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 that may move substantially independently of other nodes. The ribbon structure can provide strength along one of the directions and may simultaneously remain slack in the other direction.

A knitted upper for an article of footwear. The knitted upper is formed essentially as a single piece in a three-dimensional knitting process. The knitted upper includes at least one activated shrink yarn.

A knitted component including a first knit layer of a first yarn and a second knit layer of a second yarn. The second knit layer and the first knit layer are at least partially coextensive with each other and form a pocket between the first and second knit layers. A third yarn is at least partially positioned within the pocket and between the first and second knit layer. The third yarn is secured to the first knit layer at a first location within the pocket and to the second knit layer at a second location within the pocket. The pocket forms a raised structure when the knitted component is subjected to a stimulus.

A separable footwear article may comprise an outsole oriented at the bottom of the footwear and configured for ground contact, the outsole comprising a first material; an upper portion releasably coupled to the outsole with thread using chain stitching, the upper portion comprising a second material different from the first material; and an insole removeably disposed adjacent the upper portion and the outsole, the insole comprising a third material different from the first material and the second material; wherein the outsole, the upper portion, and insole are capable of being separated by releasing the thread and hand pulling the thread from the footwear article.

An upper may include a knitted component that at least partially forms a throat area of the upper. A first expandable yarn may be at least partially inlaid within a first course of the knitted component, the first expandable yarn having an inlaid portion that is between a first surface and a second surface of the knitted component, the first surface and the second surface including knitted loops of at least one course including a second yarn. The first expandable yarn may include an exposed portion that is exposed on the first surface of the knitted component. The inlaid portion of the first expandable yarn may have a first diameter, where the exposed portion of the first expandable yarn has a second diameter, and where the second diameter is larger than the first diameter.

A method of forming an upper for an article of footwear includes providing a first material layer over a shoe last, providing a second material layer over the first material layer such that the first and second material layers adhere to each other at an interface between the first and second material layers, where one or both of the first material layer and second material layer is provided by spray forming a polymer material onto the last. The material layers are removed from the last and turned inside out such that the first material layer includes an exposed surface that forms an exterior surface of the upper.

Hot melt sequins and methods of applying these sequins are disclosed. The sequins may be stitched to a layer of an article in a pattern to form a relatively rigid structure. The sequins may be made of a hotmelt material and melted to form a continuous structure. The sequins may be located along a lacing region and used as eyelets to secure laces.

A method of making an article of footwear with an upper including a ribbon structure is disclosed. The method includes laying down ribbon elements in straight and winding sections. The method includes stitching or otherwise attaching the ribbon elements to a backing layer. The method also includes embroidering a periphery of the ribbon structure to tack down any raised portions of the ribbon at the periphery. The method also includes inserting a lace through loops in the ribbon structure.

A method of forming an upper for an article of footwear includes providing a first material layer over a shoe last, providing a second material layer over the first material layer such that the first and second material layers adhere to each other at an interface between the first and second material layers, where one or both of the first material layer and second material layer is provided by spray forming a polymer material onto the last. The material layers are removed from the last and turned inside out such that the first material layer includes an exposed surface that forms an exterior surface of the upper.

An article comprised of tape segments embroidered in place is disclosed. One embodiment includes tape segments embroidered to a self-supporting embroidered structure. Another embodiment includes tape segments embroidered together to form an embroidered lattice structure. In one embodiment, some of the tape segments may expand when exposed to heat and may be used to form cushioning regions for the article.
