A cushioning member for an article of footwear is provided and includes a first barrier member defining a first compartment and a second compartment and being formed from a first material. A second barrier member is attached to the first barrier member, covers the first compartment to define a first interior void, and covers the second compartment to define a second interior void. The second barrier is formed from a second material different than the first material. The cushioning member also includes a first quantity of particulate matter disposed within the first interior void and a second quantity of particulate matter disposed within the second interior void.

A shoe includes a sole having a midsole formed by a plurality of layer members laminated together, and an upper portion joined to the sole, The plurality of layer members of the midsole includes a cut having a linear shape, and a depth from a first height position to a second height position in a thickness direction.

A sole structure for an article of footwear having an upper includes an outsole, a plate disposed between the outsole and the upper, and a first cushioning layer. The plate includes an anterior-most point disposed in a forefoot region of the sole structure, a posterior-most point disposed closer to a heel region of the sole structure than the anterior-most point, and a concave portion extending between the anterior-most point and the posterior-most point. The concave portion includes a constant radius of curvature from the anterior-most point to a metarsophalangeal (MTP) point of the sole structure. The MTP point opposes the MTP joint of a foot during use. The first cushioning layer is disposed between the concave portion and the upper.

An article of footwear having a sole structure including a chamber for receiving a pressurized fluid is described, along with a method of making the article. The chamber may include a tensile member extending between a first chamber barrier layer and a second chamber barrier layer. The tensile member may include a first tensile member layer bonded to the first chamber barrier layer, a second tensile member layer bonded to the second chamber barrier layer, and a plurality of tethers connecting the first tensile member layer to the second tensile member layer. The second tensile member layer may include a first section and a second section separate from the first section. In addition, a portion of the second chamber barrier layer may extend toward the first tensile member layer between the first section and the second section, the portion being joined to the first tensile member layer.

A midsole for an article of footwear including a three dimensional mesh including interconnected unit cells and methods of making the same. The interconnected unit cells each include a plurality of struts defining a three dimensional shape. The interconnected unit cells are connected at nodes having a valence number defined by the number of struts connected at that node. The valence number of the nodes may vary to provide customized characteristics to zones or portions of the midsole. The plurality of interconnected unit cells may be organized in a warped cubic lattice structure. The warped cubic lattice structure and the size/shape of interconnected unit cells may vary to provide customized characteristics to zones or portions of the midsole. The three dimensional mesh may be customized based on a biometric data profile for an individual, or group of individuals. The midsole may be manufactured using an additive manufacturing process.

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 sole structure and shoes having the sole structure are provided which enable smooth cutting maneuvers or the like and stabilize a stacking state in the sole structure. An outsole has an elastic structure arranged between a base plate and a lower midsole portion in a thickness direction of a sole structure. The elastic structure includes a plurality of elastically deformable first columnar portions and at least one coupling portion for coupling the first columnar portions adjacent to each other. The elastic structure is configured such that the coupling portion couples second end portions of the first columnar portions adjacent to each other, and that the second end portions are connected, together with the coupling portion, to the lower midsole portion.

A sole structure for an article of footwear may include a chamber for receiving a pressurized fluid, the chamber having a first chamber barrier layer and a second chamber barrier layer bonded to the first chamber barrier layer about peripheral portions of the first chamber barrier layer and the second chamber barrier layer to define an interior void between the first chamber barrier layer and the second chamber barrier layer. The sole structure may also include a tensile member bonded to, and extending between, the first chamber barrier layer and the second chamber barrier layer. The sole structure may include a bond inhibiting material located between the tensile member and the first chamber barrier layer, the tensile member and the first chamber barrier layer being unbonded in an unbonded area in which the bond inhibiting material is disposed. The chamber may include an outwardly extending bulge in the unbonded area.

A sole structure includes a foam element extending from a forefoot region to a heel region. A lower surface of the foam element includes a recess formed in the forefoot region. The sole structure also includes a posterior cushioning arrangement extending along a peripheral region of the sole structure from a heel region to a mid-foot region, and an anterior cushioning arrangement disposed in the recess of the foam element. The anterior cushioning arrangement has a proximal end adjacent to the lower surface of the foam element and a distal end formed on an opposite side of the anterior cushioning arrangement than the proximal end. The anterior cushioning arrangement includes at least one medial bladder proximate to a medial side of the sole structure and at least one lateral bladder proximate to a lateral side of the sole structure.
