. n i "1 .i l i l' filaim. invention :relates' to .a novel'sho'e construe? tion and more particularly relates, to a novel combination of 'shoeshank and upper adapted to be used in womens shoes invs rhicli the shank is so shaped and positioned withrelation to the upper that the wearers foot rests "not onlyon the rigid shank, but the sides of the'footalso rest upon'and are embraced by the lower portionof the shoe upper thereby obtaining a glove-like fit of the upper about the foot. i 1

In women's shoes foot comfort and s'hoe: fit,

is often subservient'tos'hoestyle; Becauseofthe high heels employed andthfe. designiof the shoes;

it is necessary that arigid .s'hoe shankbe employed for the supportofl the .arch'. This-rigid shank, although serving to support the footis'to a certain extentuncomfortable.

The keystone ,of the arch isj thecuboid bone.

The surrounding bones ofthe arch'andf metag. tarsal namely the astragalus',"v scapuoidgand icu neiform bones, iall'd'ependupon the supporting effect of the cuboid bone; In order to obtain proper support for thefoot, it is necessary that the cuboid bone be maintained infp'roper position and that the ladjacent bones befalso held in their proper and respective position relative to the cuboid. v v 7, v

I have found that by causing'the arch .ofthe foot to be supported in partand to beembraced by the shoe upper, I can obtain amore scientifically improved shoe anda more comfortable sup.- port forthe foot, especially the "arch thereof.- I have further found that bycausing the-upper be so positioned with relation to the shank, ]that the foot rests partially upon the upperand is closely gripped thereby, that a betterfitof the upper, about the foot is also obtained. The afore' said arrangement eliminates gapping buckling and looseness and furthermore eliminates the bulges in the shoe upper that ordinarily oceur c ef-48.5) .i V at" the side'sthan has hitherto benthe practice iiilth arltlg I 1 p I 'Itisa' further object of my inventlonto provide a shank, deeply cut infat the sides so. that the upper combinedtherewith is adapted to support the sidesof the foot resting onthe' shank.

' ofa fstand ard 'shoefhav ng,a shank of 'n or'mal width showing the arch of the foot' supported on the hard shank and not' on the soft upper'leather; asinlIEig'; 5. I f i Ref rring now more specifically to the drawing, 1 there isshown'ashoe lflon awear ersffoot' ll. Thefshoej IO comprises av sole and an 'upperfattached thereto, f The upper is, shown in'the'drawing as an openiback, and is provided with the use of ordinary upper whilethe wearer of the'shoe is in the act ofwalking. st

My invention primarily is accomplished by employing a shank that is of lesser width in the longarch area than the ordinary shank and by bringing the upper out and away from the shank in such a manner that thewearers foot rests in part on the shank and on the} sides rests on the upper, the upper being caused to be fitted about the foot so that it closely embraces the same. c

To obtain the foregoing effect-the upper at the uppermost edge thereof is closelystitched and relatively non-elastic, but at the lower region thereof in the area where it-is adjacent the shank, the upper is relatively elastic and has a certain amountof give. v

It is the object of my invention'to provide a novel combination of shank and upper.

It is a further object of my invention to provide a shoe having a shank that is cut in deeper with gairearwardly extending'lstrap 'whi'ch -iis' adaptedto' embrace the 'upper' portlon of the heel of thefoo't ll.

'As shown in the drawing; the shank patien 6 of the sole between the heel portion thereof and; the ball portion of the sole, is out narrow on I opposite sides of the medial'line of theisole producinga shank oflnarrowed width The shank I B is narrower than shanks for standard soles of similar size and the decrease the width of the shank is not only on one side of the ,medialline, of thes ole but on both sides thereof. Thus, the upper of the shoe shownin Fig. 1 of the drawing for the v purpose of illustration, as broken away at" l3, whereby to show that at the bottom area l4 thereon on one side of the shank of the sole,v the shoe upp r 'curves downwardly. and under. the foot 'H to support a porti'on of the un derside of the foot on one side of the shank. Likewise the bottom-portion of the upper on the other side of the narrow shank also curves downa close i glove fit of t he uppel" o'nthefoota wardly under the foot to support the underside of the foot on the opposite side of said shank.

The dotted line 15 in Fig. 1 indicates the line of the shank of the shoe, and it will be noted that the shank is inwardly spaced from the margin of the underside of the foot so that side portions of the underside of the foot ll rest on portions of the upper adjacent the shank and on opposite sides of said shank.

