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 and the medial edge of the tongue may be unsecured to the knit element. The tongue and the knit element may comprise a common yarn at least at the forward portion of the tongue.

Sole structures including a plate including a first polyolefin resin, and an edge portion comprising a second resin are disclosed herein. The edge portion is more flexible or less rigid than the plate. Articles of footwear formed from the sole structures are also provided. Methods of making the polyolefin resin compositions, plates, edge portions, sole structures, and articles of footwear are also provided. In some aspects, the first polyolefin resin composition includes an effective amount of a polymeric resin modifier.

Provided is, among other things, a shoe having a sole that includes multiple layers and an upper attached to and extending above the sole. In addition, the shoe includes a tab having: (1) a first portion, located between adjacent layers of the sole and thus hidden from view, that is imprinted with identification information pertaining to the shoe and (2) a second portion that is visible during ordinary use of the shoe.

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.

An upper may include a first knitted portion configured to form an outer surface of the upper, a second knitted portion configured to form an inner surface of the upper, where the second knitted portion is at least partially coextensive with the first knitted portion, an interstitial space between the first knitted portion and the second knitted portion, and a knitted connection structure connecting the first knitted portion to the second knitted portion. The knitted connection structure may extend at least partially along at least one of a tongue and a collar of the upper, and the second knitted portion may include at least one double jersey knit structure that is coextensive with the first knitted portion.

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.
