Abstact A method of treating shoe parts having a coating of a moisture-curable composition utilizes an apparatus in which a support (16) for an article, e.g. a lasted shoe S, can be supported within a chamber (30) in which the support can be enclosed. The chamber (30) is supplied with heat and moisture. More especially, the article is subjected to infra-red radiation from a heater (44) and steam is supplied to the chamber (30) such that the humidity of the atmosphere within the chamber (30) is maintained during the operating cycle at a dew point of between 50 and 60°C. The surface temperature of the heater (44) is between 250 and 420°C, preferably between 300 and 380°C, and the article is subjected to infra-red radiation for a period of between 5 and 25 seconds, preferably 10 seconds. Because the chamber (30) is enclosed, steam is supplied for only the first 5 seconds of the heating period. To facilitate work handling, the support (16) is movable between a loading/unloading position and an operative position within the chamber (30), and an arrangement of screens (52, 54) is provided for closing the chamber respectively in the loading/unloading position and the operative position. The screens also serve to cause the steam created during a cycle of operation to be evacuated into ambient atmosphere at the end of each operating cycle.
