A shoe sole includes a resilient member, and has a bottom surface as a ground contact surface and a top surface. The resilient member has a three-dimensional shape formed by a wall having an outer shape defined by a pair of parallel flat or curved surfaces, and may buckle when the resilient member receives a compressive stress applied in a normal direction to the bottom surface. In the shoe sole, when a load is applied to the shoe sole in a gradually increasing manner such that a compressive stress is applied to the resilient member in the normal direction, the resilient member starts to buckle when a stress applied to the resilient member is within a range of 0.05 MPa or more and 0.55 MPa or less and a strain of the resilient member in the normal direction is within a range of 10% or more and 60% or less.

A method of manufacturing a component for a sole structure of an article of footwear includes providing a printer having a platform, a first head that receives a first feed, and a second head that receives a second feed. The method further includes printing a base layer on the platform, with the base layer comprising a substrate material and defining a longitudinal axis. Additionally, the method includes printing a first fiber layer continuously on the base layer, with the first fiber layer defining a first fiber orientation that is disposed at a first angle relative to the longitudinal axis, and printing a second fiber layer continuously on the first fiber layer, the second fiber layer defining a second fiber orientation that is disposed at a second angle relative to the longitudinal axis. The first angle is different from the second angle.

A sole structure for an article of footwear may have a midsole system that includes a sole plate having a forefoot region and a midfoot region. The sole plate may have a foot-facing surface and a ground-facing surface opposite to the foot-facing surface. The sole plate may define a through hole extending from the foot-facing surface to the ground-facing surface in the forefoot region. The through hole may be closer to a medial edge of the sole plate than to a lateral edge of the sole plate. The sole plate may have ridges extending longitudinally in the midfoot region and in the forefoot region. The ridges may have crests at least some of which may extend non-parallel with one another in a longitudinal direction of the sole plate.

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.

The invention relates to an item of footwear in which is provided a mid-sole (10) with features that provide comfort to the wearer when walking. An item of footwear comprising: a sole (1) comprising a mid-sole (10), the mid-sole having a first major surface (11) for facing the foot of a wearer, a second major surface (12) opposite the first, the mid-sole (10) having an inner edge (13) corresponding to the inside of a wearer's foot and an outer edge (14) corresponding to the outside of a wearer's foot; and a securing means for securing the item of footwear to a foot of a wearer such that the first surface (11) of the sole (1) contacts the foot, wherein: the mid-sole (10) has formed therein a plurality of generally transverse grooves (20) and a generally longitudinal primary groove (30a), thereby dividing the sole (1) into an array of lands (50); and the primary groove (30a) is substantially parallel to the outer edge (14) of the sole (1) over a majority of the length of the sole (1) and defines with 15 the transverse grooves (20) a plurality of lands (50).

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.
