Fig. 3 is a sectional view of a snow boot according to the present invention; and

Fig. 4 is a schematic view of a snow boot according to the present invention in use.

As shown in the drawing, a snow boot 10 according to the invention in the embodiment shown has an outer body or outer body 20 and an inner body or inner body 30. The snow boot 10 is designed similarly to the known snow boots in terms of its external shape. The inner body 30 has a main body 31 which is provided with an entrance 32 for the foot and an air chamber 33 which extends along the circumference of the main body 31. The entrance 32 for the foot is provided on its inner wall with a lining 34 made of fabric and is further provided with a through opening 35 which penetrates the outer body wall and is in communication with the air chamber 33. The through opening 35 is provided with an air valve 50 in order to regulate the introduction of air into the air chamber 33.

To wear the boot 10, the foot is inserted into the inner body 30 through the foot entry 32. Then, an appropriate amount of air is introduced into the air chamber 33 through the air valve 50 to expand the main body 31 so that the inner wall and the outer wall of the main body 31 and the inner surface of a shoe opening 21 of the outer body 20 and the skin of the foot are in intimate contact and the foot is comfortably enclosed by the lining 34. As a result, the foot is kept warm. In other words, the inner body 30 is inflated with air 40 so that the inner body 30 is in intimate contact with the outer body 20 without hindering the movement of the foot, which is comfortably enclosed by the lining 32 of the inner body 30.

The entrance 32 of the main body 31 for the foot is provided with a slot 36 for enlarging the entry opening 32, in order to facilitate the entry for the foot.

According to the invention, therefore, there is provided a snow boot having an inner body and an outer body surrounding the inner body. The inner body is provided with an air chamber extending along the inner body to accommodate a quantity of air so as to allow the inner body to expand such that the wearer's foot is comfortably enclosed by the lining of the inner body and the wearer's foot is in close contact with the lining of the foot entry opening of the inner body to prevent the entry of cold ambient air into the boot.

With regard to matters not explained in detail above,
For further details of the invention, reference is expressly made to the claims and the drawings.
