摘要:
A bladder assembly for an athletic shoe and having at least first and second chambers. The chambers are independently and separately pressure adjustable by the user to conform to different concavity areas of his foot, such as the arch, ankle and metatarsal areas, to thereby enhance fit, comfort and athletic performance. Both chambers are inflatable by the same articulated on-board pump and deflatable by the same on-board depressible plunger. A dial on the lateral side of the upper allows the user to select which of the chambers is to be pressure adjusted, that is, which of the chambers is in pressure communication with the pump and the plunger. When the dial is in a neutral position, accidental inflation or deflation of either chamber is prevented.
摘要:
A complex-contoured tensile bladder and method of making same in which a bladder comprises an envelope formed from two outer barrier layers surrounding a tensile element formed of two inner sheets. The inner sheets are attached to one another along selected first attachment portions and include die cuts at certain locations. Each of the outer barrier layers are attached to the inner sheet nearest it at selected second attachment portions which are incoincident with the selected first attachment portions. The outer layers are sealed around the periphery to form the envelope and the bladder is inflated with a gas so that the inner sheets form a tensile member which extends between the selected second portions, and the selected first portions form hinges disposed between the outer layers. When loaded the tensile member compresses at the hinges which readily allow for compression while not interfering with the cushioning properties of the gas. This construction of the bladder allows for the formation of complex-curved, contoured shapes by appropriately selecting the first attachment portions and the second attachment portions and the die cuts.
摘要:
A bladder which is particularly useful for a sole assembly of a shoe is formed of multiple layers of barrier film to provide multiple pressurized layers of cushioning fluid or gas when the bladder is filled. A multiple gas layer bladder enhances cushioning response by relying more on the response characteristics of the gas and reducing the amount of foam and the dependence on foam as a cushioning material. The internal film layers provide a truss-like geometry in cross section and act as tensile members to impart a generally smooth surface contour to the bladder. The bladder is constructed to provide complex regionalized cushioning profiles which are coupled to the anatomy of the foot and expected loads at known points.

摘要:
A shoe having a closure system is disclosed. The shoe has an upper and a sole attached to the upper. A first strap member is attached to the medial side of the shoe at two longitudinal locations. A second strap member is attached to the lateral side of the shoe at two longitudinal locations. A first adjusting member is slidably coupled to both the first and second strap members. The first adjusting member is slidable along the first and second strap members towards the front of the foot to tighten the upper about the forefoot of the foot. A second strap member is slidably coupled to both the first and second strap members. The second adjusting member is slidable along the first and second strap members toward the rear of the foot to tighten the upper about the ankle and heel of the foot.
摘要:
Impact-attenuation members include body portions, optionally with an arched structure, that define a base orientation and an open space; and a spring member extending across the open space and engaging the body portion(s). When a force is applied to the body portion(s) in at least some orientations and/or directions of incident force, e.g., so as to change the impact-attenuation member out of its base orientation, the spring member may exert a force that urges the impact-attenuation member back toward the base orientation. Various example structures for the impact-attenuation member are described. Such impact-attenuation members may be used in articles of footwear or other foot-receiving device products.

An article of footwear includes a tongue. The tongue includes a medial portion, a lateral portion, a central portion, a top portion and an upper perimeter portion. The medial portion and the top portion have similar thicknesses, which are greater than the thicknesses of the lateral portion, the central portion and the upper perimeter portion. The central portion is the thinnest portion of the tongue. Each portion of the tongue corresponds to a different pressure zone along a foot in order to provide differential cushioning and support against pressure applied by a fastening system.

An article of footwear includes a tongue. The tongue includes a medial portion, a lateral portion, a central portion, a top portion and an upper perimeter portion. The lateral portion, the central portion and the upper perimeter portion include holes. The top portion and medial portion are substantially solid portions without holes. Each portion of the tongue corresponds to a different pressure zone along a foot in order to provide differential cushioning and support against pressure applied by a fastening system.
摘要:
An impact attenuating device includes both concave and convex side walls, e.g., in an interleaved arrangement, optionally at least partially surrounded by a restraining element that may help return the impact attenuating device back to its original orientation after attenuating an impact. Such impact attenuating devices may be included in pieces of footwear and/or other foot-receiving devices. Additionally, such impact attenuating devices or portions thereof may be freely selected and/or interchanged in a piece of footwear or other foot-receiving device, e.g., based on one or more characteristics of an intended user and/or an intended use, so as to allow users to obtain footwear (or other devices) customized and targeted for use under a predetermined set of conditions.
