An article of footwear may have an upper with a knitted component. Alone or in combination, the knitted component may include regions with different degrees of stretch-resistance; the knitted component forms a collar with a half-gauge knit; the upper includes a strand with sections that are inlaid within the knitted component, and the sections are positioned immediately adjacent to each other; the strand forms a plurality of loops, pairs of the loops are positioned immediately adjacent to each other and configured to receive a lace; and the knitted component includes a thermoplastic polymer material, and the strand is unbonded to the thermoplastic polymer material.

A safety slipper (10) includes a stretchable fabric material upper portion (12) and a porous anti-skid lower portion. The upper portion has a foot opening (16) and a profile heel pocket (17). The lower portion (13) is made from a scrim cloth type material having a knit of polyester threads (21) coated with a soft poly-vinyl chloride outer layer (22). The lower portion provides for a cris-crossing pattern or matrix of interconnected nodes (23) with spaces (24) therebetween.

An upper structure for a shoe that improves foot fit and hold of an upper at the time of turn motion. In an upper 2 that covers a foot of a shoe wearer, an expandable part 20 is provided at a midfoot region M that corresponds to a midfoot portion of the foot, and a non-expandable part 21 is provided at a lateral side region and a medial side region except for the midfoot region M. A boundary surface between the expandable part 20 and the non-expandable part 21 is formed by a substantially flat surface. At the boundary surface, respective end portions 20E, 21E of the expandable part 20 and the non-expandable part 21 are sewn together such that a seam does not appear on the boundary surface.

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.

A knitted component for an article of footwear comprises a knit element and a tongue integrally knitted with the knit element. The knit element includes a lateral throat portion overlapping a lateral edge of the tongue and a medial throat portion overlapping a medial edge of the tongue. The lateral throat portion and the tongue are joined by a first knit structure, and the medial throat portion and the tongue are joined by a second knit structure. The first and second knit structures each include one or more courses having a plurality of knit stitches. Each knit structure may also span multiple adjacent courses. A method of manufacturing the knitted component is also described herein.

A manufacturing process involving a series of discrete operations can be modified by adding, removing, or reordering operations, without design changes to the equipment. The manufacturing process uses a frame comprising one or more alignment tabs. Each alignment tab comprises an alignment element. The alignment element interacts with a corresponding alignment element at a manufacturing station to identify to the manufacturing station the position and orientation of the frame. The frame supports a material in a known position and orientation relative to the frame, allowing the manufacturing station to infer the position and orientation of the pliable material on the frame from the interaction of the alignment elements on the frame and the manufacturing station. The operations at any particular manufacturing station can therefore be positioned independent of what operations, if any, have come before, or in what order.

An article of footwear may include an upper that has a plurality of discrete sections secured to one another. Each discrete section may include a base layer and a cover layer. Each cover layer may be secured to and may cover the outer side of a corresponding base layer. Each cover layer may be configured to be selectively removable from the base layer independently of each other cover layer to expose the outer side of the base layer. A method of manufacturing the article of footwear may include providing the plurality of base layers and providing the plurality of cover layers. The method may further include securing the cover layers to the base layers so that the cover layers cover the outer sides of the base layers.

The present disclosure provides a knitted component, the knitted component with a knit element that forms at least a portion of an upper for an article of footwear and defines an interior void for receiving a foot. A lower perimeter edge of the knit element may extend between a lateral side and a medial side of the upper. At least one strand of the knitted component may extend through the lower perimeter edge on opposite sides of the knitted component so as to extend between the lateral side and the medial side of the upper. The knitted component may be formed on a knitting machine, and the at least one strand may be configured to be tensioned to tighten the upper around a last.

A method of manufacturing a collar element for an article of footwear is disclosed. The method comprises knitting the collar element comprising a tubular structure defining an interior cavity and a plurality of floating yarns within the cavity. The method further comprises securing the collar element to an upper of the article of footwear. A method of manufacturing an upper for an article of footwear having a collar element is also disclosed.

Embodiments of the present invention relate to a thermoplastic polyurethane (TPU) infused mesh material that is molded to form at least a portion of a shoe. The TPU infused mesh may be formed as an upper, a portion of sole or other components of a shoe. The TPU infused mesh is formed, in an exemplary embodiment, through the application of liquid TPU to a surface of a spacer mesh. The liquid TPU infused spacer mesh is then cured, cut to a pattern, and heat molded to form a desired portion of the shoe. The heat molded TPU mesh is coupled to other portions of the shoe (e.g., sole) to form an article footwear in an exemplary embodiment.
