To all whom t may concern.'

Be it known that I, LEONE LAzzARr, a citizen of the United States, and a resident of Greenville, county of Hudson, and State of New Jersey, have invented certain new and useful improvements in Ventilated Waterproof Shoes.

My invention relates to means forventilating and cushioning waterproof shoes to provide maximum comfort to the wearer,

and at the same time to avoid the usual ventilating apertures through the walls of the shoe which are objectionable for anumber of reasons, particularly in pei'inittinJ the passage of moisture into the shoe.

objects of the invention will hereinafter apear. p The invention will be understood by reference to they accompanying drawings, in 2a which- Fig. l is a perspective view of a shoe embodying' the improvements,- with the upper cut away.

Fig. 2A is a cross section on lines 2--2, at Fi l.

ig. 3 is a plan view of the Ventilating cushion sole.

My shoe consists of the upper l, which is secured toa welt 2 in the usual manner, and the outsole 3 is attached to the welt as customary. Disposed immediately above the out- Sole is the Ventilating cushion sole A, which may be otrubber or other flexible spring/y material, rubber being preferred. The ventilating sole preferably is formed with the marginal ange a which is co-extensive with the outer sole 3 and thus is disposed intermediate the latter and the welt 2, being stitched thereto. Howeven the construction and arrangement of the Ventilating sole and its relation to the inner sole is such that it is securely held in position independently of the Hange and stitching, so that the flan e may be omitted if desired. Generally, t e t5 flange is desirable because itvaids in waterproofing the shoe. Disposed above the ventilatingl sole A is the insole 4.

From the plan View of the Ventilating sole HA in Fig. 3, it will be seen that it is formed at certain points, with the upwardly p rojecting lugs or teats b, each teat belng formed with a central vertical aperture b Referring to Fig. 2, it will be noted that the apertures b do not pass through the ventither latingv sole, but the aperture in each case merges into a lateral aperture b which passes through the wall of the teat and into register with a groove or channel c extending4 longitudinally of the Ventilating sole. The said Ventilating sole is formed with a plurality of the longitudinal channels 0the v channels merging at each end of the sole lintoa connecting channel d, so that air may pass from one longitudinal channel to another, via a connecting channel d (F ig. 3). 65

ln the present embodiment of the invention, l have provided a series of two of the apertured vlugs or teats b in` such position as to be immediately below the toe arch, or first phalangeal joint, of the foot and a sin- 7o gle apertured teat b in such position as to be immediately under the central or main arch of the foot. The teats pass upwardly through suitable apertures formed in the insole and preferably lie flush with the upper surface of the latter, although if thev channels c are deep and there is very substantial yield of the Ventilating Sole and hence depression of the insole the teatsv may be so proportioned that their upper sur- 8o -faces will normally be somewhatA below the upper surface' of the insole.

In the use of the shoe and when the foot descends, the pressure ofthe foot upon the insole will depress and partly collapse the Ventilating sole 'andair will be forced from the channel c and d, through the apertures b and b in the teats and thence into the shoe above the insole. When the foot is lifted and the pressure released the ventilating sole will, through its elasticity, be restored to its normal position, and air will thereby be drawn into the top oi the shoe about the foot of the wearell and will pass into`the channels. ln' this manner a circu- @5 lation of air through the shoe is eected and ventilation of the shoe is thus maintained.

As the outer sole of a shoe wears away in use and its thickness decreases, the innersole moves downward accordingly and lbe- 10@ comes displaced to such an extent that cracks are formed in the ordinary libre sole when the outersole'is Worn through or thereabouts. For this reason and because of the yielding nature of intermediate. cushion ventilatin soles, it is practically impossible to proper ventilata a shoe through perforatons 1n the -insole placed in register with transverse or longitudinal channels in the cushion Ventilating sole. ln the movement of the soles the Iperforations in the insole will inmany cases be carried out of register with the channels vand be closed by a Jwall of the cushion Ventilating sole. rlhis diliculty entirely overcome by the formation of my Ventilating sole and its cooperation with the insole. The passage of air from the,ventilating\so1e to above the insole and vice versa is via apertures in members which project upwardly through the insole and which lock the ventilatin and insoles together against relative ateral movement. These members are so posi- -tioned, beneath arches of the foot, that even should they be slightly projected above the insole, in the act of walking, they will not come into contact with the foot. 4

It will be understood that any desired number of lugs or teats. may be carried by the Ventilating sole, and that various modiylications may be made in the embodimentof the invention shown in the drawings,

intense without departing from the spirit/of my invention.

What ll claim is: y
