Presented are footwear sole structures with foot-cushioning insoles movably mounted onto impact-attenuating midsoles, methods for making/using such sole structures, and footwear fabricated with such sole structures. A multilayered sole structure assembly includes an insole movably mounted on a midsole. The midsole is formed with a first compressible material and includes opposing upper and lower midsole surfaces, multiple protrusions projecting from the upper midsole surface, and multiple pockets recessed into the upper midsole surface and interleaved with the midsole protrusions. The insole, which is formed with a second compressible material distinct from the first compressible material, includes opposing upper and lower insole surfaces, multiple protrusions projecting from the lower insole surface and interleaved with the midsole protrusions, and multiple pockets recessed into the lower insole surface and interleaved with the insole protrusions. Each midsole protrusion nests within a respective insole pocket, while each insole protrusion nests within a respective midsole pocket.

A shoe includes: an upper member containing a knit fabric, a knit-like fabric, and/or a woven fabric as a primary member and forming a part of a medial side surface, a part of a lateral side surface, and a part of a back surface; an outsole member made of thermoplastic resin and forming a bottom portion including a contact surface, and a peripheral portion attached at least partially to respective lower parts of the medial and lateral side surfaces and a lower part of the back surface and connected to the bottom portion; and a sock liner inserted in interior space defined by the upper member and the outsole member. The upper member defines an opening at which at least a part of the lateral side surface is cut. The outsole member includes a window portion covering the opening. The window portion is made of a semi-transparent material that makes at least a part of a lateral side surface of the sock liner in the interior space visible through the window portion covering the opening.

METHOD AND SYSTEM FOR AUTOMATICALLY MANUFACTURING SHOES

Described are a method and a system for automatically manufacturing shoes. The method includes automatically manufacturing a plurality of soles in a first station and automatically manufacturing a plurality of uppers in a second station, wherein the first and the second station are operating in parallel and are arranged in a common facility so that a manufactured sole and a manufactured upper can be transported to a joining station and be automatically joined there.

ARTICLE OF FOOTWEAR AND METHOD OF MANUFACTURING AN ARTICLE OF FOOTWEAR
20210392998 · 2021-12-23 · ·

An article of footwear includes an upper and a strobel stitched to the upper at a series of stitches disposed in stitch holes that extend through the strobel. The strobel and the upper define a foot-receiving cavity with an inner surface of the strobel disposed at the foot-receiving cavity. A midsole is secured to the upper and an outer surface of the strobel is disposed at the midsole. The stitch holes are obstructed such that the stitch holes are not exposed to both the midsole and the foot-receiving cavity. Accordingly, when a flowable polymeric material is injected in a mold cavity to form the midsole with the lower portion of the upper and the strobel in the mold cavity, the stitch holes will not provide a path for entry of the flowable polymeric material into the foot-receiving cavity. A method of manufacturing an article of footwear is disclosed.
