Abstract

Aspects herein are directed to a sock having an integrally knit tab positioned between a collar of the sock and a heel of the sock, where the collar defines an opening for a wearer's foot. The base of the tab is integrally knit with a reciprocally knit section to reinforce the structural integrity of the tab, which may be used to assist the wearer in donning and/or doffing the sock by acting as the primary structure by which the wearer pulls the sock around the wearer's foot when donning the sock.

First claim

What is claimed is:

1. A knit sock comprising:
a collar;
a leg portion extending from the collar, wherein the leg portion comprises:
a first knit course that extends entirely around a circumference of the leg portion;
a set of knit courses comprising a second knit course and a third knit course, the set of knit courses comprising partial length knit courses that extend only partially around the circumference of the leg portion from a medial aspect of the leg portion, around a back aspect of the leg portion, and to a lateral aspect of the leg portion, wherein the second knit course is directly interlooped with the first knit course; and
a fourth knit course that is directly interlooped with the third knit course of the set of knit courses, that is directly interlooped with the first knit course, and that extends entirely around the circumference of the leg portion, wherein the second knit course and the third knit course are interlooped with courses positioned between the first knit course and the fourth knit course;

a heel portion extending from the leg portion; and
a tab located between the collar and the heel portion, the tab directly interlooped with the set of knit courses at the back aspect of the leg portion, wherein:
the set of knit courses and the tab comprise a first yarn that exhibits a greater mechanical stretch than a second yarn used to knit the first course; and
the first yarn does not extend through the heel portion or the first course.

2. The knit sock of claim 1 , wherein the first yarn is a textured yarn.

3. The knit sock of claim 1 , wherein the tab comprises a first base, a second base, and a loop portion extending between the first base and the second base, and wherein the first base and the second base of the tab are directly interlooped with the set of knit courses.

4. The knit sock of claim 1 , wherein the heel portion comprises a first knit segment having partial length knit courses, a second knit segment that extends circumferentially around the knit sock, and a third knit segment having partial length knit courses, the second knit segment positioned between and spacing apart the first knit segment and the third knit segment.

5. The knit sock of claim 4 , the first knit segment is spaced apart from the second knit segment from about 1.3 cm to about 2.3 cm.

6. A knit sock comprising:
a collar;
a leg portion extending from the collar, the leg portion comprising:
a first knit course extending around a circumference of the leg portion;
a set of knit courses comprising a second knit course and a third knit course, the set of knit courses comprising partial length knit courses that extend only partially around the circumference of the leg portion from a medial aspect of the leg portion, around a back aspect of the leg portion, and to a lateral aspect of the leg portion wherein the second knit course is directly interlooped with the first knit course; and
a fourth knit course that is directly interlooped with the third knit course of the set of knit courses, that is directly interlooped with the first knit course, and that extends entirely around the circumference of the leg portion, wherein the second knit course and the third knit course are interlooped with courses positioned between the first knit course and the fourth knit course;

a heel portion extending from the leg portion; and
a tab comprising a first base, a second base, and a loop portion extending between the first base and the second base, the first base and the second base of the tab directly interlooped with courses of the set of knit courses, wherein the tab is located between the collar and the heel portion of the knit sock at the back aspect of the leg portion, wherein:
the set of knit courses and the tab comprise a first yarn that exhibits a greater mechanical stretch than a second yarn used to knit the first course; and
the first yarn does not extend through the heel portion or the first course.

7. The knit sock of claim 6 , wherein the heel portion comprises a first knit segment having partial length knit courses, a second knit segment that extends around a circumference of the knit sock, and a third knit segment having partial length knit courses, the second knit segment positioned between and spacing apart the first knit segment and the third knit segment.

8. The knit sock of claim 7 , wherein the first knit segment is spaced apart from the third knit segment from about 1.3 cm to about 2.3 cm.

9. The knit sock of claim 7 , wherein the first knit segment and the third knit segment comprise 31 knit courses to 41 knit courses.

10. The knit sock of claim 7 , wherein, the second knit segment comprises 15 knit courses to 27 knit courses.

11. The knit sock of claim 7 , wherein an angle formed between the leg portion and a foot portion of the knit sock is greater than 130 degrees and less than 150 degrees.
