An upper for an article of footwear and a method of manufacturing the upper for an article of footwear are disclosed. The upper incorporates a textile element with edges that are joined together to define at least a portion of a void for receiving a foot. The joined edges form a plurality of seams within the textile element, including a longitudinal seam extending on the lower region of the upper from a heel region to a forefoot region. Various warp knitting or weft knitting processes, including circular knitting, may be utilized to form the textile element.

A shoe embryo tailored from a tubular fabric is provided. The shoe embryo includes a sole portion, a toe cap portion located at one end of the sole portion, a heel portion located at the other end of the sole portion, and an ankle portion located above the sole portion and near the heel portion. The ankle portion includes an ankle opening overlock line formed by trimming the tubular fabric and overlocking. The heel portion includes a heel overlock line formed by trimming the tubular fabric and overlocking, and a sole overlock line formed by folding below the heel overlock line and overlocking. The toe cap portion includes a toe cap overlock line formed by trimming the tubular fabric and overlocking.

An apparatus for manufacturing footwear, the apparatus including a jig and a cutting die. The jig including a base member and a plurality of pins, the jig having an outline conforming to an entire outline of a conventional midsole of an article of footwear and having an upwardly facing top surface configured to engage a foam midsole member, and the plurality of pins positioned about a periphery of the base member and projecting upwardly. The cutting die having a plurality of blades configured to form sipes in the lower surface of the foam midsole member, the cutting die being movable toward the top surface of the base member to bring the blades into contact with the foam midsole member disposed between the cutting die and the base member.

An article of footwear and a method of manufacturing the article of footwear are disclosed. The footwear may include an upper and a sole structure. The upper incorporates a textile element with edges that are joined together to define at least a portion of a void for receiving a foot. The textile element may also have a first area and a second area with a unitary construction with varying stitch configurations. The upper may also incorporate longitudinal ribs extending along the lateral and/or medial sides of the upper. Various warp knitting or weft knitting processes, including circular knitting, may be utilized to form the textile element.

A process for manufacturing a waterproof and vapor-permeable shoe is provided. In the process, an adhesive layer is provided on a knitted fabric to form a laminate, and a shoe upper unit is formed from the laminate, and has an adhesive component defining an inner space of the shoe upper unit. A shoe lining member, which is worn on a last, is placed into the shoe upper unit to permit a knitted component of the shoe upper unit to be bonded to the shoe lining member through the adhesive component under a heating treatment.
