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: 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: An article of footwear includes an upper and a sole assembly that is operably coupled to the upper. The sole assembly includes a first portion and a second portion that are separated by a groove. Also, the article of footwear includes a biasing structure that is elongate and nonextendable. The biasing structure is operably coupled to the sole assembly to bias the first and second portions of the sole assembly generally toward each other.

Abstract: A method and system that allows for large amounts of data to be printed utilizing a small memory is provided. The complete image to be printed on the print medium is separated into different regions each having associated print data. The memory device, while being too small to store all of the print data for the full image, is capable of storing the print data associated with each region. The print data for each region is released from the print head controller to the memory device for printing in a timed fashion based on movement of the print medium. The print data for a subsequent region will not be passed to the memory until the print medium has moved a sufficient distance, thereby indicating that printing of the preceding region has been completed.

Abstract: An article of footwear includes an upper and a sole assembly secured to the upper. The sole assembly has an upper plate and a lower plate in a forefoot portion of the sole assembly, and a plurality of lower plate arms curving downwardly from the upper plate.

Abstract: Methods and systems relating to an ankle and foot support system are disclosed. Some embodiments may include a covering having a cable tightening mechanism and a cable forming an exposed loop. The exposed loop may be attached to a loop receiving member located on the covering. The exposed loop may also be attached to a footwear loop anchor located on an article of footwear. In some embodiments, the covering may include more than one exposed loop for attaching to more than one loop receiving member located on the covering, as well as more than one footwear loop anchor located on an article of footwear. In some embodiments, adjusting the cable tightening mechanism may secure the covering to the article of footwear.

Abstract: Methods and systems relating to an ankle and foot support system are disclosed. In some embodiments, a covering having a cable tightening mechanism may be associated with a cable that is slidably engaged with the cover. In some embodiments, the cable may be slidably engaged with a tube guide that is attached to the cover. In some embodiments, the cable may form an exposed loop that associates with a loop receiving member. In some embodiments, the loop receiving member may be attached to the cover.

Abstract: An article of footwear includes first and second midsole layers and first and second outsole layers. The second midsole layer defines a plurality of bores. A first outsole layer is translucent. A second outsole layer includes a plurality of non-contiguous abrasion-resistant members that correspond in shape and size to one or more of the bores in the second midsole layer.

Abstract: A tightening system for an article of footwear includes a cable disposed between an upper and a sole plate. The upper includes a flexible main body and an exoskeleton covering a portion of the flexible main body in an instep region. The cable is attached to the exoskeleton so that the exoskeleton is tightened to a wearer's foot when the cable length is effectively shortened and/or if the cable tension is increased. The instep region is devoid of the tightening system so that a smooth instep region is provided.

Abstract: A heel cup formed from a flexible material is located under the heel region of an upper portion of an article of footwear. Lateral and medial counters extend upward from the heel cup on the lateral and medial sides, with the medial counter having a height less than that of the lateral counter, and with a rear edge of the heel cup being lower than the lateral and medial counters. A rear strap extends upward around the lateral counter and around the Achilles tendon of the wearer, and is secured to a location on the upper that is forward of the wearer's ankle. During cutting movements in which the article is worn on the outside foot, tilting of the wearer foot and ankle toward the medial side pulls the strap and causes the lateral counter to conform to and support the wearer heel.

Abstract: An article of footwear including heel portion movable relative to the forefoot portion from a first articulated configuration to a second articulated configuration is provided. An articulation assembly having a forefoot articulation member and a heel articulation member is also provided. The articulation assembly couples the forefoot portion to the heel portion and includes a hinge mechanism and a cam mechanism. The hinge mechanism may include a pin located within a socket. The cam mechanism may include a cam surface and a protrusion configured to ride on the cam surface. The article of footwear may include a locking mechanism having a first locking element that engages a second locking element in the first articulated configuration. The first locking element may be a first concavity formed in a surface and the second locking element may be a protrusion configured to extend into the first concavity in the first articulated configuration.

Abstract: An article of footwear has an upper and a sole structure. The upper has a foot portion for receiving a foot and a leg portion for receiving at least a portion of a leg, and the sole structure is secured to a lower area of the foot portion. The footwear includes at least one of a plate system, a hinge system, and a sole structure formed from materials of different hardness, stiffness, or density.

Abstract: Engaging elements may be included in foot-receiving devices, such as footwear, bindings, clips, or the like. Such elements may include a bimodal spring member movable between two independent stable positions and an arm that moves in response to the bimodal spring member changing between its stable positions. The engaging elements additionally may include a retaining element extending from the arm and/or an arm/bimodal spring interface that induces changes in position of the arm in response to the bimodal spring member changing its stable position. The bimodal spring member, the arm, the retaining element, and/or the arm/bimodal spring interface may form an integral unit. Additionally, methods of engaging a foot-receiving device with a user's foot are disclosed.
