Strobel lasted injected footwear
First Claim
1. A footwear article comprising:
- a footwear-structure bag encompassing an injected filler material, the footwear-structure bag forming an integrated footwear component, where the injected filler material is an injected foam;
a strobel sock of the footwear-structure bag that is made of a first material, the strobel sock forming an insole region of the footwear-structure bag, where the strobel sock is coupled to a second material of the footwear-structure bag by a stitched junction at the insole region that directly attaches the first material of the strobel sock to the second material of the footwear-structure bag, where the first material of the strobel sock is a highly stretchable material, and where the second material of the footwear-structure bag is a minimally stretching material that is different than the first material of the strobel sock; and
an outsole directly coupled to the footwear-structure bag forming a base of the footwear article,wherein the stitched junction is a stitch and turn seam including stitches, and wherein the stitches are located within an interior of the footwear-structure bag, encompassed by the injected foam.

Abstract
Port-injection footwear is provided. In one example, port-injection footwear is provided including a footwear-structure bag encompassing an injected filler material, such as foam. A strobel sock made of stretchable material may be integrated into an insole region of the footwear-structure bag. The port-injection footwear further may include a foam barrier disposed adjacent to the footwear-structure bag to retain the injected foam within the bag during injection. An outsole may be directly coupled to the footwear-structure bag forming a base of the footwear article. In other examples, the port-injection footwear may include a footwear-structure bag having an injection port, an injected foam retained in the footwear-structure bag, where the injected foam was injected through the injection port, and a port cap positioned at the injection port of the footwear-structure bag.

13. A footwear article comprising:
-
a footwear-structure bag defining a hollow interior cavity, the footwear-structure bag forming an integrated footwear component; a foam injected into the hollow interior cavity of the footwear-structure bag via an injection port integrally formed on the footwear-structure bag, where the footwear-structure bag includes a body and a strobel sock portion, wherein the strobel sock portion is made of a 4-way stretch material that is highly stretchable, where the strobel sock portion forms an insole region of the footwear-structure bag and is integrated into the footwear-structure bag via a stitched junction at the insole region which joins the body directly to the strobel sock portion, where the body of the footwear-structure bag comprises a body material that is minimally stretching, the material of the body being less stretchable than the highly stretchable, 4-way stretch material of the strobel sock portion, and where the body material is different than the 4-way stretch material of the strobel sock portion; a lining fabric coupled to an internally facing surface of the footwear-structure bag; and an outsole directly coupled to the footwear-structure bag forming a base of the footwear article, wherein the stitched junction is a stitch and turn seam including stitches, and wherein the stitches are located within an interior of the footwear-structure bag, encompassed by the injected foam. - View Dependent Claims (14, 15)
