         8 . The knitted sock according to  claim 1 , wherein the knitted trapezoidal plantar part and the knitted trapezoidal dorsal part together form a pocket of substantially trapezoidal shape, arranged to receive at least partly the toes of a foot, and at least partly the midfoot region of the foot. 
     
     
         9 . The knitted sock according to  claim 1 , wherein the knitted trapezoidal dorsal part comprises a distal part and a proximal part, and wherein the number of stitches (a d ) in a row of stitches of the distal part is smaller than the number of stitches (b d ) in a row of stitches of the proximal part ( 26   a ). 
     
     
         10 . The knitted sock according to  claim 1 , wherein the number of stitches (k) of any row of stitches (n) knitted in the knitted trapezoidal dorsal part is greater than or equal to the number of stitches (p) in the row of stitches (n+2) knitted after the row of stitches (n) and wherein said knitted trapezoidal dorsal part ( 20 ), the numbers n, p and k being integers other than 0. 
     
     
         11 . The knitted sock according to  claim 1 , wherein the knitted trapezoidal dorsal part and the knitted trapezoidal plantar part are symmetrical along a transverse axis of symmetry (T 1 ) passing between the distal end of the knitted trapezoidal dorsal part and the distal end of the knitted trapezoidal plantar part. 
     
     
         12 . The knitted sock according to  claim 1 , wherein the knitted sock comprises a knitted trapezoidal lower heel part and a knitted trapezoidal upper heel part which are joined by knitted auxiliary medial and lateral securing regions. 
     
     
         13 . The knitted sock according to  claim 1 , wherein the knitted sock comprises at least one portion knitted with rows of circular stitches, and wherein said knitted portion extends in the midfoot region of the knitted sock. 
     
     
         14 . The knitted sock according to  claim 1 , wherein the knitted trapezoidal plantar and dorsal parts comprise at most 16% by mass of one or more elastomeric yarn(s). 
     
     
         15 . A method for knitting a knitted sock comprising a toe region, a midfoot region and a heel region, wherein said method comprises:
 a step of knitting B a trapezoidal dorsal or plantar part by progressively decreasing the number of knitted stitches per row(s) of stitches;   a step C of knitting a trapezoidal plantar or dorsal part from the distal end of the knitted trapezoidal dorsal or plantar part by progressively increasing the number of knitted stitches per row(s) of stitches;   a step D of knitting a lateral securing region and a medial securing region which secure the knitted trapezoidal dorsal and plantar parts along their respective lateral and medial edges, the knitting D of said lateral and medial securing regions being carried out progressively during the knitting step C;   wherein the knitted trapezoidal dorsal and plantar parts and said knitted medial and lateral securing regions are knitted so as to extend in the toe region and at least partly in the midfoot region of the knitted sock;   and wherein said method comprises a step A of knitting an aperture opening out into the foot-receiving volume of the sock.
