An article of footwear has an upper that is direct attached with the sole in a article of footwear mold. The sole has a film extending up sidewalls of the sole to a film edge that is prior to the sidewall and the upper joining. Method of manufacture of the article of footwear includes steps of positioning a film over a mold cavity and then securing the film to the mold. The film is heated and then drawn into the mold cavity under a vacuum. The film forms a liner of the mold cavity. A foam composition is injected into the lined mold cavity. As the foam composition expands, the foam composition interacts with and mechanically engages with the upper that is poisoned at the mold cavity to allow for the mechanical engagement that results in the direct attach of the sole to the upper.

An article of footwear has an upper that is direct attached with the sole. The direct attach sole has an insert, such as an airbag, that forms a portion of a sidewall. The insert is externally visible and forms at least a portion of an external sidewall of the sole. The insert is formed into the direct attach sole by having the insert or a mask temporarily joined with the insert contact a sidewall molding surface of a mold used in the direct attach operation such that the insert results in forming a visible element of the direct attached sole.

A plastic composition includes a polymer component. The polymer component includes an ethylene-vinyl (EVA) copolymer, a first ethylene--olefin copolymer having a hardness ranging from 55 Shore A to 60 Shore A measured according to ASTM D2240, a second ethylene--olefin copolymer having a hardness ranging from 85 Shore A to 90 Shore A measured according to ASTM D2240, and polypropylene (PP). The plastic product made from the composition has a loss factor ratio of tan (20 C.) to tan (40 C.) at a frequency of 10 Hz, which ranges from 2.5 to 3.8. A midsole and a method of producing the midsole are also disclosed.

A mould for manufacturing three-dimensional items, comprising a body; a lid configured to close the body; and incorporated closing and openings configured to keep the body and the lid joined during the movement thereof is disclosed. A machine for manufacturing three-dimensional items, comprising a receiving module configured to receive the mould; a conditioning module configured to receive the mould from the receiving module and act on the incorporated closing and openings in order to separate the lid from the body; and a handling module configured to receive the body from the conditioning module 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 the machine.

A procedure for making a shoe with a knitted upper, including a series of steps in whichduring an upper shaping steponce the internal stocking has been placed on the shoe tree, a membrane element (3) is placed in position, which covers the portion corresponding to the sole of the shoe tree and a lateral portion. The membrane element is a single-body element formed of a polymer membrane that has adhesive material on both sides thereof and features a series of suitable shaped and positioned perforations (30). The membrane element is designed to create a support structure for the two stockings so that the shoe obtained has and maintains a structured shape. Once the upper is complete, a sole is constructed by injection moulding in order to create a shoe that is a single, homogeneous, compact, and structured body.

An article of footwear includes an upper having a first ground facing surface. A primary sole part has a first foot facing surface and a second ground facing surface. The first foot facing surface includes a plurality of openings. Each opening defines a volume extending in a vertical direction from the first foot facing surface towards the second ground facing surface, which has a closed end. A secondary sole part has a second foot facing surface and a third ground facing surface. The secondary sole part is arranged between the upper and the primary sole part and extends into the plurality of volumes and/or openings in the first foot facing surface of the primary sole part.
