Abstract:
A shoe sole having ventilating openings between the atmosphere and the interior of the shoe. The air flows through sealable openings in the heel and enters the interior of the shoe through further openings in the foot engaging portions of the sole. The openings in the heel are sealable by keys which close the openings upon application of pressure by the heel of the user when walking.

Description:
BACKGROUND OF THE INVENTION 
     (1) Field of the Invention 
     This invention relates to which keeps the inner side of shoes dry by ventilating the air in shoes, providing the walker with a comfortable feeling as well as removing the bad smell emitted from the inside of shoes by establishing a hollow zone between the outersole and the innersole 
     (2) Description of the Prior Art 
     In traditional shoes, there has been one or two ventilating openings on the side of shoes, numorous ventilating holes on the top of shoes for ventilating the air in the shoes. In addition, for the same purpose, the vamps or the uppers of shoes are made of gauze for use in the summer season. 
     Nevertheless, because the sole of the foot is stuck to the innersole or the outersole while in shoes, such ventilation is only local in nature. As a result, the above techniques could not prevent odors or athlete&#39;s foot. 
     SUMMARY OF THE INVENTION 
     The shoe sole of the present invention includes a first embodiment having four main parts (i.e., the heel, the outersole, the hucklebone, the innersole and the half top), and a second embodiment having five main parts, (i.e. the incorporation of the heel and the outersole, the hucklebone, the innersole and the half top). In the first embodiment, a U-shaped air exit is established on the heel alongside the edge thereof. In the second embodiment, a number of side air exits are formed on the outer edge of the heel. In both embodiments, a hucklebone room and a hollow zone are established on the outersole. In addition, the shoe soles include a number of narrow ventilating holes which penetrate the innersole, two water-proof keys, a hucklebone lid, numorous downward projections beneath the innersole, and numorous round ventilating holes which penetrate on the innersole. Furthermore, the soles include numorous round ventilating holes which penetrate on the half top and several supporting bridges beneath the half top. 
     It is a feature of the shoe sole of the present invention to remove the aforesaid traditional defaults by keeping the inside of the shoes dry and well ventilated by establishing air exit(s) in the heel. 
     It is a further feature of the invention to provide a shoe sole which cushions the feet during use and creates a feeling of dryness by use of numorous projections beneath the innersole which are highly effective in ventilating odors of the foot as well as in preventing athlete&#39;s foot.

     DETAILED DESCRIPTION OF THE INVENTION 
     As illustrated in the FIG. 1, along the outer edge of the outersole (1) there is an upwardly projecting fence (2). On the outersole adjacent a heel (8) there is a hucklebone room (3) on the hucklebone supporting plate (4), a number of narrow ventilating holes (5) and two water-proof keys (7)(7&#39;) at both ends of the arrangement of the narrow ventilating holes between the supporting plate (4) and the fence (2). On the heel (8), a U-shaped air exit channel (9) is established, will be positioned below the narrow ventilating holes (5) and the water-proof keys (7, 7&#39;, each having portions projecting from the upper and lower surface of said outer sole as shown in FIGS. 3a and 3b) when the outersole (1) and heel (8) are joined together. 
     Further, beneath the outer edge of the innersole (10), there is a fence (11) established to abut the fence (2) of the outer sole (1). On the innersole (10) adjacent the heel (8) there is a hucklebone lid (13) which extends to the middle of the innersole (10) and a number of narrow ventilating holes (5&#39;) between the hucklebone lid (13) and fence (2). Beneath the front side of the innersole (10), a number of round ventilating holes (15) and projections (14) (having openings therethrough (FIG. 4)) equal in height to the fence (11) are alternately established. In addition, there is a fence (17) projecting downwardly along the outer edge of the tap (16), numorous round ventilating holes (15&#39;) and several supporting bridges (18) equal in height to the fence (17) along the center line of the half top (16). Accordingly, the heel (8), the outersole (1), the hucklebone (12), the innersole (10) and finally the tap (16) are coupled to one another in the manner shown in FIG. 2 to form the shoe sole of the present invention. 
     An alternative embodiment is illustrated in FIG. 5, wherein the heel (8) and the outersole (1) are to be manufactured as one body. In this instance a number of extrusions (2&#34;) are established along the rear fence (2&#39;) of the combined shoe sole (19) to form the side air exits (20). Also the hucklebone (12) and the supporting plate thereof (4&#39;) are formed as explained above in connection with FIG. 1. Additionally, between the extrusion (2&#34;) and the supporting plate (4&#39;) is a hollow zone (20&#39;) and a hucklebone room (3&#39;) in the middle of the supporting plate (4&#39;) established is the hucklebone room (3&#39;). 
     In light of the structure of the present invention, when the innersole (10) and the outersole (1) are adhered to each other by an adhesive agent, the hucklebone lid (13) and the hucklebone supporting plate (4) (4&#39;) engage the hucklebone (12), while the fence (11) of the innersole (10) and the counterpart fence (2) (2&#39;) (2&#34;) of the outersole (1) are in alignment with one another respectively. Accordingly, the air exit (9) or the side air exits (20) on the heel (8) (8&#39;) will communicate with the narrow and round ventilating holes (5) (5&#39;) (15) through the hollow zone (12). 
     In the combined shoe sole of FIG. 5, the air may enter into or be emitted through the side air exits (20) via the narrow ventilating holes (5), the hollow zone (6), the hollow alley (20&#39;), the hollow zone (21) of the front side and the narrow ventilating holes (15&#39;). Since the innersole (10) has numorous projections (14), it will cause emittion and absorption of the air as well as cushion the feet while walking. As illustrated in FIG. 3, the water-proof keys (7, 7&#39;) will keep away the water on rainy days becasue the water-proof keys (7) (7&#39;) are pressed by the weight of the wearer to close the air exit (9) so as to keep the shoes clean and dry.
