Shoe uppers having smooth seams and methods for producing them are disclosed. In one embodiment the upper uses thermoplastic seam tape which forms bonds between contiguous upper sections after being subjected to heat and/or pressure. In another embodiment, different parts of the shoe can be joined using hidden seams. Close seams can also be covered with a transfer material adapted to give the interior and/or exterior of the upper a smooth surface. In yet another embodiment, a method is disclosed which allows three-dimensional upper sections to be bonded on a last using thermoplastic seam tape.

A footwear article is provided herein. The footwear article may include a sole coupled to a cord structure. The cord structure may include interconnected bights in a vamp cord and a rand cord forming a loop line extending along at least a portion of the footwear article.

Embodiments of the present invention relate to a shoe construction that includes an upper that has an interior surface and a corrugated exterior surface of rapid manufactured material. The upper interior surface and corrugated exterior surface form a lattice-interlace surface. The lattice-interlace surface includes the interior surface that has a plurality of horizontal laths, the corrugated exterior that has a plurality of vertical laths, and a plurality of lattice apertures that extend from an interior of the shoe to an exterior of the shoe. The shoe construction further includes an interior sole portion of sintered material. The interior sole portion forms a tessellated framework. The tessellated framework includes a lattice of hollow cubes; each hollow cube has a top surface opening and a bottom surface opening, the openings extending from an interior of the shoe to an exterior of the shoe.

The footwear includes a base having a toe portion, a heel portion opposing the toe portion, a base left and right side, and a bottom surface to engage the ground when worn by a user. The footwear additionally includes a base top surface opposing the base bottom surface, a toe box permanently coupled to the toe portion of the base at the top surface, and a counter permanently coupled to the heel portion of the base at the top surface. The footwear further includes a left and right support structure permanently coupled to the top surface of the base between the toe box and the counter on each side of the base, and a detachable left and right panel configured to detachably connect to the respective left and right support structure.

An article of footwear with a dynamic support system that controls arrays of tiles in the upper of the footwear to adjust the level of support provided in different regions of the upper. Sensors in the sole of the footwear, in the upper of the footwear and/or in an article worn by the wearer of the footwear measure the level of stress or other characteristics and provide input to one or more microprocessors that control motors located in the sole or in the upper of the footwear. When the motors are activated, they may compress or loosen arrays of tiles to adjust the stiffness of the upper in one or more regions of the upper.

A sole structure for an article of footwear includes a first midsole body and a second midsole body. The first midsole body defines a ground-facing surface and a foot-facing surface opposite the ground-facing surface and includes a first midsole material, which has a first hardness. The second midsole body extends through the first midsole body. As such, the second midsole body extends beyond the ground-facing surface of the first midsole body. The second midsole body includes a second midsole material, which has a second hardness, and the first hardness is greater than the second hardness.

An upper may include a first knitted portion configured to form an outer surface of the upper, a second knitted portion configured to form an inner surface of the upper, where the second knitted portion is at least partially coextensive with the first knitted portion, an interstitial space between the first knitted portion and the second knitted portion, and a knitted connection structure connecting the first knitted portion to the second knitted portion. The knitted connection structure may extend at least partially along at least one of a tongue and a collar of the upper, and the second knitted portion may include at least one double jersey knit structure that is coextensive with the first knitted portion.

A rapid-entry shoe having a heel arm configured to transition between a collapsed configuration, for easy donning and doffing of the shoe, and an uncollapsed configuration, for securing a foot inside the shoe, the shoe having a resilient member configured to bias the heel arm toward the uncollapsed configuration.

Foot support systems (and articles of footwear including them) include a midfoot flex component, such as a bi-stable spring element, that moves the article of footwear/sole structure/foot support component/midfoot flex component between an open position/foot insertion or removal configuration and a closed position/foot supporting configuration and vice versa.

An article of footwear includes an upper and a closure mechanism. The upper has an opening at least partially located between a first and second portions of the upper. The opening is adjustable between open and closed configurations. The closure mechanism is moveable between unlocked and locked positions and includes a locking element coupled to the first portion of the upper and a projection coupled to the second portion of the upper. The projection is moveable in a first direction relative to the locking element to engage with the locking element, thereby moving the closure mechanism to the locked position and moving the upper to the closed configuration. The projection is moveable in the first direction relative to the locking element to disengage with the locking element, thereby moving the closure mechanism to the unlocked position and allowing the upper to return to the open configuration.
