1. An article of footwear having an upper and a sole structure secured to the upper, at least a portion of the upper comprising:

  • a plurality of lace-receiving elements;

    a base layer extending from the lace-receiving elements to the sole structure, the base layer having at least one surface;

    a plurality of first strands having a substantially vertical orientation and extending from an area proximal to the lace-receiving elements to an area proximal to the sole structure, the first strands laying substantially parallel to the surface of the base layer in a region between the lace-receiving elements and the sole structure, and the first strands having a first tensile strength; and

    a plurality of second strands having a rearwardly-angled orientation and extending from the area proximal to the lace-receiving elements to the area proximal to the sole structure, the second strands laying substantially parallel to the surface of the base layer in the region between the lace-receiving elements and the sole structure, and the second strands having a second tensile strength that is at least fifty percent greater than the first tensile strength.
