- Articles of footwear include different types of shoes, sandals, boots, heels, or the like. For the sake of clarity, articles of footwear will be discussed herein as shoes; however, embodiments are not limited solely to shoes. The technology disclosed herein may equally be used to create footwear other than shoes. To alleviate confusion and to provide a more readable disclosure, embodiments simply reference shoes. To that end and to provide a robust disclosure, different component portions of shoes are discussed herein, including uppers, midsoles, and outsoles. One skilled in the art will understand that shoes may include an upper and a sole structure, with the latter comprising an outsole, a midsole, and perhaps an insole.
- shoe 10 that includes a shoe sole 12 and a shoe upper 14.
- Shoe sole 12 may include a combination of an outsole and a midsole.
- shoe 10 includes a sole portion 16 that is removable. That is, sole portion 16 is positioned within shoe 10 in such a way that sole portion 16 may be taken out of shoe 10 and replaced by another sole portion.
- Sole portion 16 may be positioned within shoe 10 in various manners that would allow the selective removal and replacement of sole portion 16. For example, a cavity may be constructed in various portions of shoe 10 and sole portion 16 may be inserted into the cavity. The cavity may be accessible from various parts of the shoe 10 to place and to remove sole portion 16. Sole portion 16 may be inserted into a cavity or other recess, and sole portion 16 is also referred to herein as a "cartridge.” In addition, because sole portion 16 is often positioned in a middle region of sole 12, sole portion 16 may also be referred to herein as a "midsole portion" or “midsole cartridge”.
- the cavity may be positioned underneath an insole of the shoe, such that the insole covers an opening to the cavity.
- the insole may be temporarily removed or adjusted within the shoe to allow access to the opening.
- the midsole portion 16 may be placed or removed by accessing the cavity in this manner.
- the insole may be repositioned over the opening to cover the cavity and help retain midsole portion 16 in place.
- at least part of a stroble sock might be removed from the shoe 10.
- shoe sole 12 may include a cup outsole having walls (e.g., ground- striking wall coupled to perimeter side walls) surrounding a substantially hollow central portion.
- walls e.g., ground- striking wall coupled to perimeter side walls
- Midsole portion 16 may be positioned into the cavity, which functions as a housing for the midsole portion 16.
- the cavity may be accessible through a side wall of sole 12. That is, an opening may be constructed into a side of sole 12, such that midsole portion 16 may be slid into the cavity through the opening. Likewise, midsole portion 16 may be slid out of the cavity through the side- wall opening when replacing midsole portion 16.
- midsole portion 16 may attach onto an outside of sole 12. That is, midsole portion 16 may be shaped to clip onto a heel portion of sole 12 or may have some other configuration that allows midsole portion 16 to removably attach to sole 12.
- midsole portion 16 is depicted in a heel region 18 of shoe 10.
- a removable midsole portion may be positioned in other portions of the shoe.
- a single midsole portion may extend through both a heal region 18 of the shoe 10, as well as a toe region 20 of the shoe 10.
- multiple midsole portions might be simultaneously positioned in different regions of the shoe 10.
- one midsole portion might be positioned in the heel region 18, while a different midsole portion may be positioned inside a different cavity in the toe region 20.
- multiple midsole portions may be positioned within the same cavity or within cavities that are arranged side-by-side.
- one midsole portion may be positioned on one side of the shoe (e.g., left side, medial side, or instep side), whereas another midsole portion may be positioned on the other opposing side (e.g., right side, lateral side, etc.).
- midsole portion 16 may be viewable when inserted into the cavity.
- midsole portion 16 may be viewable from a side 22 of the shoe 10 or from a bottom 24 of the shoe 10.
- shoe sole 12 may enable the midsole portion 16 to be viewable.
- shoe sole 12 e.g., cup outsole
- shoe sole 12 may be constructed of a clear or transparent material through which midsole portion 16 may be viewed.
- shoe sole 12 may be constructed such that selected side-wall portions or bottom-wall portions include an aperture or viewing window, thereby allowing midsole portion 16 to be viewed.
- shoe sole 12 may include an opening in a side wall through which midsole portion 16 is inserted, and midsole portion 16 may be viewable through the side-wall opening.
- Midsole portion 16 may be constructed using various techniques that allow for creation of desired features, such as firmness, density, impact attenuation, shape, configuration, size, contour, color, etc. As such, midsole portion 16 may be constructed using more conventional techniques, such as molding (e.g., injection molding, blow molding, compression molding, vacuum molding, and the like), or may be constructed using less conventional techniques.
- molding e.g., injection molding, blow molding, compression molding, vacuum molding, and the like
- midsole portion 16 is constructed using a rapid-manufacturing technique.
- Typical rapid-manufacturing techniques build layers of the sole portion 16 in an additive manner, and exemplary techniques include a laser- sintering process, 3-D printing, stereolithography, solid deposition modeling, and the like.
- Rapid-manufacturing techniques such as laser sintering, allow for customization of desired features of midsole portions, such that a set of midsole portions may be built to be interchangeably inserted into a same shoe, thereby allowing the shoe to have a different appearance or functionality depending on which midsole portion is inserted.
- Laser sintering is an additive manufacturing technique that uses a laser (e.g., a carbon dioxide laser) to solidify small particles (e.g., powder) of plastic, metal, ceramic, or glass into a desired 3D shape.
- a laser e.g., a carbon dioxide laser
- the laser selectively fuses resin material determined from cross sections generated of a 3D digital description of the part— like a computer-aided design ("CAD") file, image file, or scan data file.
- CAD computer-aided design
- the laser is then directed to cure resin according to the 3D digital description until the desired component (e.g., a midsole portion)is created.
- a laser selectively fuses resin material by scanning cross sections generated from a data file or scan of a shoe on the surface of a resin bed. After each cross section is scanned, resin is dispersed, the laser cures the resin according to a cross section, and a new layer of resin is dispersed on top of the cured cross section. This iterative process is then repeated for all cross sections until the entire shoe or shoe part has been created.
- File data may be read and segmented into cross sections by a computer, server, or other computing device.
- sole portions 16 having a wide variety of functionality and design features.
- a rubber- or plastic-like material may be used that is rugged and can withstand contact with different surfaces.
- less-rugged type of rubber with blown-in air or hollo wed-out portions may be used to build a lighter sole portion 16.
- more malleable plastics may be used that are capable of forming around and holding onto other shoe parts, thereby holding a sole portion 16 in place within the cavity.
- Laser sintering can produce shoe parts from a relatively wide range of commercially available resins materials.
- resins materials include, without limitation, polymers, such as nylon (neat, glass-filled, or with other fillers) or polystyrene; metals, including steel, titanium, alloy mixtures, and composites; silica; elastomers and rubbers; latexes; or the like.
