This disclosure concerns a master model for the production of a mold, comprising: (a) a first part, a second part comprising a textured surface; wherein the first part and the second part are connected.

An article of footwear includes an upper and a sole. The upper includes an attachment region and a bottom portion that is bounded by the attachment region. The sole defines a concave inner surface. The concave inner surface includes a peripheral surface region and a central surface region. The attachment region of the upper is attached to the peripheral surface region of the sole. The bottom portion is held in tension over the central surface region.

An article of footwear may include an outer member comprising a first ground engaging member extending substantially downward from the outer surface of an outer member. Ground engaging members may be auxetic structures that can increase their dimensions in a direction that is orthogonal to the direction of applied force or tension. The outer member may have a substantially uniform thickness. Ground engaging member shapes may include various polygonal features. The first ground engaging member may have a substantially three-pointed star-shaped pyramidal structure. The first ground engaging member may have three arm portions, a central region, a central tip, and an apex. The outer member may have an inner surface with apertures that correspond with the ground engaging members of the outer surface.

An article of footwear including a sole system, including an upper and the sole system. The sole system includes a knitted component incorporating a one-piece knit outsole. The knit outsole has a ground-facing side, a top side, and a ground-engaging cleat member protruding from the ground-facing side of the knit outsole. The upper is connected at its bottom to the top side of the knit outsole.

An article of footwear can include a tensioning system with a multilayered upper and a relatively narrow strobel. One layer of the upper can be attached to an outer periphery of the strobel. Another layer of the upper can be attached to a portion of the sole structure. In addition, a lacing region can be formed by folding a laminated structure including the second layer. A third layer of the upper can provide a bootie within the article of footwear configured to receive a foot.

A footwear component that includes a sole including a recessed area and a support member positioned in the recessed area. The support member includes a main support, a front support that extends at least partially over a front end of the main support, and a rear support that extends at least partially below a rear end of the main support. The front support of the support member moves toward the main support when pressure is applied to the front support and moves away from the main support when pressure is released from the front support. Similarly, the rear support of the support member moves toward the main support when pressure is applied to the rear support and moves away from the main support when pressure is released from the rear support.

An article of footwear includes an upper and a sole structure with a sole member. The sole member can be manufactured using a system that modifies the heel cushioning of the sole member over a series of footwear purchases. The modifications can be configured to correspond to a customer's evaluation of the heel cushioning previously purchased. The sole member can include a set of apertures that are formed along various surfaces of the sole member to adjust the cushioning characteristics of the sole member.

A sole structure can include provisions for improving the cushioning characteristics and stability of an article of footwear. The sole structure may include multiple layers with specialized structural properties designed to integrate regions of stiffness with cushioning layers. In some cases, the sole structure can include at least two independent stability layers that differ in stiffness.
