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 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 sole structure for an article of footwear having a heel region, a mid-foot region, a forefoot region, an interior region, and a peripheral region. The sole structure including a bladder having a chamber including an arcuate segment extending around the heel region, a first segment extending along the peripheral region on a medial side of the sole structure from the arcuate segment to a first terminal end in the forefoot region, and a second segment spaced apart from the first segment across a width of the sole structure and extending along the peripheral region on a lateral side of the sole structure from the arcuate segment to a second terminal end in the forefoot region. A peripheral outsole extends along the chamber and a first cushion is disposed between the first segment and the second segment and is exposed through an opening of the peripheral outsole.

A sole structure for an article of footwear includes a forefoot region disposed adjacent an anterior end, a heel region disposed adjacent a posterior end, and a mid-foot region disposed intermediate the forefoot region and the heel region. The sole structure further includes fluid-filled bladder having a first segment extending along a medial side in the heel region, a second segment extending along a lateral side in the heel region, and a web area disposed between the first segment and the second segment. Additionally, the sole structure includes an outer sole member having an upper portion extending from a first end in the forefoot region to a second end in the heel region. The second end of the outer sole member is received on a first side of the web area. The outer sole member also includes a rib extending downwardly from the upper portion and defining a cavity.

A fluid-filled chamber includes first subchamber having a substantially U-shape. The fluid-filled chamber also includes a second subchamber having a substantially U-shape and being spaced apart from the first subchamber in a direction extending along a longitudinal axis of the fluid-filled chamber.

The sole structure further includes fluid-filled bladder having a first segment extending along a medial side in the heel region, a second segment extending along a lateral side in the heel region, and a web area disposed between the first segment and the second segment. Additionally, the sole structure includes an outer sole member having an upper portion extending from a first end in the forefoot region to a second end in the heel region. The second end of the outer sole member is received on a first side of the web area. The outer sole member also includes a rib extending downwardly from the upper portion and defining a cavity.

The present invention is related to a shoe, the shoe including: a first outsole comprising a bottom portion which contacts the ground, and a plurality of first protruding portions each of which has a dome shape and protrudes upward from the bottom portion, and a second outsole comprising a support portion disposed on the bottom portion, and a plurality of second protruding portions each of which has a dome shape and protrudes downward from the support portion. Protruding end portions of the plurality of second protruding portions are bonded to protruding end portions of the plurality of first protruding portions, respectively.

A bladder for an article of footwear includes a first barrier layer formed of a first material, and a second barrier layer formed of a second material. The first barrier layer and the second barrier layer cooperate to form a fluid-filled chamber having a first fluid-filled segment extending along an arcuate path, a second fluid-filled segment extending from a first end of the first fluid-filled segment to a first distal end along a first longitudinal axis, and a third fluid-filled segment extending from a second end of the first fluid-filled segment to a second distal end along a second longitudinal axis parallel to the first longitudinal axis. The first barrier layer and the second barrier layer may be joined together define a web area connecting each of the first segment, the second segment, and the third segment.

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.
