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.

The present disclosure provides a solid curable transparent rubber composition containing one or more synthetic isoprene polymer, one or more transparent polymer, one or more curing agent, additives that do not influence transparency and one or more polyalkenamers. The solid curable transparent rubber composition, once cured, has a haze of less than 30% and a total light transmission of more than 80%. The disclosure further provides a cured transparent rubber composition made thereof, and a manufacturing process for the cured composition. The present disclosure also provides an article including the rubber composition, in particular shoes with transparent soles.

The soft boot and liner includes moisture transfer system that includes an inner fabric layer carefully selected from technically advanced fabrics. A series of layers are provided outside the inner liner including foam material layers, spacer fabrics and breathable membranes, in various orders. Encapsulation technology and waterproofing are used as well. The outer fabric layer is also capable of working with the other layers to promote the transfer of moisture. Frothed foams and flocking with fibers are further characteristics of the present invention. The moisture transfer system is incorporated into a soft boot or skate or as a removable liner for a shell boot. Numerous other modifications and applications are disclosed.

A method for producing antibacterial shock absorbing shoes is provided. The method includes the following steps of: designing a shoe tree and a shoe style, and selecting a material; attaching paper to an outside of the shoe tree to make a paper pattern; manufacturing a bottom pad, a middle pad and a foot pad, and punching a circular hole in the middle pad; soaking the leather pad with an antibacterial agent, punching semi-spherical protrusions and a connecting groove on the leather pad, forming a circular pinhole in a top end of the semi-spherical protrusion, pasting the leather pad on the middle pad with a glue and cutting the leather pad to manufacture a shock absorbing massage pad; wrapping the shoes, and shaping; and placing the shock absorbing massage pads and the foot pads into the shoes. The shoes manufactured have good breathability, shock absorbing property and antibacterial property.

The modular footwear covering system includes a detachable cover and a shoe able to accept the cover. The upper part of the cover is shaped to conceal a vamp of the shoe and has tails which extend around the left and right of the ankle of the shoe, able to fasten to the heel in order to secure the upper around the ankle of the shoe. The lower part of the cover takes the shape of the sole with enough excess material to slightly extend upwardly around the extremities of the vamp and overlap with the upper. The lower part is elastic, and contains an X-shaped tensioner to evenly tighten the upper around the vamp of the shoe. A corresponding recess in the shoe is able to receive the X-shaped tensioner and provides a reliable mechanical interface to tension and retain the cover about 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).

Presented are manufacturing systems, methods, and devices for forming footwear using scrap or waste plastic materials. A method for manufacturing an article of footwear, such as an athletic shoe, begins with receiving a batch of recycled plastic, which may include thermoplastic elastomers or ethylene-vinyl acetate, and grinding the batch of recycled plastic material. The ground recycled material is processed, for example, by adding a foaming agent that activates at elevated temperatures. The processed recycled material is placed into the internal cavity of a final mold that is shaped like a segment of the footwear, such as a unitary sole structure. To form the footwear segment, the processed recycled material is heated past the threshold activation temperature of the foaming agent such that the foaming agent causes the recycled material to expand and fill the internal cavity of the final mold. The formed footwear segment is then extracted from the mold.

One or more aspects of the present disclosure provide articles of manufacture and components of articles that incorporate an optical element that imparts structural color to the component or the article. The component comprises a cured or curable material, and can include or be made to have a textured surface.

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.

A smartphone or other mobile computer device, general purpose or specialized, wherein the smartphone device is configured to actively control the configuration of one or more bladders, compartments, chambers or internal sipes and one or more sensors located in either one or both of a sole or a removable inner sole insert of the footwear of the user and/or located in an apparatus worn or carried by the user, glued unto the user, or implanted in the user. The one or more bladders, compartments, chambers, or sipes, and one or more sensors are configured for computer control. A sole and/or a removable inner sole insert for footwear, including one or more bladders, compartments, chambers, internal sipes and sensors in the sole and/or in a removable insert; or on an insole; all being configured for control by a smartphone or other mobile computer device, general purpose or specialized.
