The present invention relates to a high-heeled shoe comprising an insert (E) and a base body (G), wherein the base body (G) is produced as a single part via a 3D printing process. The insert (E) comprises a surface (EF) that has an upper side (EO) and a lower side (EU), wherein a heel (A) is formed on the lower side (EU). The base body (G) comprises a base surface (F) and an inner flap (I), wherein the base surface (F) has an upper side (FO), a lower side (FU) and a first cavity (H1), and the inner flap (I) has an upper side (IO) and a lower side (IU), wherein the lower side (IU) of the inner flap (I) is joined with the upper side (FO) of the base surface (F) of the base body (G) such that, between the lower side (IU), the upper side (FO) and the first cavity (H1), a second cavity (H2) is formed which forms an overall cavity (HG) with the first cavity (H1), wherein the overall cavity (HG) essentially corresponds to the shape of the insert (E). The insert (E) is positioned in the overall cavity (HG) such that the lower side (EU) of the surface (EF) of the insert (E) is completely contacted with the upper side (FO) of the base surface (F) of the base body (G), and the lower side (IU) of the inner flap (I) completely covers the upper side (EO) of the surface (EF) of the insert (E). The present invention furthermore relates to a process for producing the high-heeled shoe and to the use of an inner flap (I) for completely covering the upper side (EO) of the surface (EF) of an insert (E) in a high-heeled shoe.

Two part sole structures are provided having a first foam component containing a polyolefin resin with a polyurethane resin component adhered to a surface of the first foam component. For example, in some aspects, a sole structure or a portion thereof is provided having a first sole component containing a foam composition and a second sole component adhered to a surface of the first sole component, where the second sole component includes a polyurethane resin. The second sole component is in some aspects printed or extruded onto the surface of the foam. In particular, midsoles including the foams and having an outsole component on the ground facing portion are provided for use in an article of footwear. Methods of making the sole structures are provided, as well as methods of making an article of footwear including one of the sole structures.

A process for injection molded microcellular foaming various flexible foam compositions from biodegradable and industrially compostable bio-derived thermoplastic resins for use in, for example, footwear components, seating components, protective gear components, and watersport accessories wherein a process of manufacturing includes the steps of: producing a suitable thermoplastic biopolymer or biopolymer blend; injection molding the thermoplastic biopolymer or biopolymer blend into a suitable mold shape with inert nitrogen gas; controlling the polymer melt, pressure, temperature, and time such that a desirable flexible foam is formed; and utilizing gas counterpressure in the injection molding process to ensure the optimal foam structure with the least amount of cosmetic defects and little to no plastic skin on the outside of the foamed structure.

A method of manufacturing a multicolor shoe material includes the following steps. Step S1: blank molds are provided, and a mold chamber of each of the blank molds is injected by one of the foamed materials in different colors to form unfoamed semi-finished products in different colors. Step S2: the semi-finished products are put into a foaming mold, when the foaming mold is preheated and completely closed, a ratio of a total volume of the semi-finished products to a volume of the mold chamber of the foaming mold is ranged between 0.96 and 1.04. Thus, the semi-finished products could be evenly foamed. After foaming, adjacent two of the semi-finished products could be connected by heat fusion to obtain the multicolor shoe material. Additionally, a semi-finished product and a multicolor shoe material are provided in the present invention.

A variety of plates for footwear are provided including a polyolefin resin. Sole structures and articles of footwear formed therefrom are also provided. Methods of making the polyolefin resin compositions, plates, sole structures, and articles of footwear are also provided. In some aspects, the polyolefin resin composition includes an effective amount of a polymeric resin modifier. The effective amount can be an amount effective to allow the resin composition to pass a flex test, and in particular to pass a flex test without significant change in abrasion loss. In some aspects, the resin composition also includes a clarifying agent to improve optical clarity of the plate. In some aspects, the plates include a textile disposed on one or both of a first side and the second side of the plate. The textile can provide for improved bonding of the plate to other components such as a chassis or an upper.
