10 Claims.

The invention relates to shoes, as described in the present specification and illustrated in the accompanying drawings that form part of the same. i

The invention consists essentially in the circulation and diffusion of gases within the shoe and the flexibility of the foot supporting parts contributing to the aforesaid circulation and to the lifting of the arch with comfort to the wearer,

as pointed out in the claims for novelty following an explanation of the structural details and the operation.

The objects of the invention are to maintain the feet of the wearer in a sweet and wholesome 1&- condition and thereby eliminate offensive odors and rankness due to excess exudations from the skin and any ioulness appearing on the surface and resulting from internal troubles and in fact to medicate the shoe thoroughly by the natural muscular movements of the feet in pumping air and remedial gases constantly about the feet; to insure a handsome and trim appearance that is so necessary to a well dressed person and yet include all the required provisions for the pecu- 35 liarities of the person's feet; to furnish shoes to the people at large that materially aid in guard- .ing against the development of bad feet conditions, and generally to bring about conditions of comfort to the public, especially in regard to the :10 state of their feet.

In the drawings, Figure l is a plan view looking in the shoe showing the ventilated insole and arch extensions and the cushion pads for medicaments.

Figure 2 is a longitudinal sectional view on the line 22 in Figure 1. 7

Figure 3 is a plan view of the inside layers of the build-up of the shoe below the insole on the welt foundation and minus the outsole.

Figure 4 is a plan view showing a detail of the insole.

Figure 5 is a detail of the aluminum plate.

Figure 6 is a perspective view of the equalizer or lift insert.

Figure '7 is a detail of the channelled metal shank.

Figure 8 is a cross sectional view on the line lt-B in-Flgure 1.

Figure 9 is a plan view of the modified form of the arch support. I

Figure 10 is a detail of an anatomical last, shown in cross section.

Like numerals of reference indicate corresponding parts in the various figures.

- Referring to the drawings, the shoe is made up of the outsole it, the upper l8, including the vamp and toe cap portion l1, and the insole ll attached to said upper, the shoe that is the only difference in the outsole the insole and the interior side thereof to support lift l9, which raises of the shoe on the inner greatest concern,

but it is the interior of and the part of it is the the arch of the foot. This is done by an anatomical last and adding a wedge hereinbefore termed the lift, frequently mentioned as the 10 equalizer, which is an insert disappears transversely to a insert of leather of leather, and this thin edge and also disappears to a thin edge at each end, being at its thickest towards the front end and gradually shelving off towards the other 15 end and to the edge.

It will thus be seen that the raised side of the shoe, that is to say, the the foot of the wearer, action in distributing inside, straightens out so that the pumping substances is natural and efflcient whereas otherwise it would not to a natural position, the

be so effective, but by raising the foot to be moved muscular activities of the wearer in moving about and walking result in all the actions that produce a suction power for drawing the vapors from a number of cubes 2| and pads 22 containing iodine, alcohol, menthol, castor-oil, mint and thyme which is a comthe vapor of medicated 2o pound of a non-acid and vegetable nature, for

distribution of vapors, them throughout the shoe the foot.

and in fact circulating and around and about The shoe i5 is constructed to give the maximum of support to the to carry out the objects aforesaid, the anatomical last 20 is cut away side at the arch from transversely on the inner the normal lines shown in the dotted lines to the solid line.

The inner sole I. is skived at the edge in the the leather surface 23 on the usual manner with inner side which is extended the form of the splits 25, these lugs being and shape to conform to of the last 20.

The inner sole is into the lugs 24 in of a size the cut away portion blocked or moulded to the last, which naturally raises the center of the inner sole from the flat at top of the lugs 24.

a maximum of the the outer edge 18 to The edges key bones of the feet and of the lugs are skived on the flesh side to a thin e. An aluminum supporting plate 21 of the same size as the extension piece 24 is cut to form

sections

28, 29 and mentary to lugs 24 and is of the inner sole 3B complemoulded to the shape of the last and the extension piece, a flange 3i substantially horizontal secures the plate 21 to the under surface of the inner sole by the rivets or nails II.

The lugs 24 of the inner sole may be secured to sections 2!, 28 and ill of the plate 21.

Within the area of the skived edge of the under side of the inner sole l8 bounded by the skived edge SI, a cushion pad 8. is placed and extends the full length of the inner sole, this pad or cushion 34 is formed of a layer of felt it and outer coverings 38 of silk.

