An upper of an article of footwear comprises a plurality of stretch zones each having a respective stretching capability. Suitable example stretch zones may include four-way stretch zones, two-way stretch zones, and/or lock-out zones. In some examples, an upper having a plurality of stretch zones comprises a single continuous piece of material configured to have regions of different stretching capability. The single piece of material may comprise a layered material having two stretchable outer layers, wherein a plurality of stretch zones of the piece of material are defined by corresponding intermediate layers disposed at selected locations between the outer layers. Examples of intermediate layers providing two-way stretch, four-way stretch, and little or no stretch are disclosed.

A bladder for an article of footwear includes a first barrier layer, a second barrier layer coupled to the first barrier layer at a peripheral seam, a chamber defined between the first barrier layer and the second barrier layer and defining an interior void, and a knit infill material disposed within the interior void of the chamber between the first barrier layer and the second barrier layer and including a first material and a second material, the first material comprising a fusible yarn.

A method of manufacturing a multicolor-foamed shoe body by supercritical foaming includes step S1 to step S3: step S1: provide a plurality of cold shot model molds and inject a plurality of foaming materials in different colors into a cavity of each of the cold shot model molds to form a plurality of cold shot models in different colors that is unfoamed; step S2: place the cold shot models in a hot-pressing mold for hot pressing to make a contacting surface of any two of the cold shot models that are adjacent engage with each other due to heating to foam a semi-finished product; and step S3: place the semi-finished product in a supercritical foaming autoclave for foam molding to obtain the multicolor-foamed shoe body. Additionally, the multicolor-foamed shoe body manufactured by the method is also disclosed in the present invention.
