Abstract
An item of wearing apparel, such as a ski shoe or boot, provided with an energy source and an energy consuming device, such as a heater, and a mechanism for automatically terminating the energy supply as soon as the wearer removes the item of apparel. More specifically, the ski shoe or boot includes a shell base on which is journalled at least one movable upper element, such as a rear spoiler or a front cuff, to permit insertion and removal of the boot, wherein the boot includes a device controlling the energy supply of the consuming device. The boot further includes a linkage device between the movable upper element and the device controlling the energy supply so as to allow the energy supply of the consuming device only when the movable element of the boot is closed and to automatically cause the fuel supply to be shut off as soon as the movable element of the boot is moved toward the open position.
