Abstract

A footwear system includes an article of footwear that has a sole with a medial side, a lateral side, and a foot-receiving surface. The article of footwear has an upper with a medial side portion and a lateral side portion. The medial side portion is fixed to the medial side of the sole and has a first distal end. The lateral side portion is fixed to the lateral side of the sole and has a second distal end. The medial side portion and the lateral side portion are configured to wrap at least partially around a foot positioned on the foot-receiving surface. The medial side portion is securable at the first distal end, and the lateral side portion is separately securable at the second distal end remote from the medial side portion when the medial side portion and the lateral side portion are wrapped at least partially around the foot.

First claim

The invention claimed is:

1. A footwear system comprising: an article of footwear including: a sole having a medial side, a lateral side, and a foot-receiving surface; an upper having:
a medial side portion that is fixed to the medial side of the sole and has a forward wing with a first distal end;
a lateral side portion that is fixed to the lateral side of the sole and has a forward wing with a second distal end;
a strap fixed at a medial end to a periphery of the sole at the medial side of the sole, and fixed at a lateral end to the periphery of the sole at the lateral side of the sole, the strap spanning across the sole over a foot-receiving surface of the sole at a forefoot portion of the sole; and

a sock; the sock being made of a base portion and multiple fastener portions; the multiple fastener portions disposed above a sole of the sock; and the base portion of the sock extending along the sole of the sock and above the sole of the sock, and surrounding the multiple fastener portions; the multiple fastener portions including a first fastener portion disposed at least partially on a lateral side of the sock, and a second fastener portion disposed at least partially on a medial side of the sock;
wherein:
the forward wing of the medial side portion and the forward wing of the lateral side portion are configured to wrap at least partially around the sock when the sock is worn on a foot slipped under the strap and positioned by a wearer on the foot-receiving surface;
the forward wing of the medial side portion includes a fastener portion fixed to the first distal end;
the forward wing of the lateral side portion includes a fastener portion fixed to the second distal end;
the fastener portion of the forward wing of the medial side portion is securable to the first fastener portion of the sock at the lateral side of the sock when the forward wing of the medial side portion is wrapped at least partially around the sock; and
the fastener portion of the forward wing of the lateral side portion is separately securable to the second fastener portion of the sock at the medial side of the sock when the forward wing of the lateral side portion is wrapped at least partially around the sock without overlapping the forward wing of the medial side portion.

2. The footwear system of claim 1 , wherein: the multiple fastener portions of the sock include a first knit configuration; and the base portion of the sock includes a second knit configuration different from the first knit configuration and knit integrally with the first knit configuration.

3. The footwear system of claim 2 , wherein the first knit configuration is a circular knit with a fusible body yarn having hardened loops.

4. The footwear system of claim 3 , wherein only the first knit configuration includes the fusible body yarn.

5. The footwear system of claim 1 , wherein the first fastener portion and the second fastener portion of the sock are spaced from one another.

6. The footwear system of claim 1 , wherein: the medial side portion has a rearward wing that wraps at least partially rearward around the sock worn on the foot; the lateral side portion has a rearward wing that wraps at least partially rearward around the sock worn on the foot.

7. The footwear system of claim 6 , wherein the multiple fastener portions include a third fastener portion, and the rearward wing of the medial side portion and the rearward wing of the lateral side portion each have an additional fastener portion at least one of which is securable to the third fastener portion of the sock when the medial side portion and the lateral side portion are wrapped at least partially around the sock worn on the foot.

8. The footwear system of claim 7 , wherein one of the rearward wing of the medial side portion and the rearward wing of the lateral side portion crosses over the other of the rearward wing of the medial side portion and the rearward wing of the lateral side portion and secures to said third fastener portion of the sock at a heel region of the sock.

9. The footwear system of claim 5 , wherein: the multiple fastener portions of the sock include a first knit configuration; and the base portion of the sock includes a second knit configuration different from the first knit configuration.

10. The footwear system of claim 5 , wherein: either the fastener portion of the medial side portion and the fastener portion of the lateral side portion include a plurality of hooks and the multiple fastener portions of the sock include a plurality of loops that are securable to the plurality of hooks, or the fastener portion of the medial side portion and the fastener portion of the lateral side portion include a plurality of loops and the multiple fastener portions of the sock include a plurality of hooks that are securable to the plurality of loops of the fastener portion of the medial side portion and the fastener portion of the lateral side portion.

11. The footwear system of claim 1 , wherein the first fastener portion of the sock is larger than the fastener portion of the forward wing of the medial side portion.

12. The footwear system of claim 1 , wherein the second fastener portion of the sock is larger than the fastener portion of the forward wing of the lateral side portion.

13. The footwear system of claim 1 , wherein the strap is a first forefoot strap, and the footwear system further comprising: a second forefoot strap fixed at a medial end to the periphery of the sole at the medial side of the sole, and fixed at a lateral end to the periphery of the sole at the lateral side of the sole, the second forefoot strap spanning across the sole over the foot-receiving surface at the forefoot portion of the sole and crossing over the first forefoot strap.

14. A footwear system comprising: an article of footwear including: a sole having a medial side, a lateral side, and a foot-receiving surface;
an upper having:
a medial side portion that is fixed to the medial side of the sole and has a first distal end;
a lateral side portion that is fixed to the lateral side of the sole and has a second distal end; and a strap fixed at a medial end to a periphery of the sole at the medial side of the sole, and fixed at a lateral end to the periphery of the sole at the lateral side of the sole, the strap spanning across the sole over a foot-receiving surface of the sole at a forefoot portion of the sole; and

a sock; the sock being made of a base portion and multiple fastener portions; the multiple fastener portions disposed above a sole of the sock; and the base portion of the sock extending along the sole of the sock and above the sole of the sock, and surrounding the multiple fastener portions; the multiple fastener portions including a first fastener portion disposed at least partially on a lateral side of the sock, and a second fastener portion disposed at least partially on a medial side of the sock;
wherein:
the medial side portion and the lateral side portion are configured to wrap at least partially around the sock slipped under the strap and positioned by a wearer on the foot-receiving surface; and
the medial side portion is securable at the first distal end, and the lateral side portion is separately securable at the second distal end remote from the medial side portion when the medial side portion and the lateral side portion are wrapped at least partially around the sock.

15. The footwear system of claim 14 , further comprising: the sock configured to be worn on the foot and positioned on the foot-receiving surface of the sole: wherein: the medial side portion includes a fastener portion
