An article of footwear, method, and motorized lacing system includes a motor, including a motor shaft, a spool, coupled to the motor shaft, configured to spool and unspool the lace based on the turning of the motor shaft, a processor circuit, and a three-dimensional encoder. The three-dimensional encoder defines a major axis and has a surface having a tabs extending from a drum, an optical sensor, positioned within optical range of the cylindrical encoder, configured to output a signal to the processor circuit indicative of a detected one of the tabs, and a beam break, positioned between the three-dimensional encoder and the optical sensor, forming a pair of slits. The optical sensor is positioned to view the tabs through the pair of slits, wherein the processor circuit is configured to operate the motor based, at least in part, on the signal as received from the optical sensor.

A shoe including an upper, a sole including slots formed in a bottom of the sole, and retention overlay. The sole is removably attached to the shoe upper via the retention overlay, which is provided within the slots formed in the bottom of the sole.

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.

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 restraining device configured to inhibit the removal of an article of footwear to which the restraining device is attached is provided. The restraining device will prevent footwear from being removed regardless of the type of fastening means used to secure the footwear to the foot of a wearer and whether the fastening means are fastened. In some embodiments, the restraining device is configured to be permanently attached to an article of footwear. In other embodiments, the restraining device is configured to be removably attached to an article of footwear. In some embodiments, the restraining device generally includes a ring-shaped member, a tightening means, and a locking mechanism. In other embodiments, the restraining device generally includes a restraining strap and a unique locking mechanism.
