A charging system can include provisions for providing power to various systems or components associated with the article of footwear. A charging system may include a charging unit with one or more components configured for use with one or more articles of footwear, where the articles of footwear can include different sizes. The components can be magnetically joined to the article in some cases. Upon connection with a power source, the article may be configured to unlace automatically. In some cases, the charging system can be used to facilitate the transfer of power to components in an automated tensioning system.

An article such as an article of footwear includes a lacing system having two laces that are routed through lace-receiving passages in two distinct zones of a body of the article. A first lace can be routed through a first set of lace-receiving passages in a first zone, and a second lace can be routed through a second set of lace-receiving passages in a second zone. A method of lacing an article includes routing the first lace and the second lace through the lace-receiving passages of the respective zones.

Lacing engine systems, apparatus, and methods of operation are discussed. In an example, a lacing engine apparatus can include a housing, a drivetrain, and a lace take-up mechanism for retracting a length of lace cable upon activation. The drivetrain can include various reduction gears to reduce rotational speed out of the motor and power the lace take-up mechanism. The lace take-up mechanism can include structures such as a double-yoke, a radial pulley including an outer rotating disc and an inner stationary disc, a variable take-up spool, or a zip-strip mechanism.

A worm drive fit system is provided, including a yoke member and a drive assembly, the drive assembly including a dial housing having an exterior and interior surface, wherein the interior surface includes a dial gear in operable engagement with a pinion gear. The drive assembly further includes a worm gear in operable engagement with the pinion gear, a spool gear in operable engagement with the worm gear, and a spool attached to the spool gear, wherein the spool is rotatably mounted to the yoke and configured to receive a filament to be tightened around the spool.

Systems and apparatus related to automated tightening of a footwear platform including a footwear lacing apparatus are discussed. In an example, a footwear lacing apparatus can include a housing structure, a spool, and a drive mechanism. The housing structure can include a top section and a bottom section. The spool can include a superior surface, a lace spool under the superior surface and a spool shaft with a keyed connection pin. The spool can also be integrated into the top section of the housing structure. The drive mechanism can couple with the spool via the keyed connection pin on the spool shaft. The drive mechanism can be adapted to rotate the spool to tighten or loosen a lace cable integrated into the footwear.

An article of footwear includes an upper that has a body extending over at least a portion of a first side and a second side of the upper. A laceless fastening system includes a strap having an anchored end fixed at the second side and a distal end selectively remote from the upper. A first fastener is fixed to an outer surface of the body on the first side. The first fastener is less elastic than the body. A segmented second fastener is fixed to the inner side of the strap. The segmented second fastener includes a proximal segment and a distal segment closer to the distal end of the strap than the proximal segment and spaced apart from the proximal segment along the strap by an exposed portion of the strap. The segmented second fastener is less elastic than the strap.

A tensioning system for articles of footwear (100) and articles of apparel is disclosed. The tensioning system includes a tensioning member that is tightened or loosened using a motorized tensioning device for winding and unwinding the tensioning member on a spool. The motorized tensioning device includes a torque transmitting system that allows for incremental tightening, incremental loosening and full loosening of the tensioning member.
