<p>Sole (1) for shoes, comprising a container (9) housing a compressed gas including an active ingredient and provided with: an output (12) for dispensing the gas and actuating means (10) connected to said output (12) adapted to close and open said output so as to allow gas delivery. The sole is characterised in that said actuating means comprises an electro-magnet (15a, 15b) adapted to produce a magnetic field from an electrical current and a moving element configured to assume different positions under the control of said magnetic field. The electro-magnet is mechanically coupled to said output (12) so as to correspondingly close and open the output.</p> |