A sheet of asbestos 31 is then placed over the pad or cushion 34 on the under side and the cushion and asbestos sheet may be held to the under surface of the inner sole in any suitable manner, such as by the nails or tacks 38 or they may be cemented or pasted in place. The thickness of the cushion 3i and asbestos sheet 31 combined are equal to the depth of the skived edge II of the inner sole I8.

After the upper l8 and the welt lll are secured to the lip ll of the inner sole in the usual manher and the welt pressed out, a leather equalizer I8 is then secured to the under side of the inner sole i8 and cushion pad 34.

The leather equalizer l9 extends into the heel portion 43, the narrowed center is the arch portion 44 and the forward spread portion 45 is in line with the ball of the foot.

The equalizer I9 is wedge shape in transverse section and the depth on the inner and outer edges is equal to that cut away from the last 20.

The thickness along the lifting edge 46 of the equalizer increases slightly from the spread portion 45 to the rear of the arch portion 44, where it is tapered to about half the thickness along the edge 41 to the forward edge 48 where it is tapered off to a knife edge in line with the ball of the foot.

The depth and shape of the equalizer I9 is equivalent to the amount of material taken off the last 26 and is intended in the shoe construction to correspond with the material.

The equalizer is secured to the outer surface of the cushion 34 and inner sole It by the nails 49. Against the outer surface of the equalizer IS an aluminum base plate 50 is secured and this base plate is smaller in size but follows generally the shape of the leather equalizer I9 and is secured to the equalizer centrally with the longitudinal axis A3. of the shoe and forms a base on which is mounted the steel truss 5| moulded to conform to the last 20 on the axis AB. and

' has a fiat heel portion 52 extending into aisubstantially trough shaped arch portion 53 and terminates in a fiat spread portion 54 under the ball of the foot.

The outer sole 55 is now attached to the welt ID in the usual manner closing and providing a solid base for the arch support.

In Figure 9 a modified form of support is shown. In place of the leather of the inner sole ll being extended, an extra inner sole 55 is provided with an aluminum support 50 setbetween the sole l8 and sole 55.

The aluminum support it conforms in the flat portion 51 to the shape and mould of the inner sole 55, while the extension portion is moulded to the arch portion of the last 20 and is slotted inwardly from its upper edge into sections 58 in the same manner as the leather lugs 24 of the inner sole IS.

A covering 59 is provided to the support 56 to protect the foot and shoe from the edges of the projecting sections.

With this construction, a shoe is produced which is designed from the very first operation to give the maximum of support and comfort, and for this reason the last is prepared and cut away so that the shoe built on the last will conform to and support the os calcis, the scaphoid, the astragalus, the cuneiform and the metatarsal bones forward to the ball of the foot, and by moulding the inner sole with its arch extension cut in sections, the cushion pad, the equalizer and the aluminum and steel trusses to this last, the whole shoe holds and supports these bones of the feet in their proper relationship and so long as these bones retain their position there can be no deformation of the feet.

The same applies to the shoe itself for when it is built on a last, which is anatomically true to the arch of the foot, the foot and the shoe work together, and no deformation of either of them can take place.

The cubes 2| contain the desired ingredients and are supplied with silk wrappers 58 to constitute an absorbent and the latter are pushed through the apertures 59 in the insole, still containing the compound, the eflluvia of which materially helps the foot to comfort and health. The pads 22 also are contained in quilted silk. forming inserts at various places in the lining. The sanitary eii'ect of the sole absorbent is also very active in spreading the medicine for the ease of the fight against such foreign influences as may enter the shoe.

The inner sole being first moulded to the anatomical last and having the arch extension with its aluminum supporting plates insures the absolute comfort of support, as the lugs of the extension give a degree of elasticity beneficial to the muscles which hold and operate the key bones of the arch and thoroughly medicate the foot.

In placing the steel truss with its aluminum base between the outer sole and the equalizer, the strain between the heel and the ball of the foot is amply provided for while the thrust is 'distributed throughout the equalizer, and the cushion acts as a. shock absorber to the inner sole.

The equalizer further takes up the amount taken from the anatomical last so that the outer sole will be a natural tread and a base between the heel and the ball of the foot for the built up arch allowing the metal truss to have a level balance giving a true upright support while transferring the support to the moulded upper surface of the inner sole and the arch of the foot. The placing of the equalizer between the inner sole and the arch supporting truss allows for distribution of the support without the truss working into and through the inner sole and at the same time allows for the outer sole to retain a normal tread line and generally keeps the uppers and soles free from distortion while holding the bones of the feet in place and preventing deformation and insuring the muscular movements required to circulate the curative vapors.
