Abstract

Footwear includes an inner knitted fabric (5) and an outer knitted fabric (4) that are connected by a stitch row at a top line (6). In the footwear, wale directions of the inner knitted fabric and the outer knitted fabric are different, and/or, the outer knitted fabric is provided with a portion made of a knitted structure (50) with holes, and the inner knitted fabric arranged on the inner side of that portion is made of a knitted structure (60) whose stretchability is lower than that of another portion of the inner knitted fabric. A difference in stretchability between the vertical and horizontal directions of the footwear provided with a double layer knitted fabric is reduced, or a difference in stretchability depending on the position in the footwear is reduced.

Claims

1. Footwear provided with a double layer knitted fabric comprising an inner knitted fabric and an outer knitted fabric connected by a stitch row at a top line,

characterized in that wale directions of the inner knitted fabric and the outer knitted fabric are different, and/or that the outer knitted fabric includes a portion made of a knitted structure with holes and that the inner knitted fabric has a knitted structure at an inner side of said portion with reduced stretchability than other portions of the inner knitted fabric.

2. The footwear provided with a double layer knitted fabric according to claim 1,

characterized in that the wale directions of the inner knitted fabric and the outer knitted fabric are different, and that the outer knitted fabric includes the portion made of the knitted structure with holes, and that the inner knitted fabric has the knitted structure at the inner side of the portion with the reduced stretchability than other portions of the inner knitted fabric.

3. The footwear provided with a double layer knitted fabric according to claim 1,

characterized in that the wale direction of one of the inner knitted fabric and the outer knitted fabric is parallel to a direction connecting a toe and a heel, and the wale direction of the other one is parallel to a direction connecting the top line and a bottom, and

that the inner knitted fabric and the outer knitted fabric are connected by said stitch row at the top line and that the wale directions thereof cross mutually.

4. The footwear provided with a double layer knitted fabric according to claim 1,

characterized in that the inner knitted fabric or the outer knitted fabric is provided with an opening suitable for inserting a coating device for applying an adhesive agent.

5. The footwear provided with a double layer knitted fabric according to claim 1,

characterized in that, at said top line, the outer knitted fabric has a plain knitted structure with face stitches and has the wale direction parallel to a periphery of the top line, that the inner knitted fabric has a plain knitted structure with face stitches and has the wale direction perpendicular to the periphery of the top line, and that the outer knitted fabric and the inner knitted fabric curl inward of the top line.
