As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The surface of the article can include the optical element with sections that have different relative thicknesses from one another. A first section imparts a first structural color and a second section imparts a second structural color. The first structural color and the second structural color differ from each other when viewed from the same angle of observation from a viewer having 20/20 visual acuity and normal color vision from a distance of about 1 meter from the article including the optical element.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article includes the optical element including one or more layers. The surface of the article can include the optical element with regions that impart different structural colors. The different structural colors imparted are due at least in part to the different structure (e.g., cross-sectional structure) of the optical element in certain regions.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article includes the optical element on its surface and the optical element includes one or more layers (e.g., a reflective layer(s), a constituent layer(s), and the like). The optical element can include a plurality of different sections, where each of the different sections have a different relative thickness.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article includes the optical element including one or more layers. The surface of the article can include the optical element with regions that impart different structural colors. The different structural colors imparted are due at least in part to the different structure (e.g., transverse cross-sectional structure) of the optical element in certain regions.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article can include an optical element including one or more layers. The surface of the article can include the optical element with regions that impart different structural colors. The different structural colors imparted are due at least in part to the different structure (e.g., transverse cross-sectional structure) of the optical element in certain regions.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The article can include the optical element (e.g., a single layer reflector, a single layer filter, a multilayer reflector or a multilayer filter) including one or more layers (e.g., a reflective layer(s), a constituent layer(s), and the like). The surface of the article can include areas of the surface that are at different relative heights from one another and can impart different structural colors.

As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The present disclosure provides for articles (e.g., structurally colored articles) that exhibit different structural colors in different regions of the article using an optical element, where the optical element has different structures (e.g., cross-sectional structures) in at least two of those regions.

Fastening devices and systems and methods thereof. Fastening devices and systems and methods thereof can include a unitary or one-piece body having first and second ends configured and operative to be coupled together or to be coupled to their respective complement in another of said fastening devices. The first end can include a ring or annular portion and a projection that are sized and shaped to fit around an anchor and in an orifice, respectively, of the second end. Fastening devices and systems and methods thereof according to embodiments may be used with items, including footwear, apparel, luggage, a backpack, a bag, a purse, a boxing glove, a punching bag, football or lacrosse shoulder pads, or the like.

The present invention provides an item of footwear. It is desired to provide an item of footwear (100) which provides an attractive appearance whilst maintaining the comfort of the user. It is particularly advantageous to deliver a thinner item of footwear (100), which still maintains the comfort of a thicker item. An item of footwear (100) comprises a securing means for securing the item of footwear (100) to a foot of a user; and a sole for engaging a foot of a user in use, the sole having a heel region (20) for supporting the heel of a wearer in use and a forward region (30) for supporting the forefoot of a wearer in use, wherein: the sole (1) has a raised protrusion (22) forming the upper surface (2) in a first portion of the heel region (20).

A shoe system includes a sole and a shoe upper connected with the sole. A gap is disposed between a first upper portion and a second upper portion. The shoe system also includes a first permanent connector permanently connected to the first upper portion; a second permanent connector permanently connected to the second upper portion, and a removable and printable connector strap connectable with the shoe upper. First and second releasable connector portions of the removable and printable connector strap are releasably connectable with the first and second permanent connectors, respectively.
