the ribbon structure comprises:
a backing layer,
wherein the first layer is a first ribbon layer including the first ribbon portion, and
wherein the second layer is a second ribbon layer including the second ribbon portion; and
the second ribbon layer overlaps the first ribbon layer at selected locations to form the first and second nodes.
8. The article of footwear according to claim 7 , wherein the first ribbon layer and the second ribbon layer form a lattice.
9. The article of footwear according to claim 7 , wherein the first ribbon layer is secured to the backing layer via stitching.
10. The article of footwear according to claim 7 , wherein the ribbon structure defines a plurality of links and a plurality of nodes, each link comprising a section of ribbon extending between two adjacent nodes.
11. The article of footwear according to claim 7 , wherein the border is an embroidered structure.
12. The article of footwear according to claim 1 , wherein:
the first layer and the second layer intersecting at the nodes includes the second layer overlapping the first layer at selected locations to define the nodes; and
