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 sensor system includes an airbag engaged with the sole structure of an article of footwear, the airbag configured to compress and expand during use of the article of footwear, a force sensor engaged with the airbag and configured to detect force on the airbag based on changes in capacitance as the airbag compresses and expands, a port connected to the article of footwear and configured for communication with an electronic module, and one or more conductive leads extending from the force sensor to the port to place the force sensor in communication with the port. The system may be used with an article of footwear including an upper member at least partially defining a foot-receiving chamber and a sole structure engaged with the upper member.

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: Sole structures for articles of footwear, including athletic footwear, include: (a) an outsole component; (b) a midsole component engaged with the outsole component, wherein the midsole component includes at least one opening or receptacle; (c) at least one fluid-filled bladder system or foam system provided in the opening or receptacle; and/or (d) a rigid plate system including one or more rigid plates overlaying the fluid-filled bladder or foam system(s). The rigid plate(s) may be fixed directly to the midsole component or the rigid plate(s) may rest on the fluid-filled bladder(s) or foam somewhat above the surface of the midsole component when the sole structure is in an uncompressed condition. Articles of footwear and methods of making sole structures and articles of footwear including such sole structures also are described.

Abstract: Shoes and/or shoe elements facilitate natural foot motion and/or reduce forces tending to fight natural foot motion. In at least some such structures, a wearer's heel is secured to the hindfoot region of a shoe (e.g., by a strap system) in a manner that permits heel/forefoot rotation and that allows the lower leg to remain straight. In other structures, a shoe can include a heel supporting component that is separate from a midsole component, and this heel supporting component can move toward the lateral side and/or medial side of the shoe along an interface between the heel supporting component and the midsole component. Other suitable shoe and shoe component structures also are described.

Abstract: Various sensor systems are described herein, including inserts having sensors thereon, which are configured to be received in an article of footwear. The inserts may be connected to a sole member of the footwear, or may function as a sole member. The sensors may be bonded to an outer surface of the insert, or positioned within the insert, in some configurations. The system may also include an electronic module that is overmolded into the sole structure and includes a connector for external access.

Abstract: Strap systems for securing feet into articles of footwear or other foot-receiving devices include one or more strap members formed or engaged together in a continuous path along an upper for an article of footwear or other foot-receiving device. One or more structures for applying a force to the strap member(s) is provided so as to shorten a length of the continuous path and thereby apply tension to the strap member(s). Such strap systems can be arranged so that the strap tightens during plantar flexion or dorsiflexion. Additional aspects of this invention relate to bootie members for supporting such strap systems, upper members or bootie members including such strap systems, and articles of footwear and other foot-receiving devices including such strap systems.

Abstract: A shoe can include support members for a plantar surface of a foot that include: (a) a heel support plate; (b) a forefoot support plate; (c) a heel securing strap component for securely engaging a heel supporting component with a wearer's heel; and (d) a unidirectional hinge, wherein the hinge allows the heel support plate to rotate internally with respect to the forefoot support plate and limit the heel support plate from rotating externally with respect to the forefoot support plate. The support member allows the shoe to twist and move with the foot, allowing the ankle to remain neutral, rather than the shoe fighting the foot's natural motion. The unidirectional nature of the hinge plate also prevents the shoe from rotating externally beyond a predetermined limit point.
