## Abstract

A sock (1) comprises a heel part (H) between a tubular leg part (L) and a tubular sole part (S), which comprises mesh-number varying regions (V1-V6) arranged along a knitting axis (K), and tubular regions (C1-C5) arranged between the mesh-number varying regions. The mesh-number varying regions include an upper region (V1), a lower region (V6), and intermediate regions (V2-V5). The number of courses of the upper region (CV1) is smaller than the number of courses of the lower region (CV6) and the number of courses of the intermediate regions (CV2-CV5). The mesh-number varying regions are constituted by mesh-number increasing regions (V1, V3, V5) and mesh-number reducing regions (V2, V4, V6) alternatingly arranged along the knitting axis. The number of courses of the tubular regions (CC1-CC5) is smaller than the number of courses of the mesh-number varying regions (CV1-CV6).

## Claims

### Claim 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.

### Claim 2 (depends on 1)

The sock according to claim 1, wherein the upper mesh-number varying region is constituted by a mesh-number increasing region and the lower mesh-number varying region is constituted by a mesh-number reducing region.

### Claim 3 (depends on 1)

The sock according to claim 1, wherein the number of the mesh-number varying regions is six and the number of the tubular regions is five, or the number of the mesh-number varying regions is eight and the number of the tubular regions is seven.

### Claim 4 (depends on 2)

The sock according to claim 2, wherein the number of the mesh-number varying regions is six and the number of the tubular regions is five, or the number of the mesh-number varying regions is eight and the number of the tubular regions is seven.
