CoR'rmA AFTER/VF) United States Patent- VENTILATED CUSHIONED SHOES Joseph Corfina, New York, N. Y. Application November 19, 1954, Serial No. 469,897

2 Claims. c1. 36-3) This invention relates to footwear.

It is an object of the present invention to provide footwear which is aerated so as to permit perspiration to be more rapidly evaporated and to prevent the footwear from acquiring the characteristic unpleasant odor of conventional shoes.

It is another object of the present invention to provide footwear of the above type which also serves to cushion the foot in a more comfortable manner.

It is still another object of the present invention to provide footwear of the above type which, due to the novel construction described above, will impart additional height to the wearer.

Other objects of the present invention are to provide footwear bearing the above objects in mind which is of simple construction, inexpensive to manufacture, has a minimum number of parts, is easy to assemble and comfortable in wear.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a perspective view of a preferred embodiment of the invention.

Fig. 2 is a longitudinal vertical sectional view thereof and showing the upper in phantom.

Fig. 3 is a view similar to Fig, 1 but showing the upper in phantom for clarity.

Fig. 4 is a longitudinal vertical section of a modified form of the invention and showing the shoe upper in phantom.

Referring now more in detail to the drawings, and more particularly to Figs. 1 through 3, represents an upper of any suitable construction which is secured in suitable manner, for example by stitching 13, to an inner sole 11 provided with the spaced perforations 12 throughout its entire surface, substantially as illustrated.

An elongated flexible strip 14 of leather or other suitable material having the longitudinally spaced perforations 15 depends from and is suitably secured to the undersurface of the inner sole 11 and upper 10 around the peripheries thereof, for example by stitching 13 (Fig. 2).

A plurality of transverse bridges or supports 17 of.

leather or other suitable material are suitably secured to the undersurface of the inner sole 11, the supports 17 being provided with longitudinally extending perforations 18 therethrough.

An outer sole is provided and includes the layers 19 and 20 and heel 21.

The lower edge of the strip 14 is secured to the periphery of the layer 19 by means of the stitching 22, the layer 19 being likewise suitably secured to the undersurface of the supports 17. Thus, the layer 19 serves to secure the upper portion of the footwear including strip 2,751, 92 Patented June 26, 1956 "ice 14 to the outer layer 20 and heel 21. The supports 17 serve to space the inner and outer soles.

Thus, an air space is provided intermediate the inner sole 11 and the outer sole, air being permitted to circulate freely through this air space from the foot of the wearer through the perforations 12 provided in the inner sole 11 and outwardly through the perforations 15 provided in the strip 14. Thus, perspiration may evaporate and escape downwardly through the perforations 12 and outwardly from the air space through the perforations 15, to render the shoe free from the customary unpleasant odors of conventional shoes.

The perforations 18 provided in the transverse supports 1'7 allow complete circulation of air through every portion of the shoe sole, as will be obvious.

Furthermore, this construction will serve as a cushion for the inner sole 11 and, inasmuch as the inner sole 11 is spaced from the outer sole, the shoe will provide additional height to the wearer.

During manufacture, the actual position of the transverse supports 17 longitudinally and transversely (angularly) of the shoe may be arbitrarily determined to avoid bunions, callouses or the like.

The perforated band 14 may, of course, be applied outside, as an extension of the sole.

Referring now particularly to Fig. 4, there is shown a modified form of the present invention designed to provide greater resilience at the heel of the shoe. In this form, the heel 21 is provided with a central bore 23 therethrough. A lower plate 25 is suitably secured to the undersurface of heel 21 The plate 25 will abut a resilient pad 24 secured to the bottom of a transverse supporting member 29 suitably secured to the undersurface of the inner sole 11.

Thus, when the shoe is in use, the plate 25 may be flexed upwardly by means of the pad 24 to permit greater resilience and comfort at the heel.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent 1. A shoe comprising a shoe upper, an inner sole secured to the bottom of said shoe upper and adapted to support the foot thereon, said inner sole being perforated, an outer sole, spacer means for supporting said inner sole on said outer sole in freely spaced relationship thereto whereby to provide an internal air space, a perforated strip connecting and secured to the peripheries of said inner and outer soles, whereby to permit the circulation of air downwardly through said inner sole and outwardly through said perforated strip, said spacer means comprising a plurality of longitudinally spaced, transverse supporting members secured to the undersurface of said inner sole and supported on said outer sole, said transverse members being perforated longitudinally whereby to allow complete circulation of air through every portion of the shoe, said outer sole including an inner layer supporting the undersurface of said transverse members, the lower edges of said perforated strip being secured to the periphery of said inner layer, said outer sole including a heel, said heel having a central bore therethrough, a bottom plate secured to said heel, and resilient spacer means secured to the undersurface of said inner sole within said bore and adapted to abut the inner face of said plate, said resilient spacer means comprising a rigid supporting member secured to the undersurface of said inner sole and a resilient pad at the lower end of said supporting member.

2. A shoe comprising ashoe upper, an inner sole secured to the bottom of the shoe upper and having perforations therein; an outer sole including inner and outer layers spaced from'the inner sole, spaced blocks ofleather interposed in the space between the'soles for spacing same from each other, said blocks having openingstherethrough disposed in the direction of the length of the shoe, a strip closing the space 'betweenthe inner and outer soles and being secured'to theouter peripheral edges of saidsoles, said strip having perforations communicating with the atmosphere andwith the space between the soles, stitching securing the edges of the strip to the edges of the soles, and a hollow heel secured to the outer sole including anouter plate, a block secured to the surface of the inner sole centrally of the heel and spacing saidouter plate from the inner sole, said block having an opening therethrough aligned with the openings in adjacent leather blocks, and a rubber pad interposed between the block and plate.
