A last system and a method of making the last system are disclosed. The last system includes a last member and an exterior layer. The exterior layer becomes deformable when heated above a characteristic temperature. The method can include forming a braided footwear component on the last system. The exterior layer may be joined with the braided footwear component by heating the last system above the characteristic temperature.

An article of footwear comprises an upper and a sole structure secured to the upper. The upper includes a side portion that has a first material composition at an exterior surface of the side portion. The exterior surface has a first coefficient of friction. The sole structure has a second material composition at an exterior surface of the sole structure that underlies the side portion of the upper. The exterior surface of the sole structure has a second coefficient of friction. The first coefficient of friction is substantially equal to the second coefficient of friction.

Described are shoes, in particular a sports shoe, wherein at least a portion of an upper of the shoe includes a first layer and a functional second layer, wherein the functional second layer is directly printed onto the first layer.

An article of footwear includes a sole structure and an upper that is attached to the sole structure. The upper defines a cavity that is configured to receive a foot of a wearer. The upper is at least partially defined by a textile. The textile includes a first area that is substantially smooth. The first area defines a reference boundary that conforms to the cavity. The textile includes a second area. The second area includes a plurality of projection structures that project away from the reference boundary and outwardly from the cavity at varying heights. The second area includes a plurality of recess structures that recess away from the reference boundary and inwardly toward the cavity. The plurality of projection structures and the plurality of recess structures are in an alternating arrangement across the textile.

A footwear for wrapping an entire foot includes a t lain body made of foam rubber. The main body is dug to embed synthetic rubber into a heel side of a bottom of the min body made of the foam rubber. The embedded part is a part from a mid point from a toe to a heel to a heel part of the bottom of the main body. Specific gravities of the foam rubber and the synthetic rubber are 0.38 g/cm.sup.3 and 1.03 g/cm.sup.3, respectively. A center of gravity of the footwear is shifted to the heel side using a difference in the specific gravity of both to increase stability such that the footwear does not fall over when the footwear is placed upside down. An opening of the footwear is further formed to be flat with respect to a ground surface when the footwear is placed upside down.

An article of footwear may include an upper incorporating a knitted component. An inlaid strand extends through the knitted component. A combination feeder may be utilized to inlay the strand within the knitted component. As an example, the combination feeder may include a feeder arm that reciprocates between a retracted position and an extended position. In manufacturing the knitted component, the feeder inlays the strand when the feeder arm is in the extended position, and the strand is absent from the knitted component when the feeder arm is in the retracted position.

In one aspect, a textile component including bulking yarn is disclosed. In embodiments, the textile component is a knitted component. In one embodiment, an article of footwear includes a knitted component arch support configured to reduce the rate of pronation. A support structure may include a fusible yarn adjacent to an external surface of the arch support, a bulking yarn, and a nonfusible yarn. In certain embodiments, an arch support includes compartments and flex lines. In another aspect, an article having a knitted component includes a rigid material, a bulking yarn, and a flexible material. The rigid material may be fusible yarn. Methods for forming a textile component are provided. One embodiment involves knitting a first section comprising a fusible yarn, a second section comprising a bulking yarn, and a third section comprising a nonfusible yarn, and heating.

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)).

An upper includes an upper main body that covers an instep of a foot. The upper main body includes: a first portion including a plurality of linear bodies and formed by one layer; and a bag-shaped second portion formed by two layers in which some of the plurality of linear bodies constituting the first portion serve as one layer and the rest of the plurality of linear bodies serves as another layer. Inside the second portion, a cushioning material is put. The second portion protrudes toward a foot of a wearer with respect to the first portion.

The present invention relates to a shoe upper including a knitted component having a plurality of integrally knitted lines of loops including a set of consecutive lines, wherein each line in the set of consecutive lines includes a plurality of consecutive loops which are interlooped with adjacent loops of the respective line and not interlooped with loops of a line which is not contained in the set, and wherein the set of consecutive lines forms at least a portion of an eyelet which is configured to receive a lace.
