20090288451 | Socks - An object of the present invention is to provide a sock which offers a fit, and does not cause fatigue, blood congestion, or the like if worn for a long period of time. The sock has a length from a toe to at least an ankle, and is knitted from a knitting yarn. The sock has a base knit structure knitted at an inside half region of an arch part of the sole from an upper thread and under thread, and has an auxiliary thread further inserted together with the upper thread, so as to form a knitted part which is contracted and reduced in extensibility. | 11-26-2009 |
