Embodiments of the present invention relate to a shoe construction that includes an upper that has an interior surface and a corrugated exterior surface of rapid manufactured material. The upper interior surface and corrugated exterior surface form a lattice-interlace surface. The lattice-interlace surface includes the interior surface that has a plurality of horizontal laths, the corrugated exterior that has a plurality of vertical laths, and a plurality of lattice apertures that extend from an interior of the shoe to an exterior of the shoe. The shoe construction further includes an interior sole portion of sintered material. The interior sole portion forms a tessellated framework. The tessellated framework includes a lattice of hollow cubes; each hollow cube has a top surface opening and a bottom surface opening, the openings extending from an interior of the shoe to an exterior of the shoe.

Ground-engaging components (240) for articles of footwear (200) include an upper (202)-facing surface (222S) and a ground-facing surface (248G) opposite the upper (202) facing surface (222S). At least the ground-facing surface (248G) may be formed to include a matrix structure (250), and this matrix structure (250) may include a plurality of open cells (252) (e.g., in a heel region (252H) and/or a midfoot region (252M)) and a forefoot region (252F) including a plurality of closed forefoot support cells (252). The ground-engaging component (240) may be engaged with a midsole member (220) (e.g., including a foam midsole element (222F) and/or one or more fluid-filled bladders (222A, 222F), and this combination may form a sole structure (204) that is engaged with an upper (202) to form an article of footwear (200).

An insole for ergonomic shoes according to an embodiment of the present disclosure, including: a plurality of first polygonal grooves that are formed to be arranged in polygonal shapes on a lower surface of the insole; a first wall portion forming a rim of the first polygonal groove; and a second polygonal groove that is disposed in a pressure distribution portion, which is a part of an inner and lower surface of the insole, and is formed of a rim including a second wall portion having a height lower than a height of the first wall portion.

Improved soles for shoes, in particular sports shoes, are described. A sole for a shoe, in particular a sports shoe, is provided that includes a midsole with randomly arranged particles of an expanded material. The sole further includes an element having a higher deformation stiffness in at least one direction than the expanded material. The material of the midsole at least partially surrounds the element.

The present invention relates to a method of forming an item of footwear (100) and an item of footwear (100). In particular, the item of footwear (100) is a boot formed of vulcanised rubber such as a Wellington boot. A method of forming an item of footwear (100) comprising the steps of providing a sole member (2) formed of a first rubber material having a first compressive resistance, the sole member (2) comprising a cavity (4) in an upper surface (2A) of a heel region of the sole member (2); placing an insert (6) into the cavity (4), the insert (6) having a second compressive resistance lower than the first compressive resistance; and then vulcanising to thereby attach an upper part (8) formed of a second rubber material to the sole member (2) at a first temperature, wherein the insert (6) is formed of a material which is solid at the first temperature.

An orthotic device for footwear. In one embodiment the orthotic device comprises a substantially planar body having a resiliently deformable outer peripheral portion, a cell frame, and an inner array of detachably coupleable cells, wherein each cell comprises one or more protuberances and/or recesses which permit the cells to detachably couple with the cell frame.

A cycling shoe including an upper part configured to receive a foot of a user, an outsole disposed on a bottom of the cycling shoe, and a midsole disposed between the upper part and the outsole, the midsole including a nanofoam and having a hardness between 45 D and 65 D, inclusive, as measured by a durometer.

An orthotic footwear system including a removable outsole, a removable reinforced hollow midsole attached to the top of the outsole, and a removable insole attached to the top of the midsole. A removable metatarsal pad can be attached to the top of the insole, and removable support inserts can be attached around the insole for additional support of problematic areas. Support inserts can be used to support the arch area, the heel area, or both. Each of the removable parts can be interchanged with parts of the same type having different ergonomic characteristics. The user can change the parts of the orthotic to suit their needs. Further, the support inserts can be used apart from the rest of the system, with any insole configured to receive them.

Footwear articles are disclosed herein. Footwear articles may be formed using a method comprising disposing uncured resin adjacent a mold, disposing a lattice structure in at least a portion of the uncured resin disposed adjacent the mold, closing the mold using a lasted upper, and injecting foam into the closed mold such that the foam operates to couple the lasted upper and the lattice structure together.

A footwear sole structure may include a plurality of discrete hexagonally-shaped sole elements defined by a plurality of sipes. The sipes may include a plurality of sipes that extend in a transverse direction across the sole structure and a plurality of sipes that extend in an oblique direction relative to the transverse sipes. A plurality of sipes may also subdivide the hexagonally-shaped sole elements into one or more diamond-shaped sole element portions. The sole structure may include additional features such as non-hexagonal sole elements and lugs distributed across a bottom surface of the sole structure.
