Sock

Abstract

A sock that is less likely to slip off and provide an excellent wearing feeling while ensuring a state of the sock being hard to see. This sock provides a foot connecting portion 14 between a toe portion 11 and a heel portion 12. The sock also provides an ankle connecting portion 15 between the heel portion 12 and a body portion 13. The foot connecting portion 14 and the ankle connecting portion 15 that sandwich the heel portion 12 are knitted as non-cylindrical knitted fabrics having predetermined knitting widths, respectively, to form an opening 16 surrounded by the toe portion 11, the foot connecting portion 14, the heel portion 12, the ankle connecting portion 15, and the body portion 13 to open an area from the ankle to the instep in a worn state. This prevents an instep portion of the sock from protruding from a shoe and becoming visible.

1 . A sock that is integrally knitted as a whole with a circular knitting machine and has at least a toe portion covering a toe of a foot, a heel portion covering a heel of the foot, and a body portion cylindrically surrounding a lower leg of a leg, the sock comprising:
 a non-cylindrical foot connecting portion that is knitted between the toe portion and the heel portion and integrally connects the toe portion and the heel portion; and   a non-cylindrical ankle connecting portion that is knitted between the heel portion and the body portion and integrally connects the heel portion and the body portion, wherein   the foot connecting portion is knitted between the toe portion and the heel portion as a knitted fabric having a predetermined knitting width located on a sole side in a worn state,   the ankle connecting portion is knitted between the heel portion and the body portion as a knitted fabric having a predetermined knitting width located on a back side of an ankle in the worn state, and   a predetermined opening surrounded by the toe portion, the foot connecting portion, the heel portion, the ankle connecting portion, and the body portion is formed as an arrangement that opens a predetermined area on a front side of the foot from the ankle to an instep in the worn state.   
     
     
         2 . The sock according to  claim 1 , wherein the ankle connecting portion is knitted with a width dimension such that the ankle connecting portion is hidden behind the ankle and invisible from a front side of the foot in the worn state. 
     
     
         3 . The sock according to  claim 2 , wherein the ankle connecting portion is knitted in a different knitting method from that for a knitted fabric of the other portions of the sock as the knitted fabric that causes a stronger elastic contraction force in a course direction, and is in a state of the knitted fabric being more shrunk in the course direction with respect to the other portions of the sock. 
     
     
         4 . The sock according to  claim 2 , wherein
 the toe portion, the foot connecting portion, the heel portion, the ankle connecting portion, and the body portion are knitted to include at least one continuous common yarn in their knitted fabrics, and   the ankle connecting portion is knitted by inserting a predetermined insertion yarn having larger elasticity than that of the common yarn while continuously inserting the insertion yarn in a course direction, and more shrinks in the course direction by an elastic force of the insertion yarn compared to other portions of the sock.
