1 . Sports and/or orthopaedic footwear comprising:
 an insole,   an upper formed by a top-upper part and a bottom-upper part joined to the insole,   a device for relative articulation of the insole/upper, said articulation device comprising:
 a first ring which has a first bottom-upper front arm and a second bottom-upper rear arm which are joined to said bottom upper, wherein said first ring has two diametrically opposite, radial, inner seats for receiving a respective pin with female thread; 
 second ring which has an arm adapted to be fixed to the top upper, wherein said second ring has at least two diametrically opposite eyelets extending over a predefined annular section of the circumference of the ring itself; 
 an anti-friction annular body arranged between said first ring and second ring, wherein the annular body has two diametrically opposite holes with a diameter such as to allow a respective pin to pass through; and 
 an outer cover for closing the articulation device, provided with stops projecting outwards in the transverse direction (Y-Y) and designed to be inserted in suitable angular positions inside respective eyelets of the second ring, wherein the outer cover is provided with two diametrically opposite holes in turn aligned in the transverse direction with the holes of the intermediate body and the seats of the first ring and with an inner diameter such as to allow the insertion of a respective screw suitable for engagement with the female thread of the respective pin; 
   wherein, in use, the articulation device is in a position substantially aligned with malleoli of a user and includes them in the transverse direction within its thickness through the said first second rings and annular body.   
     
     
         2 . (canceled) 
     
     
         3 . Footwear according to  claim 1 , wherein one of the two seats is arranged between the two bottom-upper arms. 
     
     
         4 . (canceled) 
     
     
         5 . Footwear according to  claim 1 , wherein the annular body has two annular edges projecting in opposite senses along the transverse direction and with an outer diameter such as to allow the insertion, with slight friction inside the central opening, of the first ring and the second ring, respectively. 
     
     
         6 . Footwear according to  claim 1 , wherein the seats of the first ring, the holes of the intermediate body and the eyelets of the second ring are, in use, aligned with each other along the transverse axis. 
     
     
         7 . Footwear according to  claim 1 , wherein the thickness of the annular body is such as to allow the pins to project for insertion of their free ends inside the respective eyelet of the second ring. 
     
     
         8 . Footwear according to  claim 1 , wherein the thickness of the annular body and of the pins is such as to allow the latter to pass through the first ring and the intermediate body for insertion of their free end inside the respective eyelet of the second ring. 
     
     
         9 . Footwear according to  claim 1 , wherein the stops projecting from the cover in the transverse direction (Y-Y) are arranged in angular positions such as to be arranged between the pin and the terminal end of the eyelet of the second ring so as to form a different end-of-travel stop for relative rotation of the first ring and second ring. 
     
     
         10 . Footwear according to  claim 1 , wherein the front arm is fixed to the bottom upper in a position approximately corresponding to a metatarsal joint of a little toe and big toe of the user. 
     
     
         11 . Footwear according to  claim 1 , further comprising movable means for precisely adapting the closure of the upper to the volume of the calf muscle of the user. 
     
     
         12 . Footwear according to  claim 11 , wherein said means for adapting the closure comprises substantially two flaps designed to grip a calf muscle of the user and/or in that each flap is fastened to the respective arm of the articulation device, which is associated with the upper. 
     
     
         13 . Footwear according to  claim 12 , wherein each flap has on its rear face a rack section which is designed to mesh with a corresponding rack present on a front surface of a tongue for connecting together the two flaps. 
     
     
         14 . Footwear according to  claim 1 , wherein a sole, preferably designed with an asymmetrical form having a greater height on an inner side and smaller height on an outer side, is applied to the insole. 
     
     
         15 . Footwear according to  claim 1 , wherein the insole has an inner side which is substantially straight. 
     
     
         16 . Footwear according to  claim 1 , wherein a sole which has a substantially straight inner side is applied to the insole. 
     
     
         17 . Footwear according to  claim 1 , further comprising a reinforcing toe-piece provided with concavity applied to the toe of the said footwear. 
     
     
         18 . Footwear according to  claim 1 , further comprising a further reinforcement applied to the bottom upper in the vicinity of the outer surface of the toe of the footwear.
