In the present embodiment, the Alloy Foil band 11 of tape insulation layer turns to the sole shape and is clipped between sole 13 and the insulation cotton layer 12, pad 15, insulation cotton layer 12, shield 14 joined with two exits of Alloy Foil band 11 in power supply input jack 16 passed, the left and right footwear plug 24,25 that carries box inserts respectively in the jack 16 of two footwear, the Alloy Foil band is connected with temperature control circuit, opens switch 22,23 and can make Alloy Foil band heating (referring to Fig. 3～Fig. 5).

The structure of temperature control circuit is: the power supply II connects supply voltage condition indication circuit I, temperature auto-control circuit III respectively; Be provided with difference amplifier T1, T2, charge and discharge capacitance C1, light emitting diode LDE in supply voltage condition indication circuit I, the minimum voltage on the diode LDE is the input voltage of difference amplifier T1, T2; In temperature auto-control circuit III, be provided with thermistor Rt, operational amplifier IC1, IC3, integrated timer IC circuit 2, bidirectional triode thyristor BCR, the pin 3 of amplifier IC1 and the pin 6 of amplifier IC3 connect thermistor Rt branch road, the pin 2 of amplifier IC1, the pin 5 of amplifier IC3 meets variable resistor R9 respectively, the R13 branch road, the pin 1 of amplifier IC1, the pin 7 of amplifier IC3 connects the pin 2 of timer circuit IC2 respectively, 4, the pin 3 of timer circuit IC2 connects the control utmost point of bidirectional triode thyristor BCR through resistance R 14, inserts Alloy Foil band 11 between the pin 8 of timer circuit IC2 and bidirectional triode thyristor BCR.When bringing into use, the temperature of Alloy Foil band heating sheet 11 is lower than the lower limit temperature of setting, it is big that thermistor Rt resistance becomes, 1 pin of operational amplifier IC1 is an electronegative potential, then 2 pin of integrated timer IC circuit 2 get a low level, make its 3 pin output high potential, then bidirectional triode thyristor BCR conducting, heating sheet 11 gets electrical heating.Temperature rises, thermistor Rt resistance diminishes, when temperature is raised to ceiling temperature, the 7 pin output electronegative potential of operational amplifier IC3, the 4 pin preset ends of timer circuit IC2 get a low triggering level, and then timer circuit IC2 resets, its 3 pin output electronegative potential, bidirectional triode thyristor BCR ends, and 11 outages of heating sheet stop heating.Temperature repeats aforementioned process again when descending, thereby reaches thermostatic control (referring to Fig. 8).
