Knit sock with targeted compression zone
A knit sock includes a foot portion having an upper instep area and a lower sole area integrally knit of a body yarn in circumferential courses and axial wales. The lower sole area defines inner and outer arch regions. The inner arch region incorporates a targeted compression zone adapted to reside generally adjacent an inner arch of a wearer's foot. The compression zone includes axially extending compression ridges of variable length spaced apart from a top of the compression zone to a bottom of the compression zone. When the sock is worn, a compression force applied by the foot portion within the targeted compression zone is greater than the compression force in directly adjacent areas of said foot portion.
1. A knit sock, comprising:
a foot portion comprising a heel;
a targeted compression zone formed with said sock, and comprising axially extending compression ridges spaced-apart from each other and extending axially from a first end of said compression zone proximate said heel to a second end of said compression zone, and wherein adjacent ones of said compression ridges have different coursewise termination points at the second end of said compression zone, and wherein said targeted compression zone extends in a coursewise direction to occupy only a partial circumferential portion of said sock, thereby exerting an intensified targeted compression force at a predetermined point on a wearer; and
whereby the compression force applied by said sock within said targeted compression zone is greater than the compression force in directly adjacent areas of said sock.
2. The knit sock according to claim 1 , wherein said targeted compression zone comprises elastic yarns laid-in said body yarn.
3. The knit sock according to claim 1 , wherein said axially extending compression ridges comprise individual uncut pattern yarns.
4. The knit sock according to claim 1 , wherein said targeted compression zone is semi-circular.
5. The knit sock according to claim 4 , wherein a first side of said targeted compression zone is substantially arcuate, and wherein a second side of said targeted compression zone is substantially linear.
6. The knit sock according to claim 5 , wherein said compression ridges taper in respective axial length from the linear side of said compression zone to the arcuate side of said compression zone.
7. The knit sock according to claim 6 , wherein the arcuate side of said compression zone faces a bottom axial centerline of said foot portion.
8. The knit sock according to claim 7 , wherein the linear side of said compression zone extends adjacent an inside axial centerline of said foot portion.
9. The knit sock according to claim 1 , wherein said compression ridges shorten in respective axial lengths from the first end of said compression zone to the second end of said compression zone.
10. The knit sock according to claim 1 , wherein said compression zone comprises double covered elastic yarns.
11. The knit sock according to claim 1 , wherein said compression zone has an increased density as compared to directly adjacent areas of said sock.
12. The knit sock according to claim 1 , wherein said targeted compression zone has reduced coursewise and walewise stretchability relative to directly adjacent areas of said sock.
13. A knit sock integrally knit of a body yarn in circumferential courses and axial wales, and comprising:
a foot portion and an ankle portion, said foot portion comprising a heel;
a targeted compression zone formed with said sock, and comprising axially extending compression ridges spaced-apart from each other and extending axially from a first end of said compression zone proximate said heel to a second end of said compression zone, and each compression ridge comprising at least one pattern yarn knit with the body yarn, and wherein adjacent ones of said compression ridges have different coursewise termination points at the second end of said compression zone, and wherein said targeted compression zone extends in a coursewise direction to occupy only a partial circumferential portion of said sock, thereby exerting an intensified targeted compression force at a predetermined point on a wearer; and
whereby the compression force applied by said sock within said targeted compression zone is greater than the compression force in directly adjacent areas of said sock.
14. The knit sock according to claim 13 , wherein said targeted compression zone comprises elastic yarns laid-in said body yarn.
15. The knit sock according to claim 13 , wherein said targeted compression zone comprises double covered elastic yarns.
16. The knit sock according to claim 13 , wherein said targeted compression zone has an increased density as compared to directly adjacent areas of said sock.
17. The knit sock according to claim 13 , wherein said targeted compression zone has reduced coursewise and walewise stretchability relative to directly adjacent areas of said sock.
18. The knit sock according to claim 13 , wherein said targeted compression zone comprises greater than 3 axially extending compression ridges.
