A shoe (1) having an active air-conditioning device (2) for maintaining the temperature inside the shoe (1) at a value selectively above or below the temperature of the outside environment. The air-conditioning device(20) is integrated in the sole (3) of the shoe (1), and comprises a main heat exchanger (4) for exchanging heat with the inside of the shoe (1), and air compressing device (5) for feeding a pressurized air stream to the main heat exchanger (4), an auxiliary heat exchanger (10) located between the air compressing device (5) and the main heat exchanger (4) to reduce the temperature of the pressurized air stream, an expansion valve (11) located immediately downstream from the auxiliary heat exchanger (10) to rapidly expand and so cool the pressurized air stream, and a bypass conduit (12) with a relative on-off valve (13), for connecting the main heat exchanger (4) directly to the air compressing device.
