A method for knitting an integral shoe upper fabric by a circular knitting machine, comprising: knitting from at least one non-elastic yarn by the circular knitting machine to form a first suture reserved section including a first opening; knitting in continuation from an upper edge of the first suture reserved section to form a first toe section; knitting in continuation from the first toe section by turning a knitting direction and combining a lower edge of the first suture reserved section to form a first foot body section, with a first toe turning interknitting line interknitted between the first toe section and the first foot body section; knitting in continuation from a lower edge of the first foot body section to form a first sole extension section; knitting in continuation from the first sole extension section by turning the knitting direction to form a first heel section and a second heel section, with a first heel turning interknitting line interknitted between the first sole extension section and the first heel section; knitting in continuation from the second heel section by turning the knitting direction to form a second sole extension section, with a second heel turning interknitting line interknitted between the second heel section and the second sole extension section and symmetric to the first heel turning interknitting line; knitting in continuation from the second sole extension section to form a second foot body section; knitting in continuation from an upper edge of the second foot body section by turning the knitting direction to form a second toe section, with a second toe turning interknitting line interknitted between the second foot body section and the second toe section; and knitting in continuation from the second toe section and combining a lower edge of the second foot body section to form a second suture reserved section including a second opening, wherein the first opening of the first suture reserved section and the second opening of the second suture reserved section are oriented toward substantially a same direction. knitting from at least one non-elastic yarn by the circular knitting machine to form a first suture reserved section including a first opening; knitting in continuation from an upper edge of the first suture reserved section to form a first toe section; knitting in continuation from the first toe section by turning a knitting direction and combining a lower edge of the first suture reserved section to form a first foot body section, with a first toe turning interknitting line interknitted between the first toe section and the first foot body section; knitting in continuation from a lower edge of the first foot body section to form a first sole extension section; knitting in continuation from the first sole extension section by turning the knitting direction to form a first heel section and a second heel section, with a first heel turning interknitting line interknitted between the first sole extension section and the first heel section; knitting in continuation from the second heel section by turning the knitting direction to form a second sole extension section, with a second heel turning interknitting line interknitted between the second heel section and the second sole extension section and symmetric to the first heel turning interknitting line; knitting in continuation from the second sole extension section to form a second foot body section; knitting in continuation from an upper edge of the second foot body section by turning the knitting direction to form a second toe section, with a second toe turning interknitting line interknitted between the second foot body section and the second toe section; and knitting in continuation from the second toe section and combining a lower edge of the second foot body section to form a second suture reserved section including a second opening, wherein the first opening of the first suture reserved section and the second opening of the second suture reserved section are oriented toward substantially a same direction.
