A method for providing intermediate manufactures for the production of manufactures such as an inshoe, footlet, no-show sock, shoes with a circular hosiery knitting machine with a needle cylinder arranged so that its axis is vertical, wherein said needle cylinder has, on its lateral surface, a plurality of axial slots, each of which accommodates a needle, at least one drop or feed being arranged around said needle cylinder and at least one yarn engageable by the needles to form knitting being dispensed thereat, means being provided for the actuation of the needles along the corresponding axial slot in order to grip the yarn at said at least one feed and form loops of knitting, selection devices being provided for selecting the needles to be moved to knit at said at least one feed, said needle cylinder being actuatable with a rotary motion about its own axis with respect to said at least one feed in both directions of rotation in order to form knitting by means of at least part of said needles with said at least one yarn dispensed by said at least one feed, wherein the method comprises at least the following steps: - a step of providing a first tubular portion of knitted fabric by actuating the needle cylinder with a continuous rotary motion about its own axis in one direction of rotation; - a narrowing step, in which a portion of knitted fabric is provided by moving to knit a group of contiguous needles at said at least one feed, actuating the needle cylinder with an alternating rotary motion about its own axis and progressively decreasing the number of needles moved to knit at said at least one feed, excluding, according to a preset sequence, needles located at the lateral ends of said group of needles and retaining, by means of said needles excluded from knitting, the last formed loop of knitting, in order to form first partial rows of knitting; - a widening step, in which a portion of knitted fabric is provided by moving to knit a group of contiguous needles at said at least one feed, actuating the needle cylinder with an alternating rotary motion about its own axis and progressively increasing the number of needles moved to knit at said at least one feed, returning to knit, according to a preset sequence which is the reverse of the sequence of said narrowing step, the needles previously excluded from knitting in said narrowing step, in order to provide second partial rows of knitting joined with said first partial rows of knitting; - a step of providing a second tubular portion of knitted fabric by actuating the needle cylinder with a continuous rotary motion about its own axis in one direction of rotation; in said narrowing step and in said widening step the respective preset sequences, according to which the number of needles of said group of needles moved to knit is first decreased and then increased, being such as to achieve the joining of said first tubular portion and of said second tubular portion with a lateral portion thereof at the loops of knitting, arranged at the ends of said first partial rows of knitting and of said second partial rows of knitting, formed by the needles previously excluded from knitting in said narrowing step and then returned to knit in said widening step, with the axes (2a, 5a) of said two tubular portions (2, 5) forming between them an angle that is substantially less than 90° characterized in that after said narrowing step and before said widening step, a part of said group of needles performs at least two heel knitting processes (E, F) in sequence by means of the actuation with an alternating rotary motion of the needle cylinder about its own axis. - a step of providing a first tubular portion of knitted fabric by actuating the needle cylinder with a continuous rotary motion about its own axis in one direction of rotation; - a narrowing step, in which a portion of knitted fabric is provided by moving to knit a group of contiguous needles at said at least one feed, actuating the needle cylinder with an alternating rotary motion about its own axis and progressively decreasing the number of needles moved to knit at said at least one feed, excluding, according to a preset sequence, needles located at the lateral ends of said group of needles and retaining, by means of said needles excluded from knitting, the last formed loop of knitting, in order to form first partial rows of knitting; - a widening step, in which a portion of knitted fabric is provided by moving to knit a group of contiguous needles at said at least one feed, actuating the needle cylinder with an alternating rotary motion about its own axis and progressively increasing the number of needles moved to knit at said at least one feed, returning to knit, according to a preset sequence which is the reverse of the sequence of said narrowing step, the needles previously excluded from knitting in said narrowing step, in order to provide second partial rows of knitting joined with said first partial rows of knitting; - a step of providing a second tubular portion of knitted fabric by actuating the needle cylinder with a continuous rotary motion about its own axis in one direction of rotation;
