Socks and production method of same

Abstract

Improved sock or similar garment for preventing leg alignment problems is disclosed. The improved sock or similar garment has a structural region having an inelastic region woven together into a structure having a strong elastic intensity. When worn, the region forms a heel constricting band so as to join an area near a tip of the calcaneal tuberosity with a superior portion of the talus, wherein the heel constricting band divides the structure of the heel region in two.

1 . A sock or a similar garment comprising:
 a heel region covering the calcaneal tuberosity including a plurality of structural regions, each of which region having a different elastic intensity;   one of the structural regions being an inelastic region woven together into a structure having a strong elastic intensity, wherein an inelastic region forms a heel constructing band woven so as to pass by an area near a tip of the calcaneal tuberosity and a superior portion of the talus, when worn, and divides the structure of the heel region in two.   
     
     
         2 . A sock or a similar garment comprising:
 a heel region covering the calcaneal tuberosity including a plurality of structural regions, each of which region having a different elastic intensity;   one of the structural regions being an inelastic region woven together into a structure having a strong elastic intensity, wherein the inelastic region forms a heel constructing band woven so as to pass by an area near a tip of the calcaneal tuberosity and a superior portion of the talus, when worn, and so divides the structure of the heel region in two,   an upper heel constricting band woven so as to pass by medial and lateral malleoli and the superior portion of a talus, wherein the upper heel constricting band being an inelastic region woven together into a structure having a strong elastic intensity, and   a lower heel constricting band woven so as to pass by an inferior end of the calcaneum near the toes and the superior portion of the talus, wherein the lower heel constricting band being an inelastic region woven together into a structure having a strong elastic intensity.   
     
     
         3 . A method for manufacturing the sock or similar garment according to  claim 1 , comprising the steps, forming by a circular knitting machine, of:
 forming, by using reverse rotating knitting and a gradual reduction in stitches, an ankle-side heel region divided in two by the heel constricting band, the ankle-side heel region being formed as a region for adjusting the angle of the heel constricting band;   forming the heel constricting band by using forward rotating knitting while inserting a yarn having a strong elastic intensity; and   forming, by using reverse rotating knitting and a gradual increase in stitches, a toe-side heel region divided in two by the heel constricting band, the toe-side heel region formed as a region for adjusting the angle of the heel constricting band.   
     
     
         4 . A method for manufacturing the sock or similar garment according to  claim 2 , comprising the steps, forming by a circular knitting machine, of:
 forming the upper heel constricting band by using forward rotating knitting while inserting a yarn having a strong elastic intensity;   forming, by using reverse rotating knitting and a gradual reduction in stitches, an ankle-side heel region divided in two by the heel constricting band, the ankle-side heel region being formed as a region for adjusting the angle of the heel constricting band;   forming the heel constricting band by using forward rotating knitting while inserting a yarn having a strong elastic intensity;   forming, by using reverse rotating knitting and a gradual increase in stitches, a toe-side heel region divided in two by the heel constricting band, the toe-side heel region formed as a region for adjusting the angle of the heel constricting band; and   forming the lower heel constricting band by using forward rotating knitting while inserting a yarn having a strong elastic intensity.
