A shoe, in particular a running shoe, may include an upper and a sole unit. The upper is attached to the sole unit such that in a midfoot region there is a gap between a lower side of the upper and a top side of the sole unit. The gap may extend from a lateral side of the shoe to a medial side of the shoe.

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.

A sole for an article of footwear includes a continuous dispensed component forming a first layer and a second layer. The first layer is disposed directly on top of the second layer. The continuous dispensed component forms a medial sidewall and a lateral sidewall. The first layer includes a starting point where the continuous dispensed component is first dispensed. The continuous dispensed component continuously transitions from the first layer to the second layer at the starting point.

A method and apparatus for printing onto a curved surface of an article are disclosed. An embodiment of a method may include receiving the article and extruding a composite yarn from a nozzle. A method may include attaching the composite yarn to the curved surface by moving the nozzle in a direction aligned with a first axis and a direction aligned with second axis along the curved surface. The first axis may be approximately normal to the print surface and the second axis may be approximately normal to the first direction. The article may be repositioned during printing to accommodate nozzle movement.

The present disclosure provides an upper for an article of footwear. The upper may include a knit element defining a portion of at least one of an exterior surface of the upper and an opposite interior surface of the upper. The interior surface may define a void. A tongue and the knit element may have a common yarn, and the tongue may extend through a throat area of the upper. The tongue may comprise a lateral edge, a medial edge, and a forward portion. At least one of the lateral edge, the medial edge, and the forward portion may be unsecured to the knit element. The tongue may be secured to the knit element at least at one of the lateral edge, the medial edge, and the forward portion of the throat area.
