Abstract: An article of footwear includes a sole structure having a chassis and a bladder. The chassis includes a cavity and a plurality of pillars extending into the cavity. The bladder is disposed within the cavity and includes one or more chambers. Each of one or more chambers is supported by at least one of the pillars. The chassis may include a first plurality of the pillars extending from a first side of the cavity and a second plurality of the pillars extending towards the first plurality of the pillars from a second side of the cavity, whereby the bladder is supported between the first plurality of the pillars and the second plurality of the pillars. The one or more chambers of the bladder includes an interior chamber and a peripheral chamber at least partially surrounding the interior chamber and the peripheral chamber has a different pressure than the interior chamber.

Abstract: Aspects herein are directed to an upper, an article of footwear incorporating the same, and methods of forming the upper, where the upper includes a knit collar, a knit tongue tab that is integrally knit with the collar, and a knit heel tab that is integrally knit with the collar. At least a distal-most extent of the knit tongue tab extends away from a longitudinal midline reference plane of the upper toward a first side of the upper, and at least a distal-most extent of the knit heel tab extends away from the longitudinal midline reference plane of the upper toward a second side of the upper, where the second side is opposite the first side.

Abstract: A knitted component with a surface that includes first areas and second areas having different relative coefficient of frictions and that are formed in an alternating pattern. The first areas of the first surface are 40% to 80% of the total surface area for the first surface. The alternating pattern may be in the form of concentric shapes. The alternating pattern may have linear boundaries and curvilinear boundaries between first areas and second areas. The first areas can be formed from a first yarn having a core and a coating. The coating at least partially surrounds the core.
