An article of footwear has a sole assembly with a cushioning component and a shell that has a textile layer. The cushioning component is positioned in a cavity of the shell so that the cushioning component is supported on a lower surface by the shell and the upper surface of the cushioning component is uncovered by the shell at an opening of the shell. A method of manufacturing an article of footwear includes forming an at least partially textile shell so that the shell has a cavity with an opening. A cushioning component is positioned in the cavity of the shell so that a lower surface of the cushioning component is supported on an inner surface of the shell and is uncovered by the shell at the opening. The lower surface of the cushioning component is secured to the inner surface of the shell by radio frequency welding or adhesive.

A three-dimensional auxetic structure, comprising a plurality of adjoining hollow cells, each hollow cell having cell walls and a transversal cross section of the plurality hollow cells following a two-dimensional auxetic pattern, each cell wall comprising folding lines parallel to a plane containing the auxetic pattern such that peaks and valleys are defined in the cell walls and the cell walls being foldable along the folding lines.

An article of footwear includes an upper comprising a knitted component forming a one-piece integrally knit element that forms a lower portion of the upper and extends from the lower portion toward a collar. The lower portion of the upper is configured to extend under a wearer's foot. The article of footwear includes an insert member having a bottom side with a plurality of protuberances that extend away, and the lower portion of the upper is vacuum molded around at least some portions of the protuberances of the insert member. The article of footwear may also include a sole assembly secured to the bottom side of the lower portion of the upper.

A sole construction (10) for use in a high heel shoe (60) comprises at least a first skeleton sole (11) formed from a composite material such as a carbon fibre material. The skeleton sole (11) has lasting allowances (15) defined around the perimeter thereof and adapted to receive the edges of a shoe upper (61) when incorporated in a high heel shoe (60). The skeleton sole (11) is further shaped so as to define one or more recesses (16) generally centrally therein. When incorporated into a high heel shoe (60), the enhanced strength, rigidity and flexibility of the sole construction (10) allow for the use of a range of interchangeable heel constructions (30,40,50) having different heel heights.

Sole for footwear capable to adapt itself to shape or to deformations of the user's foot includes a first layer on which, in the part at the forefoot, at least a first cut is made, passing approximately in a longitudinal direction of the sole and proximal to the first lateral edge of the sole. A second layer is attached to the first layer, on which a second through cut is made, approximately according to a longitudinal direction of the sole, arranged proximal to a second lateral edge of the sole. A double-sided adhesive layer is attached to the first layer so as to be interposed between the first and second layers and to overlap the lips of the second cut. A-protective film is attached on a face of the double-sided adhesive tape in contact with said second layer, wherein the film projects outside the sole through the first cut.

Debondable adhesive compositions are provided. This disclosure also provides articles of footwear and components for articles of footwear including a debondable adhesive matrix. The debondable adhesive matrix can allow for the bonding and debonding of two substrates in the article of footwear or component thereof. This disclosure also provides methods of making the debondable adhesive compositions and methods of using said compositions for bonding and debonding the substrates, e.g. for bonding and debonding of an upper and an outsole in an article of footwear.

A sole structure for an article of footwear comprises a sole plate including a midfoot region and at least one of a forefoot region and a heel region. The sole plate has an undulating profile at a transverse cross-section of the sole plate. The undulating profile includes multiple waves each having a crest and a trough. The sole plate has ridges corresponding with the crest and the trough of each wave and extending longitudinally throughout the midfoot region and the at least one of a forefoot region and a heel region.
