An article of footwear is disclosed that includes an upper articulated sole structure. The sole structure includes a connecting portion and a plurality of discrete sole elements. The connecting portion is positioned adjacent the upper and may extend along a longitudinal length of the upper. The sole elements extend from the connecting portion, and the sole elements are separated by a plurality of sipes that extend upward into the sole structure. The plurality of sipes includes: a first sipe oriented in a longitudinal direction and extending through forefoot, midfoot and heel regions, a second sipe extending longitudinally through only the forefoot region, and a plurality of third sipes extending laterally and straightly between medial and lateral sides of the footwear. A first portion of the third sipes extending in directions non-parallel to directions of a second portion of the third sipes, the connecting portion and the sole elements being formed of polymer foam material and a thickness of the connecting portion varying between the forefoot and the heel regions.

An article of footwear (10) is disclosed that includes at least one of a stretchable upper (20) and an articulated sole structure (30). The upper may include an exterior layer (14) and an interior layer (15). The exterior layer forms at least a portion of an exterior of the upper, and the exterior layer includes a plurality of incisions (27a,27b) that extend through the exterior layer. The interior layer is located adjacent an inner surface of the exterior layer, and the interior layer is exposed through the incisions. The sole structure may include a connecting portion (40) and a plurality of discrete sole elements (51). The connecting portion is positioned adjacent the upper and may extend along a longitudinal length of the upper. The sole elements extend from the connecting portion, and the sole elements are separated by a plurality of sipes (52a-52b) that extend upward into the sole structure.

Methods and apparatuses for manufacturing components used in the manufacture of wearable articles are presented. Some of the methods of manufacturing a mold and the apparatuses themselves include, among other features, forming a plate (102) having a mold insert (112). The mold insert is removably connected to the plate and is formed using a rapid prototyping technique. In addition, methods for manufacturing wearable articles are presented. The methods generally including forming a mold (100), including a mold insert (112) formed using a rapid prototyping technique. In addition, the methods include performing the steps of a molding operation on the mold. The molding operation may include any of several known molding operations.

A vapor-permeable and waterproof sole for shoes, including a tread including a plurality of through holes, a multilayer pack, arranged superimposed on the region where the through holes are provided and including a membrane, permeable to water vapor and impermeable to liquids, and a protective layer, arranged directly below the membrane. The tread is overmolded onto the pack and further surrounds the edges, the lower perimetric portion, and the upper perimetric portion of the pack to form a perimetric seal adapted to avoid rise of liquids. The pack includes a vapor-permeable or perforated layer element, arranged directly below the protective layer, superimposed on the through holes region. The layer-like element avoids contact of the molding polymeric material with the protective layer during tread molding, and is further associated with the protective layer.

A shoe with breathable and waterproof sole and upper, comprising a breathable and waterproof sole (11) and an assembly (12) that is associated with the sole (11) in an upward region and is constituted by: - an external breathable upper (13), an internal lining (14) and, between them, a breathable and waterproof membrane (15), - an at least partially perforated or breathable insole (16), which is joined at least to the upper (13) and to the breathable and waterproof membrane (15). The shoes thus composed, have the particularity of having a sole (11) that is joined hermetically and peripherally to the assembly (12) at the connecting region (17) between said upper (13) and the breathable and waterproof membrane (15).
摘要:
A method of forming a cross-linked foam is provided in the present invention. The method includes the steps of preparing at least one foaming material for cross-linked foaming, the foaming material processed to have a plane or three-dimensional shape with the cross-linked foaming suppressed; forming at least one interfacing pattern on a surface of at least one interfacing pattern on a surface of at least one of the foaming material using at least one interfacing material that prevents chemical and physical interaction between the foaming materials; and forming a cross-linked foam by foaming the foaming material having the interfacing pattern thereon, the cross-linked foam having a foam body and an internally-formed surface.
摘要:
A mould for a gas assisted method of injection moulding has first and second mould parts defining a mould cavity. A series of upstanding ribs extend from the surface of the mould defining the mould cavity. These ribs produce complementary channels (30) in a moulding produced in the mould. These channels (30) split the mould cavity into a plurality of communicating sub-sections (31). Channels are provided splitting the ribs into sections and forming, during the moulding process, connecting ribs (35) of plastic between the plastic adjacent the channels (30). These ribs contribute to the lateral rigidity of the moulded product. The sub-sections enable an otherwise uncontrollable void to be divided into controllable smaller voids.
