Articles of footwear, including athletic footwear, include one or more of: (a) an upper; (b) a sole structure including a midsole and an outsole, the outsole having a plurality of polygonal lugs arranged about a base surface of the outsole. The outsole may include one or more regions wherein the characteristics of a portion of the lugs within a region differ from the characteristics of a portion of the lugs in another region. The lugs may differ, for example based on size, construction and/or spacing between the lugs. Methods of manufacturing such articles of footwear also are disclosed.

A compressible footwear that may include a compressible sole and a compressible upper part that is mechanically coupled to the compressible sole. The compressible sole consisting essentially of multiple compressible cells that are made of a flexible material and have top openings and bottom openings. The multiple compressible cells span over at least a majority of the compressible sole and are configured to undergo a compression while substantially maintaining a thickness of the compressible sole.

Methods for preparing a footwear article are disclosed herein. An example method may comprise disposing resin adjacent a mold, disposing a lattice structure in at least a portion of the resin disposed adjacent the mold, closing the mold using a lasted upper, injecting foam into the closed mold such that the foam operates to couple the lasted upper and the lattice structure together.

Novel semi-permanent and/or permanent high heel repair device and/or decorative cover slips over the original material on a high heel to either change the decoration, protect the original high heel material from damage, or to cover damage that occurred on the high heel or on the underlying high heel material. The invention comprises a tube of material in a variety of shapes (depending on the shape of the high heel) with one end of the tube closed, or both ends open. If one end is closed, the closed end has a small hole in it allowing for a heel tip dowel to pass through, stopping at the heel tip (neither the dowel nor the heel tip are part of the device), which helps secure the invention to the high heel. The invention may be semi-permanently attached using this method or permanently attached using this method or additional adhesive or another fixative. The shape of the invention can match the profile of the high heel or be a different profile from the high heel. The invention will be created in several sizes, heights, thicknesses and profiles to fit on several different high heels and either mimic the high heel's original shape or may change the original high heel shape.

Presented are systems, methods, and devices for manufacturing articles of footwear using sacrificial straps to secure segments of the footwear to a manufacturing fixture. A method for manufacturing an article of footwear, such as an athletic shoe, includes providing first and second segments of the footwear's upper, such as the vamp and heel counter. A sacrificial strap is removably attached at opposing ends thereof to the first segment, e.g., proximate a read edge of the vamp. The first segment is placed on a manufacturing fixture, such as a foot-shaped last, and securely attached to the fixture by positioning the sacrificial strap around and against the fixture. The second segment of the upper is attached, e.g., via stitching or bonding, to the first segment. Once attached, the upper is removed from the manufacturing fixture, and the sacrificial strap is cut, torn or otherwise permanently disconnected from the footwear.

A process for manufacturing a multi-layered sole directly on the upper, of the type that employs the technique known as “direct injection on the upper”, by which soles are made of a plastic material and consist of a plurality of layers with different colour, density, softness and physical-mechanical properties. Said layers form at least an external sole, called “outsole”, an internal sole, called “insole” that adheres and extends only partially or totally on the surface of the upper, and an intermediate sole, called “midsole”, that is intended to hold the other two above-said soles. Said process provides for the use of a single mould which is brought, when suitably equipped, in a well-defined sequence, in front of at least three distinct injectors (I.sub.1, I.sub.2, I.sub.3) in order to obtain, also in sequence, by at least a first moulding operation (P.sub.1) the lower portion of the sole, i.e. the “outsole”, by at least a second moulding operation (P.sub.2) the upper part of the sole, i.e. the “insole” and by at least a third moulding operation (P.sub.3) the “midsole”.
