  • the capital letters added to the black arrows correspond to the letters shown in FIGS. 2 and 3 , which will be referenced in a later description of a footwear knitting method.
  • Knitting yarn for knitting the base knitted fabric portion 2 and the additional knitted fabric portion 3 is not particularly limited, and in this example, knitting yarn that contains thermal fusion yarn is used to knit both portions 2 and 3. Knitting yarn containing thermal fusion yarn allows the footwear 1 to be molded in a desired shape as a result of the footwear 1 being fitted into a shoe last and subjected to thermal treatment.
  • the base knitted fabric portion 2 and the additional knitted fabric portion 3 are fixed so as not to be shifted in position with respect to each other. Both portions 2 and 3 may be fixed to each other by adhesion using thermal fusion yarn, adhesion using an adhesive agent, or sewing. Both adhesion and sewing may also of course be used to fix the portions 2 and 3 to each other.
  • FIGS. 2 An example of a method for knitting the footwear 1 will be described with reference to the schematic diagrams in FIGS. 2 .
  • letters are added to positions that are essential for knitting the footwear 1.
  • thick arrows indicate the directions in which knitting proceeds (the directions are the same as the orientation of stitches).
  • the flat knitting machine used in knitting may be a two-bed flat knitting machine that includes a front needle bed and a back needle bed, and in which a stitch can be transferred between the front and the back needle beds.
  • a flat knitting machine, such as a four-bed flat knitting machine, other than the two-bed flat knitting machine may also of course be used to knit the footwear 1.
  • knitting of the base knitted fabric portion 2 is started from the toe side of the base knitted fabric portion 2, and the knitting is performed until a part of the opening 5 is formed.
  • the part, on the front side of the drawing, of the base knitted fabric portion 2 corresponds to the right side part of the base knitted fabric portion 2
  • the part, on the rear side of the drawing, of the base knitted fabric portion 2 corresponds to the left side part of the base knitted fabric portion.
  • the right side part is knitted with the front needle bed of the flat knitting machine, and the left side part is knitted with the back needle bed.
  • a line E-F-H of an end part, in the wale direction, of the base knitted fabric portion 2 is held on the front needle bed, and a line E-G-H is held on the back needle bed.
  • the additional knitted fabric portion 3 that is bag-shaped with one end open and the other end closed is also knitted as shown in FIG. 2 (A) .
  • the additional knitted fabric portion 3 of this example is knitted into the shape of a bag whose starting end is closed.
  • the starting end of the additional knitted fabric portion 3 is arranged on the toe side of the footwear 1 shown in FIG. 1 , and thus it is preferable to gradually increase the knitting width of the additional knitted fabric portion 3 from the starting end to the termination end.
  • a line A-B-D of the additional knitted fabric portion 3 is held on the front needle bed, and a line A-C-D is held on the back needle bed. Knitting of the additional knitted fabric portion 3 may be performed before or during the knitting of the base knitted fabric portion 2.
