Disclosed is a tielayer composition having an epoxy-containing compound, a polythiol curing agent, a curing catalyst, and a solvent present in an amount of at least 25% by weight, based on the total weight of the tielayer composition. Also disclosed is a tielayer comprising the tielayer composition in a cured state. Also disclosed is a coated substrate. The substrate has at least one coatable surface and a tielayer formed from the tielayer composition applied to at least one surface of the substrate and cured thereon. The substrate may be footwear. Also disclosed is a method for forming a bond between two substrates.

Presented are footwear sole structures with foot-cushioning insoles movably mounted onto impact-attenuating midsoles, methods for making/using such sole structures, and footwear fabricated with such sole structures. A multilayered sole structure assembly includes an insole movably mounted on a midsole. The midsole is formed with a first compressible material and includes opposing upper and lower midsole surfaces, multiple protrusions projecting from the upper midsole surface, and multiple pockets recessed into the upper midsole surface and interleaved with the midsole protrusions. The insole, which is formed with a second compressible material distinct from the first compressible material, includes opposing upper and lower insole surfaces, multiple protrusions projecting from the lower insole surface and interleaved with the midsole protrusions, and multiple pockets recessed into the lower insole surface and interleaved with the insole protrusions. Each midsole protrusion nests within a respective insole pocket, while each insole protrusion nests within a respective midsole pocket.

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.

An article of footwear includes an upper and a sole member connected to upper. The sole member includes a plurality of tubular structures. Each of the plurality of tubular structures is at least partially filled with a loose granular material.

A sole structure for an article of footwear comprises a midsole system with a plurality of cushioning units, each having multiple cushioning layers configured to work together as a system to absorb a compressive load, such as a dynamic compressive load due to impact with the ground, in stages of progressive cushioning according to the relative stiffness values of the layers. Various midsole systems disclosed include isolated cushioning units, linked cushioning units, sole layers having stanchions interfacing with the midsole system, midsole systems with sole layers having keyed and unkeyed portions overlying a bladder, and midsole systems with vertically-stacked cushioning units disposed in inverted relationship to one another.

A midsole structure for a shoe not only maintains stability at the time of impacting the ground and improves cushioning property but also eliminates discomfort to a foot sole and improves ride feeling during running. The midsole structure (1) comprises at least two midsoles provided at a heel region of the shoe and having a hardness difference. On opposite sides of the heel region, an upper midsole (2) of a greater hardness has a thickness greater than a thickness of a lower midsole (3) of a smaller hardness. In a central part of the heel region, the lower midsole (3) of a smaller hardness has a thickness greater than a thickness of the upper midsole (2) of a greater hardness. Boundary surfaces (2B, 3A) between the upper midsole (2) and the lower midsole (3) do not appear on a top surface of the midsole structure (1) (that is, a foot sole contact surface (2A) of the upper midsole (2)).

An article of footwear includes an upper, a midsole connected to the upper, and an outsole connected to the midsole. The midsole includes a platform extending along a perimeter portion of the midsole and a lattice structure integrally formed with the platform, the lattice structure including a network of laths.

A plate for an article of footwear includes a substrate, a first strand portion attached to the substrate via first stitching, and a second strand portion disposed on the first layer. The first strand portion includes first segments that each extend between two different locations along the substrate to form a first layer on the substrate. The second strand portion includes second segments that each extend between two different locations along the substrate to form a second layer on the first layer.

A method for forming a plate includes attaching a first strand portion to a flexible substrate to form a first layer on the substrate and positioning a second strand portion on the first layer to form a second layer on the first layer in a plurality of discrete regions on the substrate. The method also includes positioning a plurality of traction elements into corresponding cavities formed into a first mold surface and positioning the substrate on the first mold surface to change a shape of the substrate. At least one of heat and pressure is applied to the first strand portion, the second strand portion, the substrate, and the traction elements to conform the substrate to the shape of the first mold surface and form the traction elements into the substrate at each of the discrete regions. The method also includes incorporating the substrate into an article of footwear.

A sole structure for an article of footwear is provided. The sole structure includes a first midsole portion, a second midsole portion, and a sheet. The first midsole portion includes a first sidewall. The second midsole portion includes a second sidewall. The sheet is disposed between the first midsole portion and the second midsole portion and extends from the first sidewall and the second sidewall. The sheet extends at least partially over the second sidewall.
