A sole structure for a footwear article includes a system of support structures. Each support structure includes a tubular body with an inwardly curving wall, which compresses under load to attenuate a force or impact and returns to a resting state when the load is removed.

Described are soccer shoes having an upper formed of knitwear, and a sole having cleats that are connected to the knitwear, wherein the knitwear is capable of coupling the sole to a foot of a wearer of the soccer shoe while the soccer shoe is being worn.

A breathable shoe, including an outsole arranged below a structural insert that is at least partially breathable, and below an upper. The outsole is at least partially breathable, including at least one sheet-like breathable element defined by a plurality of granules made of expanded material and having a uniform size, arranged in a substantially ordered manner and between which there are voids that form one or more channels through the breathable element that are permeable to air and/or vapor.

A sole structure including a first layer and a second layer is disclosed. The first layer includes a set of apertures arranged in an auxetic configuration that permits the first layer to exhibit a first auxetic behavior. The second layer includes a set of projections arranged in an auxetic configuration that permits the second layer to exhibit a second auxetic behavior. The first layer and the second layer may be joined together in a manner that allows the first auxetic behavior to occur independently of the second auxetic behavior.

Methods for preparing a footwear article are disclosed herein. An example method may comprise disposing resin adjacent a mold, disposing a lattice structure in at least a portion of the resin disposed adjacent the mold, closing the mold using a lasted upper, injecting foam into the closed mold such that the foam operates to couple the lasted upper and the lattice structure together.

A invention disclosed a bio-mimicked three-dimensional laminated structure at least comprising a flexible lattice structure, which is characterized in that the flexible lattice structure comprises a plurality of particle units are uniformly disposed and evenly distributed in the X-axis, the Y-axis, and the Z-axis direction and evenly distributed as a lattice matrix of an array grid in an identical plane; wherein each of the particle units is an opened hollow shell or a close shell. The design eliminates the need for support structures and the subsequent post-processing required to remove them. A shell-shaped close cell bio-mimicked three-dimensional laminated structure bio-mimicking a sea urchin shape was introduced for the load-bearing structure application.

An athletic footwear having an improved midsole that is having a double opposing helical network. The helical network can morph itself under compressive force.

A material that includes at least one layer made of an auxetic structure and articles of footwear having soles comprising the materials. When the material is under tension, it expands in both the direction under tension and in the direction orthogonal to the direction under tension. The articles of footwear have soles that have at least one layer made of a material that has a pattern of apertures to provide the auxetic structure. The apertures are surrounded by sole portions that can rotate or pivot to change the size of the apertures. An outer covering can be mated with an outsole structure formed by the auxetic structure. The outer covering includes features that mate with the apertures in the outsole structure. The outer covering is elastic and can stretch to accommodate expansion of the auxetic structure.

A footwear sole structure may include a plurality of discrete hexagonally-shaped sole elements defined by a plurality of sipes. The sipes may include a plurality of sipes that extend in a transverse direction across the sole structure and a plurality of sipes that extend in an oblique direction relative to the transverse sipes. A plurality of sipes may also subdivide the hexagonally-shaped sole elements into one or more diamond-shaped sole element portions. The sole structure may include additional features such as non-hexagonal sole elements and lugs distributed across a bottom surface of the sole structure.

An insulating shoe insert including a core layer formed of a cellular material, and a top layer and a bottom layer bonded to opposing sides of the core layer, respectively, the top layer and the bottom layer being configured as thin sheets of aromatic polyamide material such that the top layer and bottom layer cooperate with the core layer to create a heat transfer resistance sufficient to resist transfer of heat through the core layer.
