Abstract: A sole structure for an article of footwear includes a heel region, a forefoot region, a fluid-filled chamber and a midsole. The fluid-filled chamber extends from the heel region to the forefoot region. The midsole includes a first projection contacting the fluid-filled chamber at a first contact region in the forefoot region and a second projection contacting the fluid-filled chamber at a second contact region in the heel region. The first projection is spaced apart and separated from the second projection to define a gap.

Abstract: A cushioning structure includes an externally-reinforced bladder, the bladder having a first polymeric sheet and a second polymeric sheet, where each polymeric sheet includes an internal surface and an opposite external surface. A first reinforcing layer is in contact with the external surface of the first polymeric sheet, where the first reinforcing layer has a greater modulus than the first polymeric sheet. A second reinforcing layer is in contact with the external surface of the second polymeric sheet, where the second reinforcing layer has a greater modulus than the second polymeric sheet. The bladder includes an internal volume and a peripheral flange surrounding the internal volume, and the reinforcing layers are only secured to the polymeric sheets at the peripheral flange.

Abstract: A sole structure for an article of footwear includes a fluid filled bladder that is formed from a plurality of coextensive, stacked polymeric sheets. An anti-weld material is disposed between two of the polymeric sheets within a central region of the sheets, the anti-weld material operative to inhibit a first polymeric sheet from being able to thermally fuse with a second polymeric sheet wherever the anti-weld material is present. The first polymeric sheet and the second polymeric sheet are fused together in a peripheral region that surrounds the central region, the peripheral region forming a peripheral flange. At least one of the first polymeric sheet and second polymeric sheet includes a plurality of integrated reinforcing fibers that are operative to increase a modulus of elasticity of the sheet in a direction parallel to the reinforcing fibers.
