Sports and/or orthopaedic footwear with device for relative articulation between insole and upper

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.
