Thermal shoe

The invention relates to a thermal shoe. The thermal shoe comprises a sole, a vamp, a shoe tube, a heating device, a circulation groove, a waterproof layer, an exhaust groove, a blocking sheet, a protective soft board, a groove, a micro cylinder, a water storage tank, a gas permeable membrane, a water injection tank, a bucket and a first magnetic block, wherein when the bucket closes an opening ofthe water injection tank, the bucket and the sole are squeezed; after the heating device is started, water in a water outlet groove is heated to be evaporated to form water vapor passing through thegas permeable membrane and entering the circulation groove, since the specific heat capacity of the water is larger, a warm state can be maintained for a long time, and since the water vapor increases, the gas pressure can increase to jack up the blocking sheet, therefore the water vapor escapes from the shoe tube; the water in the water outlet groove needs to be supplemented regularly, the bucketis rotated, thereby putting the water into space formed by the bucket, then the bucket is rotated to transfer the water into the water injection tank; the first magnetic block can enhance the connection strength between the bucket and the sole and enhance the sealing property.
