Optionally, in order to prevent the melted snow water from entering the interior of the climbing boot, the snow melting strip 42 includes a heat conduction section 421 and a snow melting section 422, the snow melting section 422 is connected to the heat transfer sheet 4 through the heat conduction section 421, and the cross-sectional area of the snow melting section 422 is larger than that of the heat conduction section 421. Accordingly, the shape of the snow-melting notch 24 is adapted to the shape of the snow-melting strip 42, and the bottom surface of the snow-melting section 422 is flush with the bottom surface of the anti-slip groove 23. Because the cross-sectional area of the snow melting section 422 is larger than that of the heat conduction section 421, and the shape of the snow melting notch 24 is adapted to the shape of the snow melting strip 42, when snow water appears in the anti-skid groove 23, the snow water can be blocked by the cooperation of the snow melting section 422 and the snow melting notch 24, so that the snow water is prevented from extending into the sole 2 along the snow melting notch 24.

In addition, for further promoting this climbing boot's waterproof ability, the shoe inner layer includes waterproof layer 6, waterproof layer 6 sets up between heat transfer sheet 4 and zone of heating 3, is equipped with passageway hole 61 on waterproof layer 6, inside passageway hole 61 was arranged in to heat conduction post 41. In order to prevent snow water from flowing toward the heating layer 3 along the passage hole 61, the heat conduction column 41 includes a first connection section 411 and a second connection section 412. Specifically, the first connection section 411 is disposed on the top surface of the heat transfer sheet 4, the second connection section 412 is disposed on the top of the first connection section 411, and the diameter of the second connection section 412 is smaller than that of the first connection section 411. Accordingly, the passage opening 61 comprises a first receiving section adapted to the first connecting section 411 and a second receiving section adapted to the second connecting section 412. After the installation is completed, the shaft shoulder position of the first connecting section 411 will be attached to the diameter-changing positions of the first accommodating section and the second accommodating section, the waterproof performance inside the channel hole 61 can be improved through the structure, and snow water is prevented from flowing along the channel hole 61.

In the actual life process, because the inside on snow road surface can often form the ice surface because of ice and snow melts and temperature dip, when the user walks on the ice surface, traditional skid resistant pattern can not provide sufficient land fertility, therefore the user still can have the risk of skidding. In this embodiment, for promoting the anti-skidding ability of climbing boot on the ice surface, 2 insides of sole are equipped with the antiskid nail, can destroy the smooth degree of ice surface through the antiskid nail to promote the coefficient of friction between sole 2 and the ice surface.

Specifically, an accommodating cavity 221 is formed in the anti-slip protrusion 22, a communication hole 222 is formed in the bottom surface of the accommodating cavity 221, and the accommodating cavity 221 is communicated with the outside through the communication hole 222. The bottom surface of the heat transfer sheet 4 is provided with a connecting column 43, the connecting column 43 is arranged in the accommodating cavity 221, the connecting column 43 is provided with a non-slip nail, the bottom of the non-slip nail is provided with a conical nail head 54, and the conical nail head 54 extends to the outside of the sole 2 along the communicating hole 222.

Because the tapered nail head 54 is positioned below the sole 2, when a user stands on the ice surface with the climbing shoe, the tapered nail head 54 can be inserted into the ice surface, and the grip of the climbing shoe on the ice surface can be improved through the process, so that the phenomenon of skidding of the user is avoided. In addition, since the heat transfer sheet 4 can conduct heat, when the heating sheet 311 starts to generate heat, the heat transfer sheet 4 can transfer heat to the stud through the connecting column 43, and the heat can melt the ice surface in contact with the tapered stud 54, thereby reducing the difficulty of inserting the stud into the ice surface.

Fig. 8 is a schematic structural view of the stud of this embodiment, as shown, in order to prolong the useful life of the stud, the stud comprises: the heat transfer plate comprises a connecting pipe 51, a spring 52 and a retainer ring 53, wherein the connecting pipe 51 is sleeved on the connecting column 43, the retainer ring 53 is arranged on the outer wall of the connecting pipe 51, the spring 52 is sleeved on the connecting pipe 51, one end of the spring 52 is connected with the top surface of the retainer ring 53, and the other end of the spring 52 is connected with the bottom surface of the heat transfer plate 4.

When a user walks on a hard ground (such as a cement ground), the spring 52 is compressed due to the weight of the human body because the anti-skid stud cannot be inserted into the ground, and the tapered stud 54 retracts into the communication hole 222; when a user walks on the ice, the heated anti-skid studs can be inserted into the ice, so that the springs 52 are not compressed, and the tapered studs 54 extend out of the bottom surface of the sole 2, thereby improving the anti-skid capability of the climbing shoe.

As an alternative to this embodiment, in order to improve the comfort of the user's foot in the present climbing shoe, the insole further comprises a heat conductive layer 7, said heat conductive layer 7 being arranged above the heating layer 3.
