ABSTRACT:
The present invention relates to double-layered socks with inner and outer layers for warmth preservation and exercise. The double-layered socks according to the invention are formed by knitting the starting part (1) corresponding to the toe tip of the inner layer (10) at first, then the toe part (2), sole part (3), heel part (4) and ankle part (5) in that order, and then continuously knitting the ankle part (5′), heel part (4′), sole part (3′), toe part (2′) and finishing part (1′) belonging to the outer layer (20) in succession. Then, the inner layer (10) is arranged to be confronted with the outer layer (20) so as to knit the starting part (1) of the inner layer (10) together with the finishing part (1′) of the outer layer (20) to join them. Finally, the inner and outer layers (10, 20) are sutured at the toe part (2′) of the outer layer (20) to leave a single suturing line (7). Accordingly, the thickness of the suturing seams in the socks is remarkably reduced, so that the suppression or friction by the uppers of shoes on the toe areas of wearers can be removed when shoes together with such inventive socks are put on. The method for manufacturing the inventive socks is simpler and requires less labor and time compared to the conventional ones, whereby the production efficiency is raised.
