A molding process for shoes with inner lining comprises: placing a molding inner core sleeved with an inner lining in a combined external mold being preset with a semi-molded shell; performing a mold-closing action to make the semi-molded shell in the first external mold and the second external mold attach to the inner lining, respectively; and heating to vulcanize the semi-molded shell, and combining with the inner lining to produce a shoe with inner lining.

An improved article of footwear includes a sole structure and an upper. The upper is coupled to the sole structure and is configured to receive at least a portion of a human foot. The upper further includes a toebox, a medial quarter, a lateral quarter, a heel cup. The upper also includes a three dimensional auxetic structure at least partially formed within the medial quarter, lateral quarter, and heel cup of the upper. The three dimensional auxetic structure defines a primary expansion direction, a secondary expansion direction, and a tertiary expansion direction. The secondary expansion direction is transverse to the primary expansion direction. The tertiary expansion direction is normal to the plane defined by the primary expansion direction and the secondary expansion direction. Furthermore, the upper of the article of footwear is constructed via a thermoforming process.

An upper for an article of footwear, the upper including a base layer defining a least a portion of the upper and polymer threads stitched to the base layer. The polymer threads may include a core composed of a first material and a coating composed of a second material, where the melting point of the first material is higher than the melting point of the second material. The polymer threads may be bonded to the base layer by the coating of the polymer threads. The polymer threads may include one or more polymer thread sets stitched in pattern(s) on area(s) of an outer surface of the base layer to provide targeted characteristics to area(s) on the upper. In some embodiments, the polymer threads may be bonded to the base layer with heat and/or pressure.

According to embodiments of the invention, a precursor sheet is formed by injecting an EVA-based material into a mold cavity. The mold cavity is configured to create a series of indentations through a first portion of the precursor sheet and into a second portion of the precursor sheet. The precursor sheet is removed from the mold cavity and the second portion of the precursor sheet is removed from the first portion of the precursor sheet to create an isolated sheet with a series of through-holes. The isolated sheet is then formed into a portion of a shoe.

An upper for an article of footwear includes a spray formed first layer including a first material, and a second layer including a second material, the second layer being adhered to the first layer. A transition zone is defined at a transition between the first layer and the second layer, and the transition zone includes a mixture of the first and second materials.

A last for forming an upper of an article of footwear includes an exterior surface, where the exterior surface includes a plurality of three dimensional structural surface components disposed over at least 50% of the exterior surface of the last.

A method of forming an upper for an article of footwear includes providing a first material layer over a shoe last, providing a second material layer over the first material layer such that the first and second material layers adhere to each other at an interface between the first and second material layers, where one or both of the first material layer and second material layer is provided by spray forming a polymer material onto the last. The material layers are removed from the last and turned inside out such that the first material layer includes an exposed surface that forms an exterior surface of the upper.

Methods for manufacturing an upper for a shoe, in particular a football shoe, are described. A base layer for an upper is provided. At least one profile element, which comprises a rubber material, is connected to the outer face of the base layer. The profile element is connected to the outer face of the base layer without using a seam by means of hot pressing.

Articles of wear having one or more textiles that include a low processing temperature polymeric composition and a high processing temperature polymeric composition, and methods of manufacturing the same are disclosed. The low processing temperature polymeric composition and the high processing temperature polymeric composition can be selectively incorporated into a textile to provide one or more structural properties and/or other advantageous properties to the article. The textile can be thermoformed to impart such structural and/or other advantageous properties to the article of wear. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
