The present application discloses a molding process for shoes with inner lining, comprising: 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.

A method of manufacturing a fluid-filled chamber with a tensile element includes manufacturing a tensile element and incorporating the tensile element into a chamber. A first material layer, a second material layer, and a spacing structure having a plurality of support portions and a plurality of gaps may be stacked. The material layers may be located on either side of the spacing structure or on one side of the spacing structure. A strand may be stitched through the gaps to join the material layers and to form the tensile element. The spacing structure may be removed, and the first material layer may be spaced from the second material layer such that segments of the strand extend between the material layers. The tensile element may then be secured to opposite interior surfaces of an outer barrier, and the outer barrier may be pressurized to place the strand in tension.

The subject matter of the present disclosure is a process for manufacturing a shoe comprising an outsole joined to the sole part of a first main liner comprising on its outer face at least two studs, and a first auxiliary liner, at least partially, in particular integrally, hot-melt, in a textile piece, covering at least part of the first main liner, the outsole, and the junction between the first main liner and the outsole, at least part or all of the first hot-melt auxiliary liner being melted and adhered to the first main liner and to the outsole.

A bladder for an article of footwear includes a chamber having (i) an arcuate segment extending from a first transition to a second transition, (ii) a first plurality of elongate segments extending in a first direction from the first transition to a first terminal end, and (iii) a second plurality of elongate segments spaced apart from the first plurality of elongate segments and extending in the first direction from the second transition to a second terminal end. The bladder also includes a web area connecting the arcuate segment, the first plurality of elongate segments, and the second plurality of elongate segments and extending to a terminal edge spaced apart from each of the first terminal end and the second terminal end.

The disclosed embodiments relate to portions of an article of footwear formed from an extruded member. In certain embodiments, a sole or portion of a sole can be formed from one or more extruded members. In certain embodiments, the extruded member can be a single, continuous piece of solid material. In certain embodiments, a sole for an article of footwear can be fashioned from an extruded member formed in a controlled geometric pattern. In certain embodiments, the sole can include one or more layers.

The present invention relates to a mould (10) for producing footwear (1) by means of direct injection onto the upper (2) of a sole (3), comprising a tread (5) and a midsole (4), wherein the midsole (4) is composed of a first layer (6) and a second layer (7). The mould (10) comprises a base (12), a pair of first half-rings (14), a pair of second half-rings (16), a first cover (18), a second cover (20) and a mould last (22). In accordance with the invention the mould (10) comprises gripping means (24) designed to fix selectively the first half-rings (14) to the base (12) or to the second half-rings (16). The present invention also relates to a method for producing footwear (1) using said mould (10).

A multi-layer decorating element includes a base and a plurality of plates forming decorative elements. The base has a length between the first and second ends thereof and an increased width from the first end to the second end. The first end of the base is curved. The second end of the base is divided by a gap into two segments. The gap has a closed end and an open end. The open end is disposed at the second end of the base. The closed end has a smaller width than the open end. The plurality of plates includes a side with a hot melt glue layer and is hot pressed on a side of the base. The plurality of plates is disposed within peripheral edges of the base and includes a plurality of overlapped sections. The plurality of plates has different shapes.

Provided are, among other things, systems, methods and techniques for making a shoe outsole and to shoe outsoles made using such techniques. In one such technique, a sheet of composite material is produced by extruding a base material together with a sheet of fabric material. The sheet of composite material is then cut into an outsole component, and a shoe outsole is fabricated using the outsole component.

The present invention relates to an upper for a shoe, including an inner layer; an outer layer overlapping the inner layer at least partially; wherein the outer layer includes a plurality of cuts; wherein the inner layer includes a plurality of protrusions; wherein each cut at least partially overlaps at least one protrusion; wherein each protrusion causes an extension in width of its corresponding cut when the shoe is worn.

Improved soles and insoles for shoes, in particular sports shoes, are described. In an aspect, a sole for a shoe, in particular a sports shoe, with at least a first and a second surface region is provided. The first surface region comprises expanded thermoplastic polyurethane (“TPU”). The second surface region is free from expanded TPU.
