Abstract

Provided are, among other things, shoes and shoe components, together with systems, methods and techniques for manufacturing the same. One representative embodiment involves a shoe that includes: a sole having a main structure; a strap anchor that has attachment points and is at least partially embedded within the main structure; and a strap that is attached to and/or looped through one or more of such attachment points and that is configured for strapping the shoe to a wearer's foot. Also, in this embodiment, the strap anchor includes a number of strap anchor components attached in a unit, each such strap anchor component including a number of the attachment points and being at least partially embedded within the main structure.

First claim

What is claimed is:

1. A shoe, comprising:
a sole comprised of a base material;
a strap anchor made of a second material that is stronger and more durable than the base material and having: (1) a central elongated section, embedded within the base material of the sole so as to be hidden from view, and extending continuously and longitudinally through a substantial portion of the sole's length, and (2) a plurality of projections, extending laterally from sides of the central elongated section, and providing attachment points on said left and right sides of the shoe; and
a strap that is at least one of attached to and looped through said attachment points and that is configured for strapping the shoe to a wearer's foot.

2. The shoe according to claim 1 , wherein the strap includes an attachment mechanism at its distal end.

3. The shoe according to claim 2 , wherein the attachment mechanism comprises at least one of a high-density-hook mechanism and a high-density-loop mechanism.

4. The shoe according to claim 1 , wherein a front portion of the central elongated section of the strap anchor is at least one of stronger and more rigid than other portions of the strap anchor.

5. The shoe according to claim 1 , wherein said projections are configured as relatively long and narrow arms.

6. The shoe according to claim 1 , wherein a plurality of straps fixedly attach to different ones of the attachment points.

7. The shoe according to claim 1 , wherein the base material has been molded around the central elongated section of the strap anchor.

8. The shoe according to claim 1 , wherein the base material has been blown with air so as to include a plurality of small air pockets that make the base material more cushiony and less dense.

9. The shoe according to claim 8 , wherein the sole is made entirely of the base material.

10. The shoe according to claim 8 , wherein the shoe has a main body structure that, other than the embedded strap anchor, is made entirely of the base material.

11. The shoe according to claim 1 , wherein a plurality of the projections terminate in the attachment points.

12. The shoe according to claim 1 , wherein the central elongated section is relatively long and narrow.

13. The shoe according to claim 1 , further comprising an upper extending above the sole and also made of the base material, and wherein the projections extend up into and are embedded within the upper.

14. The shoe according to claim 1 , wherein the attachment points comprise at least one of loops and slots.

15. The shoe according to claim 1 , wherein the strap anchor is a unitary piece.

16. The shoe according to claim 1 , wherein the attachment points are disposed along an outside perimeter of a top portion of the sole.

17. The shoe according to claim 1 , wherein the attachment points are just slightly above the sole.

18. The shoe according to claim 1 , wherein the attachment points are coated with the base material.

19. The shoe according to claim 1 , wherein the strap anchor is comprised of separate first and second components attached together along the central elongated section.

20. The shoe according to claim 19 , wherein each of the first and second components includes a plurality of the projections, extending laterally from sides of the central elongated section, and providing attachment points on said left and right sides of the shoe.
