Abstract:
An article of footwear may incorporate a chamber with an outer barrier and a tether element. The barrier may be formed from a polymer material that defines an interior cavity, and tether element may be located within the interior cavity and joined to opposite sides of the barrier. Upon pressurization of the chamber, the tether element may extend across the interior cavity and be placed in tension by the outward force of a pressurized fluid within the interior cavity. The tether element may have a variety of configurations. For example, the tether element may have a diagonal orientation, or different tether elements may have different lengths. A tether element may also have plates or tie pieces secured to opposite sides of the chamber, with one or more tethers extending between. Also, the tether element may include one of more sheets that extend across the interior cavity.

Abstract:
An article of footwear includes an upper, a sole attached to the upper, and an impact absorber attached to the upper at least along a midfoot region of the upper and capable of absorbing a portion of a lateral impact when the impact absorber is moved into contact with a top surface of the sole. The impact absorber is be integrally formed with the sole and has a width that varies along a length of the impact absorber. The width of the impact absorber decreases in a forefoot region and a heel region. The upper rolls to contact the top surface of the sole upon lateral impact. The sole and the upper may be attached asymmetrically.
Abstract:
A material that includes at least one layer made of an auxetic structure and articles of footwear having soles comprising the materials. When the material is under tension, it expands in both the direction under tension and in the directional orthogonal to the direction under tension. The articles of footwear have soles that have at least one layer made of a material that has a pattern of apertures to provide the auxetic structure. The apertures are surrounded by sole portions that can rotate or pivot to change the size of the apertures.
Abstract:
A steaming system for an article of footwear includes a container with a lid configured to accommodate a steam source. The system also includes provisions for securing the article of footwear such that a majority of the upper is subjected to steam. Articles of footwear may be placed in the steaming system to help customize the articles of apparel for a user's fit and comfort. The steaming system can be configured to be portable and carried by a person.
Abstract:
Various arrangements for an article of footwear including an outsole having grooves forming discrete lugs are presented. The outsoles generally include a plurality of grooves formed in at least a portion of the outsole that extend from a lateral side of the outsole to a medial side of the outsole. The grooves may be linear or curved and generally extend in an angular fashion. The grooves may have a first depth at a perimeter of the outsole and a second depth, greater than the first depth, at the center of the outsole. The grooves form discrete lugs. In some arrangements, the lugs are diamond shaped.
Abstract:
A shoe has a sensor system operably connected to a communication port. Performance data is collected by the system and can be transferred for further use via the communication port. The shoe may contain an electronic module configured to gather data from the sensors. The module may also transmit the data to an external device for further processing. Users can use the collected data for a variety of different uses or applications.
Abstract:
A material that includes at least one layer made of an auxetic structure and articles of footwear having soles comprising the materials. When the material is under tension, it expands in both the direction under tension and in the direction orthogonal to the direction under tension. The articles of footwear have soles that have at least one layer made of a material that has a pattern of apertures to provide the auxetic structure. The apertures are surrounded by sole portions that can rotate or pivot to change the size of the apertures. An outer covering can be mated with an outsole structure formed by the auxetic structure. The outer covering includes features that mate with the apertures in the outsole structure. The outer covering is elastic and can stretch to accommodate expansion of the auxetic structure.
Abstract:
A tensile strand element for an article of footwear is disclosed. The tensile strand element includes one or more tensile strands secured at their endpoints between the sole and upper of an article of footwear, creating one or more looped portions. The unsecured looped portions may extend into the fastening region of the footwear and engage with a fastening system to tighten the footwear upper snugly against a wearer's foot to provide added support.
Abstract:
An article of footwear or other product may include a material element having a first layer, a second layer, a third layer, and at least one strand. The second layer is positioned between the first layer and the third layer, and the second layer is formed from a thermoplastic polymer material. The strand is located between the first layer and the second layer, and the strand lies substantially parallel to the second layer for a distance of at least five centimeters. In this configuration, the thermoplastic polymer material may join the first layer and the third layer to the second layer. The thermoplastic polymer material may also join the strand to the second layer.
