Sports shoe having a shell ( ) partially overlapped by a leg-piece ( ) and adjusting hinge ( ) for allowing a flexing movement of controlled amplitude of the leg-piece about a hinging axis. In the overlapping zones (ZE, ZI) plates ( ) provided on the outer surfaces of the leg-piece ( ) allow selective insertion and subsequent locking of at least one hinge ( ) in any one of the matching seats ( ) provided on the shell ( ). The hinging axis thus able to assume at least two different angular positions (X , X , X , X ) relative to the longitudinal centre plane (M) of the shoe, as required by the user.

Sports shoe with leg-piece hinged on the shell

The upper part ( ) of the shell ( ), manufactured as one piece from polymer material, of a footwear is divided on the front into two pairs of flaps ( A, A; B, B) by a longitudinal separating line ( ) and by a transverse slit provided opposite the user's heel. Two removable inserts ( ) are provided, which may even be manufactured using a type of polymer material different from that of the shell ( ), have parts ( ) which are designed to interfere both with the outer surface and with the inner surface of the said flaps ( A, A; B, B) and also have interconnecting parts ( ) which are designed to be retained by the twfo sections ( A, B) of the transverse slit. USE: Ski boots and skating boots, safety footwear and the like. ADVANTAGES: No infiltration (e.g. of water and snow) into the boot; more efficient manufacturing of the boot.
