Abstract: A footwear closure system includes an article of footwear, such as a boot, having an upper portion, a lower portion, and a mid-portion that is positioned between the upper portion and the lower portion. The footwear closure system also includes a plurality of reel based closure devices that are coupled with the footwear. The plurality of reel based closure devices are configured to effect closure or tightening of the upper portion, the lower portion, and the mid-portion of the footwear. Each reel based closure device is independently operable and each reel based closure device effects closure or tightening of one of the upper portion, the lower portion, the mid-portion, or a combination thereof.

Abstract: A reel based closure device includes a housing component, a spool that is rotatably positioned within an interior region of the housing component, and a tightening component that is coupled with the housing component. The tightening component is operably coupled with the spool so that an operation of the tightening component causes the spool to rotate within the interior region of the housing component to wind a tension member about the spool. The housing component is configured so that the tension member is routed axially below the housing component's interior region and to one or more guides that are positioned along a lace path of an article, such as a shoe.

Abstract: Technology for generating geotemporal graphs is disclosed where geotemporal graphs provide representations of areas based on an expected travel time between points, instead of the geographical distance between points. Travel times may vary based on travel conditions, and geotemporal maps may be generated that show travel times that account for travel conditions. Generating geotemporal maps may include obtaining a graph, determining for several points a warp vector indicating graph how each point should be moved to represent a travel time to that point, and warping the graph according to the determined warp vectors.
