Abstract
A heating device incorporated in an article of clothing or a shoe, notably a ski boot, comprising a sealed enclosure (2) in contact with the area of the body to be heated, this enclosure containing a salt (5) which changes phase between solid and liquid and has a latent fusion heat close to the normal temperature of the area of the body, from 30.degree. to 40.degree. C., and in which the heating resistance (6) is in a heat exchange with the salt contained in the sealed enclosure (2) such that after heating of the salt, as it returns to its solid state, it progressively gives off heat for a long period of time, while maintaining a substantially constant comfortable temperature.
