1. A blank (2) for manufacturing a no-show sock by using a fabric, the blank (2) comprising:
a bottom portion (210) having a contour configured to correspond to a sole and configured to define a bottom of the no-show sock;
a front portion (212) having a contour configured to correspond to toes and a front foot top; and
first and second lateral portions (214, 216) configured to surround lateral foot sides and a heel,
the bottom portion (210), the front portion (212), and the first and second lateral portions (214, 216) are made by the fabric and connected integrally,
wherein the front portion (212) is connected to an upper end of the bottom portion (210), and
wherein a boundary line BL on which the bottom portion (210) and the front portion (212) are connected has a predetermined inclination angle θ with respect to a horizontal line HL perpendicular to a central axis CL of the bottom portion (210),
wherein first and second lateral portions (214, 216) are connected to two opposite edges (210a, 210b) of the bottom portion (210), respectively, a lower end of the bottom portion (210) has a contour curved and protruding outward configured to correspond to the heel, and a ninth superimposed portion (229) is formed at a lower end of the bottom portion (210),
wherein a fifth superimposed portion (225) is formed at a lower end of the first lateral portion (214), and a seventh superimposed portion (227) is formed on an inner edge of the first lateral portion (214),
wherein a sixth superimposed portion (226) is formed at a lower end of the second lateral portion (216), and an eighth superimposed portion (228) is formed on an inner edge of the second lateral portion (216),
wherein two opposite edges (212a, 212b) of the front portion have contours respectively corresponding to an upper edge (214a) of the first lateral portion (214) and an upper edge (216b) of the second lateral portion (216),
wherein when the front portion (212) is folded along the boundary line BL relative to the bottom portion (210), the two opposite edges (212a, 212b) of the front portion are aligned with the upper edge (214a) of the first lateral portion (214) and the upper edge (216b) of the second lateral portion (216), respectively and seam-sealed together,
wherein the fifth superimposed portion (225) at the lower end of the first lateral portion (214) and the sixth superimposed portion (226) at the lower end of the second lateral portion (216) overlap each other and are sewn together,
wherein the ninth superimposed portion (229) at the lower end of the bottom portion (210) overlaps with the seventh superimposed portion (227) on an inner edge of the first lateral portion (214) and the eighth superimposed portion (228) on an inner edge of the second lateral portion (216) and is sewn together with them, and
wherein a protrusion (229d) protruding outward along the central axis CL of the bottom portion (210) is formed at a center of the ninth superimposed portion (229) at the lower end of the bottom portion (210).
