A needle-holding element for circular knitting machines, having a structure as a hollow solid of rotation developing around a central axis and configured for rotating and for supporting a plurality of needles moving so as to produce a knitted fabric; the needle-holding element has at least one working surface shaped as a surface of rotation obtained through the rotation of a portion of generating straight line around the central axis; on the working surface a plurality of needle seats is defined, placed one beside the other and arranged circumferentially or radially around the central axis, wherein each needle seat movably houses at least a portion of at least one respective needle. At least one needle seat has at least a first length has a longitudinal development, on the working surface, inclined with respect to the generating straight line.

A bent part of a sock has (i) a bulging part having a first bulging region which includes a region in which the number of wales decreases, and a second bulging region which includes a region in which the number of wales increases and (ii) an extended part having a first extended region in which the number of wales increases, and a second extended region in which the number of wales decreases. The extended part is located so as to be closer to a bend direction side than the bulging part. The extended part has a boundary part between the first extended region and the second extended region which boundary part has a bend direction side first end. The bend direction side first end is located on a center line in a direction in which a width of the sock extends, or within a predetermined distance from the center line.
