One or more aspects of the present disclosure provide optical element transfer structures that include an optical element releasably coupled with a transfer medium and methods of making and using the optical element transfer structures. The optical element transfer structures can be used to dispose an optical element onto an article, whereby the optical element imparts a structural color to the article.

One or more aspects of the present disclosure provide components for an article of manufacture, having a film with an optical element that imparts a structural color to the component. The present disclosure also provide methods for making components with the films and optical element, and articles of manufacture including the component.

One or more aspects of the present disclosure are directed to bladders that incorporate a multi-layer optical film that impart a structural color to the bladder. The present disclosure is also directed to articles including the bladders having a multi-layer optical film, and methods for making articles and bladders having a multi-layer optical film.

One or more aspects of the present disclosure are directed to bladders that incorporate a multi-layer optical film that impart a structural color to the bladder. The present disclosure is also directed to articles including the bladders having a multi-layer optical film, and methods for making articles and bladders having a multi-layer optical film.

One or more aspects of the present disclosure are directed to components having an optical element that imparts structural color to the component or article. The present disclosure is also directed to articles of manufacture including the component having an optical element, and methods for making components and articles having an optical element that imparts structural color.

One or more aspects of the present disclosure provide optical element transfer structures that include an optical element releasably coupled with a transfer medium and methods of making and using the optical element transfer structures. The optical element transfer structures can be used to dispose an optical element onto an article, whereby the optical element imparts a structural color to the article.

In example aspects, materials are repurposed for footwear manufacturing. That is, in some instances, materials in the footwear manufacturing supply chain are potentially subject to disposal. However, aspects of this disclosure sustainably repurpose those materials (that might otherwise be disposed of) to be used in footwear articles. In some aspects, the repurposed materials may be obscured with a concealing layer.

One or more aspects of the present disclosure are directed to bladders that incorporate a multi-layer optical film that impart a structural color to the bladder. The present disclosure is also directed to articles including the bladders having a multi-layer optical film, and methods for making articles and bladders having a multi-layer optical film.

Articles of footwear may include uppers having one or more skin layers attached to a base layer, wherein at least one of the skin layers is at least partially transparent or translucent. The transparent or translucent skin layer may be applied over other elements of the upper (e.g., other skin layers, base layers, reinforcing layers, etc.) to provide interesting color change options and color palettes for the upper. Additional aspects of this invention relate to production of curved tongue composite structures and/or footwear having a bonded (hot melt) side seam for forming the upper (and optionally do not include a rear heel seam).
