First Claim
Patent Images
1. An article of footwear comprising:
- an upper including a matrix structure extending along at least one of a medial side and a lateral side of the footwear, 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; and
a sole structure secured to the upper.

Abstract
An article of footwear is disclosed that includes an upper and a sole structure. The upper includes a matrix structure that defines a plurality of apertures. The apertures may have an elongate configuration to impart differences in the extensibility of the upper in different directions. For example, the matrix layer may be formed from a plurality of segments that cross each other to define the apertures. A method of manufacturing the article of footwear is also disclosed.

15. An article of footwear comprising:
-
an upper including a matrix structure that defines a first edge and an opposite second edge, the matrix structure being formed from a plurality of elongate segments that extend between the first edge and the second edge, the segments defining a plurality of intersections and apertures, the intersections being locations where two of the segments cross each other, and the apertures being areas between the segments, at least a portion of the intersections defining a first pair of angles and a second pair of angles, the first pair of angles being acute angles oriented in a direction that is substantially perpendicular to the first edge and the second edge, and the second pair of angles being obtuse angles oriented in a direction that is substantially parallel to the first edge and the second edge; and
a sole structure secured to the upper. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. An article of footwear comprising:
-
an upper having a polymer layer extending along at least a medial side and a lateral side of the footwear, the polymer layer defining a plurality of apertures with an elongate configuration oriented to extend substantially perpendicular to a longitudinal axis of the footwear, the longitudinal axis extending between a forefoot region and a heel region of the footwear; and
a sole structure secured to the upper. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)

59. A method of manufacturing a first article of footwear and a second article of footwear, the method comprising steps of:
-
forming a first polymer element with a mold, the first polymer element defining a plurality of first apertures with an elongate configuration;
securing the first polymer element to a first sole structure to form at least a portion of a first upper, the first sole structure having a first length;
forming a second polymer element that is substantially identical to the first polymer element with the mold; and
securing the second polymer element to a second sole structure to form at least a portion of a second upper, the second sole structure having a second length, the second length being greater than the first length. - View Dependent Claims (60, 61, 62, 63, 64, 65, 66)
