Article with ribbon structure having nodes and links
An article of footwear with an upper including a ribbon structure is disclosed. The ribbon structure comprises ribbon sections running in at least two different directions. Ribbon sections are connected at nodes. Between nodes portions of ribbon act like links joining the nodes. The links can be arranged in various geometries, including a rectangular grid and a triaxial grid. The ribbon structure may extend the entire length of the article of footwear, and may extend through a forefoot, midfoot and heel.
