A shoe having an upper and a sole connected to the upper. The upper has, at least in part, a knitted material forming its outer surface. To ensure sufficient longitudinal elasticity in the forefoot region and a good fit, along with efficient production, the knitted material consists of a first knitted material layer produced from a first thread, wherein the first material layer has arranged on it a second knitted material layer produced from a second thread. The second material layer at least partially covers the first material layer. In the region of the front half, as seen in the longitudinal direction of the shoe, and/or in the heel region of the shoe, the second material layer runs, at least in part, in strip form in a direction transverse to the longitudinal direction of the shoe so as to form a number of strips running parallel to one another.

A shoe that grows comprises a sole having a toe, medial side, lateral side, and heel. The toe of the sole extends outwardly to form a toe cap. A vamp member is adjustably connected to a free end of the toe cap. At least one medial strap connects the vamp member to the medial side of the sole. At least one lateral strap connects the vamp member to the lateral side of the sole. An adjustable heel strap connects to the medial and lateral sides of the sole and extends around the heel of the sole.

A flexible shoe includes an under sole, a foot bed, a first over-foot portion, and a second over-foot portion. The under sole is formed of ballistic nylon. The foot bed is arranged on an upper surface of the under sole. The first over-foot portion is attached to the under sole and is configured to flexibly overly an instep of a foot of a user forward of an ankle of the user. The second over-foot portion is configured to flexibly wrap around a heel of the user rearward of the ankle of the user and includes a tab extending toward and coupled a heel portion of the under sole. The under sole, the first over-foot portion, and the second over-foot portion define a cavity configured to enclose the foot of the user. The foot bed is positioned entirely within the cavity.

Systems and methods for automatically producing a cord structure are provided herein. In one embodiment, a method comprises automatically forming, with at least one robotic arm, a first plurality of loops in a first plane, and automatically forming, with the at least one robotic arm, a second plurality of loops in a second plane orthogonal to the first plane, the second plurality of loops slippably engaged with the first plurality of loops. In this way, cord structures may be quickly constructed, thereby reducing labor input and expense.

Textile Components, such as upper members for articles of footwear, include: (a) a first portion having a first edge, wherein the first edge includes a first portion of material engaged with a first seam support material via a first thermoplastic material; (b) a second portion having a second edge, wherein the second edge includes a second portion of material engaged with a second seam support material via a second thermoplastic material; and (c) structure to engage the first and second edges in an abutting edge joint (such as a zig-zag stitch). The resulting textile components may be lightweight and breathable (e.g., due to use of lightweight upper fabric), having a comfortable fit (e.g., due to the abutting edge joint), while still providing a strong, stable, and durable construction (e.g., due to the presence of the seam support member(s)).

A sole structure for an article of footwear comprises a unitary midsole having a first portion and a second portion rearward of the first portion. A bottom surface of the unitary midsole defines a groove extending from a medial side to a lateral side of the unitary midsole, and a top surface of the unitary midsole defines a slit disposed over the groove and extending from the medial side to the lateral side. The unitary midsole forms a living hinge at the groove and the slit, with the living hinge connecting the first portion to the second portion so that the first portion and the second portion are selectively pivotable relative to one another at the living hinge between a first orientation and a second orientation. The groove is wider in the first orientation than in the second orientation, and the slit is wider in the second orientation.

A shoe with a sole, upper, and shaft, whose upper and shaft contain a number of modifications to increase flexibility of the shoe but maintain protection for the wearer of the shoe. These modifications fall into the general categories of notch and aperture. The upper also has a number of protrusions into the shaft to increase protection in the protrusion areas. The location, shape, and size of these notches, apertures, and protrusions are important for optimizing the flexibility and protective qualities of the shoe.

An upper for an article of footwear may have a knitted component, where the knitted component has a first edge extending from a first side of a throat area of the upper, through a heel area of the upper, and to a second side of the throat area. At least a portion of the first edge may include a lattice structure, the lattice structuring having a first lattice band and a second lattice band, the first lattice band and the second lattice band having loops that are intermeshed in at least one location, where a plurality of first openings are located between the first lattice band and the second lattice band. At least one of the lattice bands may include a yarn having a tenacity of at least 5 g/d, and/or the first and second lattice bands may be formed from separate yarns.

Methods for manufacturing articles of footwear including forming a first upper on a textile manufacturing machine and forming a second upper on the textile manufacturing machine at a time that at least partially overlaps with formation of the first upper. The first upper and the second upper are formed at separate locations of the textile manufacturing machine.

Shoe having a transversal air passageway comprising a shoe sole (4) and an upper (1) and a lower (3) pliable parts for enclosing a foot of the user of the shoe, wherein the shoe further comprises a peripheral band (2) formed in the shape of a closed line and formed in a resilient material, wherein the upper and lower parts are attached by their outer edges to opposing faces of said peripheral band along its length, and wherein the lower part is attached to the shoe sole in both the front and back parts of the shoe, but not in a part between the front and back parts of the shoe, such that a transversal air passageway (5) is formed from the medial part to the lateral part of the shoe, between the front and the back parts of the shoe, and between the shoe sole and the lower part.
