Abstract:
1. A knit sock, comprising: 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, said lower sole area defining inner and outer arch regions; said inner arch region comprising a targeted compression zone adapted to reside adjacent an inner arch of a wearer's foot, and said compression zone comprising axially extending compression ridges of variable length spaced-apart from a top of said compression zone to a bottom of said compression zone; and wherein said targeted compression zone is generally semi-circular, and has a substantially arcuate side at the bottom of said compression zone and extending adjacent a bottom axial centerline of said foot portion, and a substantially linear side at the top of said compression zone and extending adjacent an inside axial centerline of said foot portion, and wherein said compression ridges taper in respective axial length from the linear side at the top of said compression zone towards the arcuate side at the bottom of said compression zone; whereby a compression force applied by said foot portion within said targeted compression zone is greater than the compression force in directly adjacent areas of said foot portion.
