wherein the polymer matrix structure to form a major portion of at least a forefoot portion and a midfoot portion of the article of footwear;
incorporating the polymer matrix structure into an upper;
providing a strap that extends from a first side of the upper to a second side of the upper to provide a heel or ankle engaging system; and
securing a sole member to the upper.
10. The method recited in claim 9 , wherein the strap includes a first fastener element and at least one of the upper or the sole member includes a second fastener element that engages with the first fastener element to thereby allow the strap to be releasably engaged.
11. The method recited in claim 10 , wherein the first fastener element and the second fastener element form a hook-and-loop type connection.
12. The method recited in claim 9 , further comprising connecting an intermediate footwear structure to the upper around an ankle opening area.
13. The method recited in claim 9 , wherein the polymer matrix structure is symmetrical about an axis extending in a front-to-rear direction of the polymer matrix structure.
14. The method recited in claim 9 , wherein the step of forming the polymer matrix structure includes forming a plurality of elongated and intersecting segments, the plurality of apertures being formed between the segments.
15. The method recited in claim 9 , wherein the plurality of apertures has a substantially quadrilateral shape.
16. The method recited in claim 9 , wherein the polymer matrix structure is formed by a molding process.
17. A method of manufacturing an article of footwear, comprising:
forming a polymer matrix structure that defines a plurality of apertures, wherein the polymer matrix structure is formed as a flat unitary structure using a molding process to form a major portion of at least a forefoot portion and a midfoot portion of the article of footwear, wherein the polymer matrix structure extends as a unitary structure from a medial side of the article of footwear through a toe portion to a lateral side of the article of footwear, and wherein the plurality of apertures has a substantially quadrilateral shape;
incorporating the polymer matrix structure into an upper, the upper having an edge that defines a throat area that forms an ankle opening of the upper and the throat area having a closure mechanism;
providing a strap that extends from a first side of the upper to a second side of the upper to provide a heel or ankle engaging system; and
securing a sole member to the upper.
18. The method recited in claim 17 , wherein the strap includes a first fastener element and at least one of the upper or the sole member includes a second fastener element that engages with the first fastener element to thereby allow the strap to be releasably engaged.
