A sockliner for a shoe or other article of footwear is formed having at least one generally flat, planar surface. At least a portion of the sockliner has a linear width that exceeds the linear distance across a width of the shoe. When the sockliner is placed in the shoe, pressure on the wider portions of the sockliner changes the conformation of the sockliner to conform to the shoe.

A sockliner for a shoe may be formed to include an integral fabric skirt. The fabric skirt may remain loose from the sockliner along at least a portion of the periphery of the sockliner. The loose periphery of the fabric skirt may be used to join the sockliner to other shoe components, as in a strobel-type seam.

Aspects hereof relate to a multi-part mold for molding articles of footwear having sole regions of differing materials forming a desired outsole surface material pattern. The multi-part mold includes a carrier mold portion and a tray mold portion. The carrier mold portion provides definition to the lateral surfaces of a resultant co-molded product. The tray mold portion cooperates with the carrier mold portion and provides definition to another (e.g., bottom) surface of the resultant co-molded product. The tray mold portion generally includes at least one pod or cavity for receiving a first material that when cured/catalyzed, defines a patterned other (e.g., bottom) surface of the resultant product. A multi-part mold having the structure as described herein permits interchangeability of multiple tray mold portions with a single carrier mold portion.

The invention relates to a mould (1) for manufacturing three-dimensional items, comprising a body (2); a lid (4) configured to close said body (2); and incorporated closing and opening means (5) configured to keep the body (2) and the lid (4) joined during the movement thereof. A machine (M1) for manufacturing three-dimensional items, comprising a receiving module (M2) configured to receive the mould (1); a conditioning module (M3) configured to receive the mould (1) from the receiving module (M2) and act on the incorporated closing and opening means (5) in order to separate the lid (4) from the body (2); and a handling module (M4) configured to receive the body (2) from the conditioning module (M3) and enable the placement of the components of the item to be manufactured. A method for manufacturing three-dimensional items and manufacturing plant associated with said machine (M1).

A method of manufacturing a midsole includes placing first and second preforms into a midsole recess of a mold, with first and second portions of the mold defining a first overflow chamber connected to the first recess; closing the mold by positioning the first and second portions in contact with one another; heating the mold for a predetermined period of time at a predetermined temperature such that the first and second preforms melt and bond together to form a midsole, with a portion of each of the first and second preforms flowing into the first overflow chamber to form a first overflow portion; removing the midsole from the mold; allowing the midsole to expand; and cutting away the first overflow portion.

Cleat structures, e.g., for golf shoes, may include a flat and flexible interior surface and/or a generally disk-shaped perimeter area that includes features to promote in-molding of the cleat to a footwear sole component (e.g., to permanently engage the cleat with an outsole member). Such cleats may provide a flexible and comfortable base, including a low profile, e.g., to enable formation relatively thin and/or flexible footwear sole components. Footwear sole components and articles of footwear that include one or more in-molded cleat structures of this type also are described. Molds used for in-molding procedures and methods of using the molds to make articles with in-molded components (e.g., for making footwear sole structures including one or more in-molded cleats) also are described.

An insole may include an insole body in a shape receivable in a shoe; an electronic element provided in the insole body; a connection line configured to electrically connect to the electronic element and including a contact terminal exposed to the outside of the insole body; and a connector including a detachable member configured to at least partially protrude outward from the insole body and configured to support the contact terminal.

Methods for manufacturing uppers for articles footwear that include thermo-forming an upper composed of one or more low melting point thermoplastic polymers. The methods may include disposing a skin for forming an upper over and inflatable bladder. The skin may include at least one of a base layer composed of a low melting point thermoplastic polymer and a grid layer including a yarn composed of a low melting point thermoplastic polymer. The skin and inflatable bladder may be placed into a mold cavity and the mold may be heated to a predetermined temperature. The inflatable bladder may be inflated such that the skin is pressed against an interior surface of the heated mold cavity to cause the skin to take on the shape of the internal surface of the mold cavity, thereby forming an upper for an article of footwear.

Articles of footwear including a thermo-molded upper having a skin composed of one or more low melting point thermoplastic polymers. The skin may include at least one of: a base layer composed of a low melting point thermoplastic polymer and a grid layer including a yarn composed of a low melting point thermoplastic polymer. The uppers may be formed by placing a skin and an inflatable bladder into a mold cavity and heating the mold to a predetermined temperature. The inflatable bladder may be inflated such that the skin is pressed against an interior surface of the heated mold cavity to cause the skin to take on the shape of the internal surface of the mold cavity, thereby forming an upper for an article of footwear.

An article of footwear includes a sole structure including a polymeric bladder element enclosing a fluid-filled interior cavity. The bladder element has a surface with a groove that extends generally parallel with a transverse edge from a lateral side to a medial side, and has a reduced thickness at the groove. A first length along a longitudinal midline of the bladder element from a longitudinal extremity of the bladder element to the groove corresponds with a first footwear size, and a second length along the longitudinal midline of the bladder element from the longitudinal extremity to the transverse edge corresponds with a second footwear size larger than the first footwear size. The sole structure is used in a method of manufacturing an article of footwear.
