What is claimed is:

1. Sports shoe, a part which extends upwards of a shell at a zone on the inner side and a zone on the outer side relative to a longitudinal center plane;
adjustable hinging means for joining the leg piece to said outwardly extending part of the shell, which define an axis about which the leg-piece is able to perform a flexing movement of controlled amplitude along the center plane, a pair of spaced apart apertures on said upwardly extending part of the shell at each of said inner and outer zones; and
plates on corresponding outer surfaces of the leg piece for allowing selective insertion and subsequent locking of at least one of the hinging means, so that, the said hinging axis may assume at least two different angular positions with respect to the centre plane.
 
2. Sports shoe according to claim 1, characterized in that the hinging means are elongated bodies designed to be inserted, from outside, into through-openings provided on the rigid insertion plates, each of which is able to assume at least two different positions on the outer surface of the leg-piece and ends of which are engageable in one of the apertures provided on the said part of the shell.
 
3. Sports shoe according to claim 2, characterized in that the said rigid insertion plates are designed to assume at least two angularly spaced positions on the outer surface of the leg-piece.
 
4. Sports shoe according to claim 2, characterized in that the said rigid insertion plates are designed to assume at least two linearly spaced positions on the outer surface of the leg-piece.
 
5. Sports shoe according to claim 4, characterized in that, when the said rigid insertion plates are designed to assume at least two linearly spaced positions along the vertical on the outer surface of the leg-piece, adjustment of “canting” is also possible.
 
6. Sports shoe according to any one of the preceding claims, characterized in that the said hinging means are screws and in that their end part is designed to engage in threaded openings fixed to the said upwardly extending part of the shell.
 
7. Sports shoe according to claim 6, characterized in that the said threaded openings are provided on rigid plates fixed to the said upwardly extending part of the shell.
 
8. Sports shoe according to claim 6, characterized in that the said threaded openings consist of flanged and threaded bushes fixed to the said upwardly projecting part of the shell.
