This invention relates generally to footwear and methods for making the same, more particularly to a seamless upper for footwear and methods for making a seamless upper. In one aspect of the invention, the upper is seamless and/or is of unitary construction that defines an interior void for comfortably receiving a foot.

An article of footwear and a method of manufacturing the article of footwear are disclosed. The footwear may include an upper and a sole structure. The upper incorporates a textile element with edges that are joined together to define at least a portion of a void for receiving a foot. The textile element may also have a first area and a second area with a unitary construction. The first area is formed of a first stitch configuration, and the second area is formed of a second stitch configuration that is different from the first stitch configuration to impart varying textures to a surface of the textile element. Various warp knitting or weft knitting processes may be utilized to form the textile element.

The invention is an upper for an article of footwear that includes a textile having fusible filaments or fibers. The textile is incorporated into the upper and specific areas of the upper are heated such that the fusible filaments or fibers fuse with other filaments or fibers to form fused areas. In comparison with unfused areas of the upper, the fused areas may impart properties that include greater stretch-resistance, stability, support, abrasion-resistance, durability, and stiffness, for example. In addition, the fused areas generally provide air-permeability without significantly increasing the weight of the footwear.

A combination of sensors, including solid-state gyros and force-sensitive resistors, are mounted in an insole suitable for insertion into a shoe. Data from the sensors is recorded by an in situ Programmable Interface Controller (PIC), logged into on-board EEPROM/Flash memory and relayed to a base station computer via a miniature telemetry transmitter triggered by RFID tagging. Software then uses this data to compute the cadence and ankle power of the subject, as well as other parameters, in order to analyze and assess the gait and activity of the subject.

In addition, receivers may include communications components which may allow for communication to various electronic equipment including transmitters.

An article of footwear is disclosed that includes at least one of a stretchable upper and an articulated sole structure. The upper may include an exterior layer and an interior layer. The exterior layer forms at least a portion of an exterior of the upper, and the exterior layer includes a plurality of incisions that extend through the exterior layer. The interior layer is located adjacent an inner surface of the exterior layer, and the interior layer is exposed through the incisions. The sole structure may include a connecting portion and a plurality of discrete sole elements. The connecting portion is positioned adjacent the upper and may extend along a longitudinal length of the upper. The sole elements extend from the connecting portion, and the sole elements are separated by a plurality of sipes that extend upward into the sole structure.

There is disclosed an inflatable lining for selected inner surfaces of footwear, such as a shoe, boot or sandal. The inflatable lining is formed of first and second plastic sheets having the shape and size of the selected inner surfaces, e.g., a sole, or any portion of the upper surfaces of the footwear. The sheets are bonded together in a continuous seam about their peripheral edges thereby forming a sealed interior chamber. A plurality of discontinuous seams are formed between the first and second sheets to create within the sealed interior chamber a plurality of interconnecting tubular passageways, and at least one continuous seam can also be provided that subdivides the interior chamber into two or more subdivided interior chambers. The inflatable liner is provided with an air pump that preferably is a flexible bulb with an inlet valve which discharges into a flexible tube which extends to a pressure control valve and then to the interior chamber of the inflatable inner sole. Preferably the flexible bulb is mounted at the heel of the inner sole. The pressure relief valve is manually adjustable to control the pressure within the inflatable inner sole. Excess air from the pressure control valve can be directed into channels formed on the undersurface of the inner sole where it discharges through sealed apertures in the inner sole thereby providing forced air circulation in the footwear. Alternatively, manually operated air pumps can be provided.

An article of footwear includes an upper member and a sole structure, with a sensor system connected to the sole structure. The sensor system includes a plurality of sensors that are configured for detecting forces exerted by a user's foot on the sensor. Each sensor includes two electrodes that are in communication with a force sensitive resistive material. Additionally, the sensor system may be provided on an insert that may form a sole member of the article of footwear. The insert may include an airflow system that includes one or more air chambers in communication with one or more air reservoirs through air passages extending therebetween. The insert may also have a multi-layered structure, with the airflow system provided between the layers.

A shoe sole is composed of particles of Ethylene Vinyl Acetate and the particles are connected with each other with gaps defined between the particles so as to form irregular surface of the shoe sole. The sole is made by filling the particles to 77% to 87% of volume of a cavity in a mold set, wherein an angle 40 to 50 degrees is clamped between a spinning axis of the cavity and an axis to which the mold set is rotated about. The mold set is then heated to 140 to 160 degrees Celsius and spins the mold set about the spinning axis 22 to 32 minutes. After cooling the mold set, the shoe sole is formed and is removed from the cavity.

A disposable shoe liner that is formed from a first substrate, a second substrate, and discrete regions of a functional material sandwiched therebetween is provided. In particular, the first and second substrates contain are fused together at certain portions such that fused portions and unfused portions are formed. The unfused portions form pockets that contain the functional material. In some embodiments, for example, the pockets contain activated carbon granules to provide comfort to the foot and to absorb odors exuded therefrom.

An insole providing cushioning and control of foot motion. The insole includes a stability cradle and a number of pods on the underside of the insole core or base. Some of the pods have different material properties selected to help control foot motion.

A shoe footbed 10 made by first molding a shape-retaining layer 12 into a contoured condition. After the shape-retaining layer 12 has been molded, a layer of thermal insulation 14 is placed on top of the molded layer 12. A conforming layer 16 and a fabric top layer 18 may be placed over the thermal insulation 14 and the shape-retaining layer 12. The inventive method of manufacture is particularly suited for making insulated footbeds that contain nonwoven webs of polymeric microfiber because damage to the fibrous web from heat and compression may be avoided.

The present invention teaches a method of making a custom article of footwear. Further, the article of footwear can include a spring element that can provide improved cushioning, stability, and running economy.
