1. A footwear article, comprising:
- an upper, at least a portion of which is formed via one or more slippably-engaged and intertwined cords configured to at least partially enclose a foot, at least one of the cords engaged with a sole, wherein a first cord of the one or more slippably-engaged and intertwined cords forms a first plurality of loops and a second cord of the one or more slippably-engaged and intertwined cords forms a second plurality of loops, wherein an upper loop region comprises a first loop of the first plurality of loops intertwined with and slidably movable relative to at least two loops of the second plurality of loops of a lower loop region, wherein a second loop of the at least two loops is intertwined with and slidably movable relative to at least two loops of the first plurality of loops including the first loop between the upper and lower loop regions, and where a loop intersecting midline, arranged along an interface between the upper and lower loop regions, comprises each of the first and second pluralities of loops, wherein the first cord forms lace attachment loops, and wherein a lace cord is intertwined with at least two loops of the lace attachment loops, and where a heel counter is adjacent to a heel side of the sole, and where the first loop and the second loop follow a single path around the heel counter wherein the heel counter is interlaced with one or more of the cords and where the heel counter has less flexibility than a cord structure, the cord structure comprising the upper loop region, the lower loop region, and the loop intersecting midline.

- 10. A footwear article comprising a looped upper with cords and a heel counter and is adjacent to a heel side of the sole forming a structure configured to enclose a foot, the cords in the upper in slippable engagement with respect to one another, but being fixedly attached at interfaces with a sole, wherein the cords form a cord structure with a first cord of the cords forms a first plurality of loops along a vamp and a second cord of the cords forms a second plurality of loops along a rand, wherein a loop of the first plurality of loops is in slippable engagement with at least two loops of the second plurality of loops, and wherein a loop of the second plurality of loops is in slippable engagement with at least two loops of the first plurality of loops, and where a midline arranged between the vamp and the rand of the footwear article comprises the first and second pluralities of loops intertwining, wherein the first and second pluralities of loops are displaced in a direction perpendicular to the midline and where the heel counter is interlaced with at least one of the cords following a single path around the heel counter, and where the heel counter has less flexibility than the cord structure.

14. A footwear article, comprising:
-
a cord structure comprising one or more slippably-engaged and intertwined cords configured to at least partially enclose a foot, at least one of the cords engaged with a sole, wherein a vamp comprises a first cord of the one or more slippably-engaged and intertwined cords-having a first plurality of loops and a rand comprises a second cord of the one or more slippably-engaged and intertwined cords having a second plurality of loops, wherein a first loop of the first plurality of loops is intertwined with and slidably movable relative to at least two loops of the second plurality of loops, wherein a second loop of the at least two loops of the second plurality of loops is intertwined with and slidably movable relative to at least two loops of the first plurality of loops including the first loop, wherein a beginning of each loop is substantially adjacent to an ending of each loop, and wherein a loop of the first cord is slippably-engaged along an entire length of a loop of the second cord, wherein a midline is arranged between the vamp and the rand, the first and second pluralities of loops being intertwined at the midline, and where the first and second pluralities of loops are slidably movable perpendicular to the midline, and where a heel counter adjacent to a heel side of the sole is interlaced with one or more of the cords and wherein the heel counter is interlaced with one or more of the cords and where the heel counter has less flexibility than a cord structure, the cord structure comprising the intertwined cords.