In Figure 5 which shows in part a section along the line 5-5 of Figure 2, it will be seen that the shank l6 of the shoe I is cut particularly deeply at the side areas I! and l8 and this deep cut efiect is an important feature of my invention in that it insures that the foot will rest upon the soft and yielding portion l4 and 20 of the upper when the shoe is worn. Diagrammatically here the upper is shown positioned between the shank 1'6 and the outsole '2l. Thus, the shank is of narrower width than standard shanks for the same size shoe, but has the same longitudinal medial line since the edges i! and I8 are closer to said medial line than in standard shoes.

Figure represe'nts the positioning of the various parts of the shoe of my invention when a foot is placed within the shoe. The foot ll shown in dotted line rests centrally upon the shank I6 and at the sides rests upon the portion [4 of the upper and the portion 20 of the upper. The area I4 is beneath the inside of the foot namely the portion of the foot adjacent the long arch and this long arch area of the foot rests on the area M of the upper.

Because the sides of the foot rest upon the soft and resilient upper instead of the non-resilient and non-yielding shank l6, greater foot comfort results, and particularly a closer glove-like fit is obtained since in the act of walking the pressure of the foot downwardly upon the upper at M and 20 causes, for example,-the back strap 25, shown in Figure 2, of the shoe to more closely hug the heel. This elimination of the normal bulging or buckling of the shoe upper in the act of walking is of great importance since this relative movement 'of the upper during walking is responsible for blisters and foot discomfort as well as inferior appearance. a

In Figure 4 which is a plan view of the shoe, it will be noted that the deeply cut shank and the adjacent upper affords a partially rigid and partially resilient support for the foot. Specifically I have found that if I form the shank so that it is'approximately of an inch less in width on both sides in contrast to the normal standard shank of commerce for similar size shoe, then I can obtain the desired results here set forth.

The shank is cut deeply not only where the arch area joins the heel as at 30 and 3|, but also at the fore part or adjacent the ball area of the foot at 32 and 33.

In Figure 6 it will be noted that in the ordinary shoe, the foot 40 rests entirely upon and is supported by the rigid unyielding shank 4| and the upper 42 and 43 serves only to hold the foot in at the sides.

In contrast to the yielding resilient support and the glove like fit shown in Figure 3, the foot here is loosely encompassed by the upper and upon mo ement can obviously cause buckling and wrinkling.

The heel area 50 (see Figure 2) is sufiicient in area to afiord full and complete support for the heel of the wearers foot. The principle of employing a resilient support of the upper applies only to the long arch area of the shoe of my invention and not to the heel area.

Further, if the arch is improperly supported and the foot health may suffer by the dislocation of the cuboid and adjacent scaphoid bones.

Accordingly, I provide a novel shoe construction in which the shank is so cut and joined to the upper that the foot rests centrally upon the shank and at the sides upon the upper and is improving foot health and improving shoe appearance. It is an established fact that for increased foot comfort and foot health it is desirable that the various bones of the longitudinal or long arch, namely the keystone cuboid bone and theadjacent scaphoid; cuneiform and astragalus bones have a restricted amount of play so that the muscles and tendons'which join the various bones will retainor regaintheir desirable muscle tone. A limited movement of these parts promotes better circulation and releases cramped nerves 'and blood vessels. However,iit is desirable that this relative movement be restricted so that there will be no strain 'on the part and noconsequent weakening. By providing the additional resilient support for this long or longitudinal arch area of the foot by means of this newly described locationing of'the upper, the proper and extremely desirable resilient gripping of the arch and the various bones is afiorded.

From the standpoint of appearance'and style, this proper gripping of the longitudinal arch area of the foot, obviates sagging and spreading often found and more particularly because of the glove-like fit andresilient embrace of the foot by the upper, the gapping and'buckling of the upper with respect to the foot is obviated.

' Although my invention is here described and illustrated with respect'to a shoe having a back strap because the problems of gapping and buckling are of particular importance in this type of shoe,'my invention is applicable to shoes of other types and is-so intended.

I claim; 7

A shoe comprising a shank, an upper attached thereto and extending from the sides thereofl'said upper being formed with an open back and provided with a s'trap 'adapted to engage the back of the wearers foot, said shank being substantially narrower than shanksof standard shoes of similar size, while having substantially the same medial line as shanks of standard shoesof similar size, and portions of the upper on opposite sides of said shank underlying the undersides of the wearers foot -on opposite sides of the shank, whereby to resiliently support said side portions of the foot, and also to pull the strap' against the back of the wearers .foot, when the foot in the shoe :is :raised up n its toe to prevent gap between the strap and the back of the foot.
