Abstract (en)

A 3D shoe blank (100, 200, 200', 200") is an integral knit fabric without any sewn portion made by a double-bed flat knitting machine and includes an upper portion (112, 212) having two technical surfaces and knitted from at least a first yarn (10) by skip-needle double-knitting, a front sole portion (122, 222) connected to the upper portion (112, 212) by a cast-on line (101, 201) and two connection lines (102, 103; 202, 203) to form a pocket structure, a rear portion (130) connected to the front sole portion (122, 222), and a heel portion (140) extending from a center rear end of the rear portion (100a). A portion of the front sole portion (122, 222) corresponding to the upper portion (112, 212) is knitted from at least a second yarn (20) by skip-needle single-knitting. Two opposite sides of the heel portion (140) are respectively connected to left and right rear ends of the rear portion (130) to form a 3D rear shoe portion (100a) with two joining lines (104a, 104b) formed between the heel portion (140) and the rear portion (130).
