An article of footwear may have an upper and a sole structure secured to the upper. The sole structure has a plurality of support elements, and each of the support elements include a shell and a core. The shell defines an interior void and is formed from a polymer material that extends around substantially all of the void. The core has a shape of the void and is located within the void, with at least a portion of the core being a polymer foam material. The polymer foam material of at least two of the support elements may have different densities.

A tool path for treating a shoe upper may be generated to treat substantially only the surface of the shoe bounded by a bite line. The bite line may be defined to correspond to the junction of the shoe upper and a shoe bottom unit. Bite line data and three-dimensional profile data representing at least a portion of a surface of a shoe upper bounded by a bite line may be utilized in combination to generate a tool path for processing the surface of the upper, such as automated application of adhesive to the surface of a lasted upper bounded by a bite line.

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.

Manufacturing of a shoe is enhanced by creating 3-D models of shoe parts. For example, a laser beam may be projected onto a shoe-part surface, such that a projected laser line appears on the shoe part. An image of the projected laser line may be analyzed to determine coordinate information, which may be converted into geometric coordinate values usable to create a 3-D model of the shoe part. Once a 3-D model is known and is converted to a coordinate system recognized by shoe-manufacturing tools, certain manufacturing steps may be automated.

An adjustable jig for securing a textile during assembly. The textile may be an upper of an article of footwear. The jig includes a plurality of plates displaceable in a first axis and/or second axis, each plate with one or more pin attachment sites. A template is placed on the jig and pins are placed into each plate to set the pin pattern. The template is removed and a textile is mounted to the jig using the pin pattern. The jig may be configured to accommodate different sizes and shapes of textiles, and is resistant to heating and mechanical forces.

An article of footwear includes an upper with a knitted component formed of unitary knit construction. The knitted component has a first edge and a second edge. The knitted component also includes a base portion configured to be disposed adjacent the sole structure and to be disposed under a foot. The knitted component further includes a heel portion, a forefoot portion, a medial portion, and a lateral portion. The knitted component additionally includes a collar with a rim. The second edge is joined to the first edge at a seam. The seam has a first end and a second end, wherein the first end is located generally at the rim of the collar on one of the medial side and the lateral side of the upper. The second end is spaced from the first end.
