An example method may comprise determining, based at least on one or more images, one or more areas of wear indicative of worn portions of an article such as an article of footwear. The example method may comprise mapping the one or more areas of wear to a two dimensional wear model. The example method may comprise determining, based at least on the one or more images, a severity of wear of one or more of the one or more areas of wear. The example method may comprise determining, based on the two dimensional wear model and the severity of wear of each of the one or more areas of wear, a pattern for a custom article. The example method may comprise outputting a machine-readable code representing the pattern. The machine-readable code may be configured to be processed by a machine to cause manufacture of at least a portion of the custom article.

A skate (e.g., an ice skate) or other footwear for a user, in which a skate boot or other foot-receiving structure for receiving a foot of the user may be configured to enhance power transfer of the user (e.g., for push-off and skating straight), agility of the user (e.g., for turns), and/or other aspects of performance of the user, such as by comprising a sole region that is configured to be disposed under the user's foot and includes different materials strategically distributed (e.g., in a longitudinal direction of the skate boot or other foot-receiving structure) or otherwise implements these enhancements.

A skate includes a skate boot with two opposed boot side portions extending from heel and ankle portions to a forward edge of the boot side portions. A forward-most eyelet is the eyelet closest to the forward edge. A toe cap is connected to the skate boot at a front end, and the toe cap has toe cap side portions extending rearwardly to a rear edge of the toe cap disposed forward of the forward-most eyelet. A toe cap extension extends rearwardly from the rear edge of the toe cap and over a portion of the boot side portions defined rearward of the forward edge and below the forward-most eyelet. The toe cap extension engages the portion of the skate boot and allows movement of at least the skate boot rearward of the forward-most eyelet during formation of the skate boot or use thereof.

A skate boot comprising an outer shell including medial and lateral side portions for facing the medial and lateral sides of the foot. Each of the medial and lateral side portions has an upper edge. The skate boot also comprises a lace member mounted to either of the upper edges of the medial and lateral side portions. The lace member has at least one opening for receiving an insert. The lace member has a first flexion mode when no insert is received in the at least one opening and a second flexion mode when the insert is received in the at least one opening. The second flexion mode is different from the first flexion mode.

A skate assembly includes a shell structure and a removable tendon guard. The shell structure includes a heel portion, a lateral ankle portion, and a medial ankle portion. The heel portion is formed to cover a human heel. The lateral ankle portion is formed to extend beyond the heel portion. The medial ankle portion is formed to extend beyond the heel portion. The lateral ankle portion and the medial ankle portion are spaced apart to form a notch extending toward the heel portion. The removable tendon guard is removably attached between the lateral ankle portion and medial ankle portion to cover the notch.

A liner for a skate boot that includes an outer surface and an inner surface. The outer surface is configured to be mounted to a shell of the skate boot. The inner surface includes a first material and an overlay of a second material covering a part of the first material. The overlay and another part of the first material not covered by the second material are configured to be exposed to a foot when the foot is placed in the skate boot.

A tongue for a skate boot includes a body having a first segment and a second segment at a lower end. One or both of the first and second segments are displaceable toward the other to a sandwiched position. The first and second segments overlap in the sandwiched position and position part of a toe portion of the boot between the first and second segments. The first segment includes two mating tabs spaced apart from each other, and the second segment includes two segment apertures spaced apart from each other. In the sandwiched position, the first segment engages an inner surface of the part of the toe portion and the second segment engages an outer surface, two toe portion apertures are aligned with the two segment apertures; and the two mating tabs pass into the two toe portion apertures and into the two segment apertures.

A shoe includes: a heel portion; a toe portion; a sole portion; and an electrical assembly. The electrical assembly includes at least: a magnetometer configured to determine a direction of movement of the shoe; and an accelerometer configured to determine acceleration of the shoe. Direction and acceleration data are used to generate a display of a map indicating traversal of a route by a wearer of the shoe at user interface of a user device.
