of the heel touches the ground. During further walkingmovement the heel turns about this edge until the entire heel bottom 5 is in contact with the ground.

During such turning movement of the heel, water locatedin the path of the bottom face 5 of the heel will be sucked up by the spongy mate rial 8 in the holes 6, 6 and conveyed by the same through these holes into the cavty 2 where t is retained within the spongy material 8 arranged within the cavty 2.

When, during further walking movement, the entre bottom face5 of the heel touchng the ground is compressed by the weight of the walking persen, the cavty 2 within the heel is compressed too, whereby the water absorbed by the spongymaterial 8 within this cavty will be ejected tlirough the slot 7 into the space under the shank of the shoe. tion of water cannot case any splashing whch mightreach the upper part of the shoe or-the garments of the walking person.

During further walking movement, the shoe is turned around the front portion of the sole and thereby the heel is lifted from the ground. This causes: the water around the heel to flow under the same nto contact with the bottom face 5 of the heel. This water is then absorbed by the spongy material 8 which due to its compression was freed from water contained therein. Thus,

the water fiowing under the heel during lifting of the same is completely absorbed and cannot cause splashing.

It will be understood that each of the elements described above, or two ormore together, may

also find a useful application in other types of rubber heels dffering from the types described above;

Whle I have illustrated and described the invention as mbodied in rubber heels, I do not" intend to be limted to the details shown. since. various modifications and structural changes may be made without departingin any way from the spirit of my invention.

Without further analyss, the foregoing will so fully reveal the gist of my inventon that others can by applying cu1rent knowledge readily adapt it for varous applcations without omitting features that, from the standpoint of prior art, farly constitute essential characteristcs of the generic or. specific aspects of this invention, and, therefore, such adaptatons should and are intended to be comprehended within the meaning and range of equivalence of the following claims. What I claimas new and desire to secure by Letters Patent is:

A rubber heel comprsing in combnaton a rubber heel body havng a bottom face and a front face; at least one duet extending in said heel body substantially parallel to said bottom face and opening in said front face; at least on hole connecting said duet within said heel body 4 with said bottom face of said heel body; and a water absorbent sponge member arranged within said duet and said hole or holes and completely filling the same.

2. A rubber heel comprising in combination a rubber heel body having a fiat bottom face and a front face; a flat cavty arranged within said rubber heel body parallel to said flat bottom face and being slightly smaller than said bottom face; and extending to said front face; at least one hole connecting said fiat cavty with said bottom face of said heel body; and a water absorbent sponge member arranged within said flat cavty and ex tending to said front face and said bottom face of said heel body.

3. A rubber heel comprising in combnation a rubber heel body having a flat bottom face, a

It is evident that such ejecfront face and a rear face; a flat cavty arranged within said rubber heel body parallel to said fiat bottom face and extending from said front face almost to said rear face; a hole arranged near said rear face of said rubber heel body and corrnecting said cavty within said rubber heel body with said bottom face thereof; and a water absorbent sponge member arranged within said flat cavty and said hole and extending to said front face and said bottom face of said rubber heel body.

4. A rubber heel comprising in combihation a rubber heel body having a flat botton facea front face and a rear face; a-flat cavty arranged within said rubber heel body parallel to said flat bottom face and extending from said front face almost to said rear face; a hole arranged near said rear face of said rubber heel body and connecting said cavty within said rubber heelbody with said bottom face thereof; at least one addtional hole arranged in said bottom face of -said rubber heel body at substantially equal distance from. said rear face and said front face thereof and connecting said fiat cavty within said rubber heel body with said bottom face thereof; and a water-absorbent sponge member arranged within said fiat cavty and said holes and extending te said front face and said bottom faceof said rubber heel body.
