SEPARABLE AND REGENERATIVE FOOTWEAR

A separable footwear article comprising an outsole oriented at a bottom of the footwear and configured for ground contact, the outsole comprising a first material, an upper portion comprising a second material different from the first material, and a welt positioned between the outsole and the upper. The welt is releasably coupled to the outsole with a first thread using a first stitching technique, and releasably coupled to the upper portion with a second thread using a second stitching technique. The outsole, the upper portion, and the welt are configured to be separated upon receipt of a pulling force upon the first thread and the second thread sufficient to remove the first thread and the second thread from the footwear article.

String guide module and use thereof in a machine with a string puller

The present application for Patent of Invention describes a strand guide module which enables the use of locks to be fully eliminated for adjusting the waist, considerably improving the quality and comfort of the footwear, besides economizing raw materials and improving productivity. The purpose of the object of the invention is to allow for longitudinal, latitudinal and angular adjustment of the pulling vector of the strands, particularly the longitudinal positional adjustment along the last (F), including modularity characteristics.

SEPARABLE AND RECYCLABE FOOTWEAR

A separable footwear article may comprise an outsole oriented at the bottom of the footwear and configured for ground contact, the outsole comprising a first material; an upper portion releasably coupled to the outsole with thread using chain stitching, the upper portion comprising a second material different from the first material; and an insole removeably disposed adjacent the upper portion and the outsole, the insole comprising a third material different from the first material and the second material; wherein the outsole, the upper portion, and insole are capable of being separated by releasing the thread and hand pulling the thread from the footwear article.

Ground-engaging structures for articles of footwear

Ground-engaging components for articles of footwear include: (a) an outer perimeter boundary rim that at least partially defines an outer perimeter of the ground-engaging component, wherein the outer perimeter boundary rim defines an open space at least at a forefoot support area of the ground-engaging component; and (b) a matrix structure extending at least partially across the open space at least at the forefoot support area to define an open cellular construction with plural open cells in the open space at least at the forefoot support area. A plurality of these open cells of the open cellular construction have openings with curved perimeters and no distinct corners. Additional aspects of this invention relate to ground-engaging components that are very lightweight yet very stiff, particularly in the forefoot support area. Two or more sizes of the ground-engaging components may be provided with substantially constant forefoot stiffness (optionally substantially constant over a size run).

ARTICLE OF FOOTWEAR HAVING A SOLE STRUCTURE WITH A FLUID-FILLED CHAMBER

An article of footwear has an upper and a sole structure secured to the upper. The sole structure includes a chamber that encloses a pressurized fluid. The chamber includes subchambers laterally extending in a medial to lateral direction of the bladder. A bottom surface of the chamber may include at least one bond that laterally extends across the bottom surface of the chamber from one side edge to another side edge of the chamber in the medial to lateral direction. The bond may cooperate with an indentation in the bottom surface that separates one subchamber from an adjacent subchamber. A diameter of the subchambers may decrease in a direction from a heel region of the bladder to a forefoot region of the chamber.

Separable and recyclable footwear

A separable footwear article may comprise an outsole oriented at the bottom of the footwear and configured for ground contact, the outsole comprising a first material; an upper portion releasably coupled to the outsole with thread using chain stitching, the upper portion comprising a second material different from the first material; and an insole removeably disposed adjacent the upper portion and the outsole, the insole comprising a third material different from the first material and the second material; wherein the outsole, the upper portion, and insole are capable of being separated by releasing the thread and hand pulling the thread from the footwear article.
