The process for realizing an upper for shoes consists of using at least a first and second group of needles of a needle-bearing cylinder of a circular knitting machine, each needle of said first group and of said second group of needles being used in a tuck stitch or loop position and/or in a plain drop stitch position and/or in a missed stitch position at least during the forward rotation of said needle-bearing cylinder, said at least first and second group of needles being used alternatively in said at least forward rotation of said needle-bearing cylinder so as to knit several yarns together without having to continuously cut them.

The present invention relates to a seamless foot-covering garment made of knitted courses, a method for manufacturing thereof as well as a respective circular machine for hosiery and knitwear. The foot-covering garment made of knitted courses, comprises a heel portion, a toe portion, a middle portion located between the heel portion and the toe portion and an opening between said heel portion, said middle portion and said toe portion for the insertion of an user's foot. The toe portion and the heel portion are aligned along a longitudinal direction. At said opening the middle portion ends with a right side edge and a left side edge. The garment is seamlessly knitted as a whole. At least one or both the right and left side edges comprise at least one elastic portion made up by a plurality of stretch stitches located at an end of knitted courses. The stretch stitches are composed of at least one main thread of the foot-covering garment knitted with at least one elastic thread. The elastic thread extends with no interruption in said at least one elastic portion, in that it is not cut at each knitted course of said at least one elastic portion.

A sock includes a foot section and a toe section both formed of knitted fabric, the toe section being provided in the form of a bag having a predetermined shape by mutual joining of circumferential edges of the knitted fabric. A knitted portion of the fabric covers a lateral face of the vicinity of a base of the toe section. A big-toe side end edge of fabric covers at least one of the sole portion and instep portion of the toe section and wraps around to the other on the toe base side and a big-toe side join line joining them is located within the plane of the other. The toe section consists of a big toe bag and a four-toe bag. The big-toe bag, which cover the base of the body-center side lateral face of the big toe includes a knitted portion of a knitted fabric is present.
