One or more aspects of the present disclosure provide articles of manufacture and components of articles that incorporate an optical element that imparts a structural color to the component or the article. The component comprises a thermoplastic polymeric material, and can include or be made to have a textured surface.

An article of footwear may include an upper and a sole structure secured to the upper. The article of footwear may further include an accessory system that includes at least one ornamentation selectively securable to and removable from one or both of the upper or the sole structure. The one or more ornamentations may partially cover a contoured outer surface of the upper when secured to one or both of the upper or the sole structure but may be relatively flat when not secured to the upper or the sole structure. An accessory kit and a method of manufacturing the article of footwear includes securing first fastener components to the upper or sole structure and providing ornamentations with second fastener components releasably securable to the first fastener components and arranged in the same spatial arrangement when so secured.

An article of footwear has a tubular structure. The tubular structure may include tab portions that extend away from a tunnel portion of the tubular structure. The tab portions may engage parts of the article of footwear. The tab portions may engage an upper or sole structure along a bite line. The tab portions may be attached to a heel counter, eyestay, or other structure on the article of footwear.

An ornament stud for an article is provided. The stud includes: a head having a three-dimensional shape; a plurality of shoulders extending horizontally and inwardly from an edge of the head by a predetermined length; and a plurality of sharpened extensions extending respectively and vertically from inner edges of the plurality of shoulders, the plurality of sharpened extensions being spaced from each other along the inner edges of the plurality of shoulders by a predetermined distance.

The present disclosure provides for articles that can exhibit structural colors through the use of an optical stack and a cover release layer, where the cover release layer is disposed on an externally (or outwardly) facing surface of the optical stack. The optical stack can be disposed on a substrate, which can be disposed on a surface of an article or the optical stack can be disposed on a surface of the article. The cover release layer can be disposed on the optical stack on the side opposite the substrate or article surface so it is on the externally facing surface and can be viewed by an observer. When exposed to visible light, the optical stack imparts a structural color, where the structural color is visible color produced, at least in part, through optical effects (e.g., through scattering, refraction, reflection, interference, and/or diffraction of visible wavelengths of light). The structural color can have a single color or be multicolor, including iridescent. The cover release layer is disposed over (e.g., at least portions) of the optical stack so that the structural color is not present since it is not exposed to light, but when the cover release layer is removed, the optical stack can impart structural color. The cover release layer can be removed by abrasion (e.g., intentional or unintentional), where the abrasion can be applied to the cover release layer that causes separation of the cover release layer from the optical stack.
