An article of footwear including an upper and a sole assembly secured to the upper and including a support assembly having an upper member and a lower member spaced from the upper member. A first layer is positioned beneath and in contact with the upper member and has a wave shaped profile with a plurality of first wave crests and first wave troughs. A second layer is positioned above the lower member and has a wave shaped profile with a plurality of second wave crests and second wave troughs.

An article of footwear has a midsole assembly that includes a fluid-filled bladder element having a substantially arc-shaped heel portion and having a lateral arm portion and a medial arm portion spaced from the lateral arm portion. Each of the arm portions extend from the heel portion. The bladder element is configured to be positioned with the heel portion in the heel region of midsole assembly, and the arm portions extending from the heel region to a forefoot region along a peripheral region. A method of manufacturing and a mold assembly for such an article of footwear are provided.

A sole, particularly for shoes, includes a plantar-like perimetric shape and is constituted by a plurality of layers which has at least one supporting structure, for plantar support, which is elastic and on an upper surface of which there is at least one seat for at least one mid-sole.

The mid-sole is constituted by a body from the lower surface of which a first plurality and a second plurality of elastically compressible protrusions protrude downward, each one having an axial cavity.

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 fluid-filled chamber including a first barrier layer cooperating with a second barrier layer to define a fluid-filled segment extending along a medial side of the sole structure within the heel region, a second fluid-filled segment extending along a lateral side of the sole structure within the heel region, and a web area disposed between and connecting the first fluid-filled segment and the second fluid-filled segment. The first barrier layer is attached to the second barrier layer within the web area.

An article of footwear includes a strobel, a footwear upper, and a sole plate. The strobel includes a polymeric bladder defining an interior cavity and configured to retain a fluid in the interior cavity. The polymeric bladder has a peripheral flange extending around a perimeter of the interior cavity from a medial side to a lateral side of the polymeric bladder at a front of the polymeric bladder. The footwear upper is secured to the peripheral flange. The sole plate has a heel portion, a midfoot portion, and a forefoot portion, and a rear extent of the strobel is secured to the sole plate or to the footwear upper forward of a rear extent of the sole plate. A method of manufacturing the article of footwear includes securing the peripheral flange to the upper.

A sole structure for an article of footwear comprises a midsole including a first cushioning layer, a second cushioning layer, and a third cushioning layer. The first cushioning layer has a central portion, and a peripheral portion surrounding the central portion. The first cushioning layer, the second cushioning layer, and the third cushioning layer are stacked with the second cushioning layer directly overlying the peripheral portion of the first cushioning layer, and the third cushioning layer overlying the second cushioning layer and directly overlying the central portion of the first cushioning layer. The first cushioning layer has a domed lower surface extending away from the second cushioning layer and the third cushioning layer and substantially centered under the central portion.

A shoe sole is basically provided with a first layer and a second layer. The second layer is coupled to the first layer. The second layer has a forefoot part and a tarsal part. The forefoot part extends along the first layer and the tarsal part is configured to be displaceable relative to the first layer.

A support structure for a shoe sole includes a support piece with elasticity, the support piece is provided at the forefoot or/and arch position of the shoe sole and is laid out along the width direction of the shoe sole, the support piece is provided with a number of raised arc sections or/and concave arc sections along the width direction of the shoe sole. Shoe soles and athletic shoes include the support structure described above, the shoe sole support structure bonded or integrally molded to the upper surface of the shoe midsole, or bonded or integrally molded between the shoe midsole and the shoe outsole, or embedded inside the shoe midsole.

A sole structure for an article of footwear is provided. The sole structure includes an outsole having a ground-engaging surface and an upper surface formed on an opposite side of the outsole than the ground-engaging surface. A first cushion is disposed proximate to a medial side of the sole structure and includes a first fluid-filled chamber attached to the upper surface of the outsole and a second fluid-filled chamber attached to the first fluid-filled chamber and disposed between the first fluid-filled chamber and the upper. A second cushion is disposed proximate to a lateral side of the sole structure and includes a third fluid-filled chamber attached to the upper surface of the outsole and a fourth fluid-filled chamber attached to the third fluid-filled chamber and disposed between the third fluid-filled chamber and the upper. The second cushion is fluidly isolated from the first cushion.

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.
