  • the sole section 1d is provided with the supporting section 4c, whereby a wearer naturally performs three-point walking and can really feel that the foot comes into contact with the ground in the order from the heel to the outer portion of the foot and from the little toe to the big toe, so that the walking posture of the wearer is improved. Accordingly, the muscle of the back of a wearer is stretched and knee pain or waist pain is also relieved.
  • the sock 10 is provided with the first buffer section 4b which is knitted at the boundary between the body section 2 and the heel section 1a, whereby it is possible to relieve pain by suppressing tightening on the Achilles' tendon of a wearer while maintaining the tightening force on the ankle by the figure eight section 4.
  • the holding section 4a is provided with the wrinkle suppressing section 4d, whereby it is possible to prevent occurrence of wrinkles in the bent portion, thereby preventing occurrence of pain due to a pinch or the like of the skin of a wearer by wrinkles.
  • the operation and effects are obtained which can contribute to impact absorption in the initial stage of the stance phase and a propulsive force over a stage from the intermediate stage to the late stage of the stance phase and also allows the stability of the foot joint to be obtained by the left and right (varus and valgus) braking.
  • the operation and effects are obtained in which the sock 10 assists the foot joint of a wearer, whereby Achilles' tendon pain, the fatigue and pain of the triceps surae muscle, and the pain of the outside (the ligament) of the foot joint can be relieved.
  • Fig. 6(a) is a front view showing the schematic configuration of a sock related to the second embodiment
  • Fig. 6(b) is a back view of the sock shown in Fig. 6(a)

  • Fig. 7(e) is a plan view of the sock shown in Fig. 7(a)
  • Fig. 7(f) is a bottom view of the sock shown in Fig. 7(a) .
  • the same symbols as those in Figs. 1 to 3 denote the same or equivalent sections, and explanation thereof is omitted.
  • the holding section 4a is provided with an approximately trapezoidal second buffer section 4e which is knitted in different knitting on the tiptoe section 1b side of the sock 10 such that the stretch resistance in the length direction L of the sock 10 in an area knitted in the different knitting is smaller than the stretch resistance of the other area in the holding section 4a.
  • the holding section 4a is provided with an approximately trapezoidal third buffer section 4f which is knitted in different knitting on the cuff section 3 (the flexible section 5) side of the sock 10 such that the stretch resistance in the length direction L of the sock 10 in an area knitted in the different knitting is smaller than the stretch resistance of the other area in the holding section 4a.
  • the other area in the holding section 4a is the moss stitch-insert stitch knitted fabric excluding the wrinkle suppressing section 4d, the second buffer section 4e, and the third buffer section 4f.
  • the second buffer section 4e and the third buffer section 4f are set to be mesh stitch knitted fabrics.
  • the holding section 4a be the moss stitch-insert stitch knitted fabric
  • making the supporting section 4c be the rib stitch-plating stitch-insert stitch knitted fabric
  • making the second buffer section 4e and the third buffer section 4f be the mesh stitch knitted fabrics
  • the holding section 4a and the supporting section 4c have such a magnitude relation of F L4c >F L4a >F L4e ⁇ F L4f that they have a strong tightening force in the length direction L of the sock 10, compared to the second buffer section 4e and the third buffer section 4f.
  • the second embodiment is different from the first embodiment only in that the second buffer section 4e and the third buffer section 4f are newly disposed at the holding section 4a, and the same operation and effects as those in the first embodiment except the operation and effects by the second buffer section 4e and the third buffer section 4f, which will be described later, are obtained.
  • the second buffer section 4e weakens a tightening force on the tiptoe section 1b side on the holding section 4a in the instep section 1c, thereby making a force of pushing the plantar arch of a wearer up by the sole section 1d act obliquely upward on the tiptoe section 1b side, rather than vertically upward with respect to the sole section 1d, and suppresses landing of the tiptoe of the wearer at an acute angle with respect to the ground, thereby being able to prevent a misstep during walking of the wearer.
  • the third buffer section 4f weakens a tightening force on the holding section 4a on the front face side of the body section 2 and makes the holding section 4a and the supporting section 4c not go around the tubular knitted fabric on the flexible section 5 side, thereby suppressing tightening on the Achilles' tendon of a wearer while maintaining a tightening force on the ankle by the figure eight section 4, so that it is possible to relieve pain.
  • the second buffer section 4e and the third buffer section 4f have the operation and effects of emphasizing contrast between the strength and the weakness of the knitted fabrics of the holding section 4a and the supporting section 4c which are adjacent to the second buffer section 4e and the third buffer section 4f, thereby making a wearer further realize a taping effect by the figure eight section 4.
