ABSTRACT:
A ski-boot heater has a heating resistor and a battery mounted in the boot and a socket is provided in the boot for connecting the resistor and the battery to an external voltage source. A control circuit enables the battery to be recharged with direct current when the socket is connected to an external AC or DC supply and when the battery is being recharged enables the resistor to be supplied with electrical power greater than that normally supplied to the resistor by the battery.
