Easy don and doff sock
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 tab may comprise a loop with an opening being open in a medial-to-lateral direction. 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. The heel portion may have first and second integrally knit sections comprising partial-length courses.
1. A knit sock comprising:
a collar;
a heel portion;
a leg portion extending from the collar and to the heel portion, wherein the leg portion comprises:
a first knit course that extends entirely around a circumference of the leg portion;
an integrally knit pull loop that is between the collar and the heel portion at a back aspect of the leg portion and that comprises a second set of knit courses that are integrally knit with the first knit course, such that a course of the second set of knit courses is directly interlooped with the first knit course, wherein:
the integrally knit pull loop comprises:
a first tab base and a second tab base, which are integrally knit with the leg portion, and
a loop portion that comprises a loop extending between the first tab base and the second tab base;
wherein the loop portion comprises an opening that is open in a medial-to-lateral direction; and the second set of knit courses and the integrally knit pull loop comprise a first yarn that exhibits a greater mechanical stretch than a second yarn used to knit the first knit course.
2. 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.
