Footwear uppers include a footwear upper base formed from one or more component parts and including: (i) an instep region including at least one of a tongue base region or instep base region and (ii) a heel-containing region. A bladder is engaged with the footwear upper. The bladder includes: (i) at least a first instep chamber engaged with the instep region, (ii) at least a first heel and/or ankle support chamber engaged with the heel-containing region, and (iii) a first fluid line connecting the first instep chamber and the first heel and/or ankle support chamber and placing the first instep chamber in fluid communication with the first heel and/or ankle support chamber. Fluid moving from the first instep chamber to the first heel and/or ankle support chamber (e.g., under force applied by a footwear securing strap) provides further support for the wearer's heel and/or ankle.

A fluid-filled chamber, which may be incorporated into articles of footwear and other products, may include an outer barrier and a tensile element. The outer barrier may have a first portion, an opposite second portion, and an interior surface defining an interior void. The tensile element may be secured to the first portion of the outer barrier in a plurality of first bond areas and may be secured to the second portion of the outer barrier in a plurality of second bond areas. Each of the bond areas may be connected to portions of the tensile element spaced from the interior surface.

A device configured to surround a portion of a foot-receiving cavity at a heel region of an article of footwear comprises a control bar having a center segment, a first side arm extending from the center segment, and a second side arm spaced from the first side arm and extending from the center segment. The control bar may include a series of slats. A base supports the control bar and is connected to the first side arm and the second side arm. The control bar is biased to an unstressed position with the center segment a first distance from the base, and elastically bends under an applied force to a loaded position with the center segment a second distance from the base less than the first distance. The device stores potential energy that returns the control bar to the unloaded position upon removal of the applied load.

A shock absorption shoe, having a sole and at least one shock absorption module each having an outer shell, an inner core, an air cushion cylinder and a bottom cover, and each being connected to an air tube. The inner core is sleeved into a cavity of the outer shell from the top. A position limiting structure is provided between the inner core and the cavity. The air cushion cylinder is sleeved within the cavity. The bottom cover covers the bottom of the cavity. The shoe has a bottom layer, a middle layer and a top layer; the middle layer contains at least one mounting hole for mounting the at least one shock absorption module. The air tube is in an air tube groove on the middle layer, and one end of which is connected to the air cushion cylinder while another end is connected with a nozzle.

A sole structure for an article of footwear having an upper includes a heel region, a forefoot region, and a mid-foot region disposed between the heel region and the forefoot region. The sole structure also includes a bladder including a first barrier layer cooperating with a second barrier layer to define a first chamber bounding a periphery of the heel region, and a second chamber extending from the mid-foot region through the forefoot region and including a plurality of segments extending from a medial side of the sole structure to a lateral side of the sole structure. Each of the segments of the second chamber includes a medial reservoir adjacent to the medial side and a lateral reservoir adjacent to the lateral side, the medial reservoir fluidly coupled to the lateral reservoir via a first conduit.

A footwear sole structure having a fluid-filled chamber including a tensile member is provided. The fluid-filled chamber includes a first barrier sheet, a second barrier sheet and the tensile member. The first barrier sheet is formed from a first thermoplastic material. The second barrier sheet is attached to the first barrier sheet and is formed from a second thermoplastic material. The first barrier sheet and the second barrier sheet cooperate to define an internal cavity. The tensile member is disposed within the internal cavity and is formed from a third thermoplastic material. A first weld attaches the first barrier sheet, the second barrier sheet, and the tensile member together by melding the first thermoplastic material of the first barrier sheet, the second thermoplastic material of second barrier sheet, and the third thermoplastic material of the tensile member.
