1. A sock formed by circular knitting or flat knitting along a knitting axis, the sock comprising:
a leg part;
a sole part; and
a heel part between the leg part and the sole part, the heel part comprising:
a plurality of mesh-number varying regions arranged along the knitting axis, wherein each of the plurality of mesh-number varying regions is defined as only a mesh-number increasing region or a mesh-number decreasing region, and wherein the mesh-number increasing regions and the mesh-number decreasing regions are alternatingly arranged along the knitting axis;
a plurality of tubular regions arranged such that each one of the plurality of tubular regions is interposed with a corresponding pair of the alternating mesh-number increasing regions and the mesh-number decreasing regions, the plurality of tubular regions including first ones and second ones, such that each of the first ones have a leg side edge abutting the mesh-number increasing region and a sole side edge abutting the mesh-number decreasing region, and each of the second ones have a leg side edge abutting the mesh-number decreasing region and a sole side edge abutting the mesh-number increasing region, and
the plurality of mesh-number varying regions further including:
an upper mesh-number varying region connected to a lower edge of the leg part;
a lower mesh-number varying region connected to an upper edge of the sole part; and
a plurality of intermediate mesh-number varying regions between the upper mesh-number varying region and the lower mesh-number varying region,
wherein the number of courses of the upper mesh-number varying region is smaller than each of the number of courses of the lower mesh-number varying region and the number of courses of the intermediate mesh-number varying regions, and
wherein the number of courses of the tubular regions is smaller than the number of courses of the mesh-number varying regions.
