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.
