My invention relates broadly to shoes and more particularly to an improve-d construction of saddle insole for shoes.

One of the objects of my invention is to provide a construction of saddle insole for shoes which will provide a substantial support for the .calcaneus, astragalus, sCaphOid, internal cuneiform, and great toe metatarsal bones of the foot.

Another object of my invention is to provide a construction of saddle insole having a resilient reinforcement adapted to lmaintain the shape of the saddle insole over a relatively long period of wear of the shoe in which the saddle insole is employed.

Still another object of my invention is to pro- I vide a construction of saddle insole for shoes in which a metallic reinforcement varyingin its degree of resiliency along the length thereof is `provided for aiding in the support of the inner portion of the arch ofthe foot.

A further object of my invention is to provide `an improved method of constructing a saddle insole by the insertion vof a preformed metallic `member which extends in a curved path about the vsaddle and is supported within the heel portion of the insole.

A still further object of my invention is to provide a construction of saddle insole in which a lining is secured over the saddle in such manner that continued wear of the shoe will not have a tendency of tearing the lining from the saddle.

Anotherobject of my invention is to provide a :construction of foot :support `which `,extends `under the bottom oi theheel of a shoe vand presents .a yieldable portion in a position adjacent the inner arch of the foot.

A still further object of my invention is to 'provide 'a construction of foot support which continues beyond the bottom of the heel and along the side oi the flanged portion or portions Yor counter for supporting the calcaneus, astragalus scaphoid, internal cuneiform, and great toe metatarsal bones.

Other and further objects of my invention reside in the construction of a saddle insole which greatly 'improves the comfort in the Wearing of shoes as set forth more fully in the specification Ihereinafter following by reference to the accompanying drawings, in which:

"Figure'l is a side elevationof my improved saddle insole shown in position in a shoe and illustrating the manner in `which the saddle insole supports the bones ofthe foot, particularly the calcaneus, 4astragalus, scaphoid, `internal cuneiform, :and the great `toe metatarsal bones; Fig. 2

I have developed the saddle insole of my invention Vin connection with the arch support covered by my Patent 1,777,440, dated October 7, 1930, and my application for Letters Patent Serial No, 753,045, filed November 114, 1934, `for Arch support for shoes, now Patent 2,085,374, dated June 29, 1937, and the saddle insole may be employed in combination with either of these arch supports, as indicated generally in Fig. 1, or in combination with any other suitable arch support. The purpose of my present invention is to improve the wearing comfort of shoes over the entire period of useful life thereof by providing a combination yieldable support for the bones of the foot, particularly the calcaneus, astragalus, scaphoid, internal cuneform, and the great toe metatarsal bones. The insole of my invention includes a saddle portion which is reinforced by a composite and yieldable strip member. The strip member is preformed to substantially correspond with the shape of the saddle insole. The

strip is constituted by a supporting portion and a resilient portion. 'Ihe supporting portion is somewhat more rigid than the resilient portion. The supporting portion may extend from under the insole or it may be secured between split portions of the insole secured to provide a support for the resilient strip portion. Rivets extend through the split portions of the heel of the insole and anchor the supporting portion of the reinforcing strip therein. The resilient portion of the strip is curved to conform with the general contour of the saddle portion of the insole and to provide the maximum yieldable support for the bones of the foot. The sock lining is stitched over the saddle portion thereby eliminating any tendency for the sock lining to become detached from the saddle insole or wrinkle or work loose and thereby become a source of discomfort in the wearing of the shoe.

My Patent 1,777,440, above referred to, shows an arch support devised to engage resiliently the vertical inner longitudinal arch of the foot embracing the bones from the calcaneus to the first metatarsal inclusive; and my Patent 2,085,374, also referred to7 discloses an arch support devised to support resiliently both the inner and outer vertical longitudinal arches of the foot, with a greater degree of resiliency provided in the support for lthe inner arch as compared with that for the outer arch. The arch support of my Patent 2,085,374, likewise embraces corresponding bones of the arches between the calcaneus and the i'lrst metatarsal. The reinforced saddle insole of my present invention, when used in combination with either of my patented arch supports in the manner shown in Fig. l, will therefore result in complete resilient support for all the bones of the arch in a manner not heretofore accomplished.

Referring to the drawings in more detail, I have shown the saddle insole I serving as a support for the bones of the foot within the shoe 2. For purposes of illustrating my invention, I have indicated the bones of the foot in dotted lines wherein reference character 3 designates the calcaneus, t the astragalusp the scaphoid, 6 the internal cuneiform, 'I the rst metatarsal, and 8 one of the phalanx bones. There are also various tendons and muscles which must be supported by the arch support 9 and the saddle insole I. The arch support 9 is illustrated as extending beneath the heel of the saddle insole. The saddle insole I is undercut peripherally as indicated at I vin Fig. 2 to provide connecting means for the welt and upper of the shoe. Ihe inner portion of the insole extends upwardly as indicated at Ia and forms a support for the foot. The upwardly extending portion Ia is shaped to conform with the lateral inner longitudinal arch of the foot, as shown clearly in Fig. 3, and provides a comfortable fit for supporting the lateral inner longitudinal arch. In order to insure the maximum possible support for the bones of the foot throughout the ordinary wear of the shoe, I provide a resilient metallic strip as a reinforcing member for the saddle insole. In order to support the strip, I either secure the strip under the heel portion of the saddle insole as indicated in Figs. 17 and i8 or I split the saddle insole at the heel portion thereof as indicated at II in Fig. 11 and between the split portions of the heel of the saddle insole, I introduce strip member I2. The strip member I2 is provided with apertures I4 through which rivets I extend for securing the strip member I2 in rigid position in the heel portion of the saddle insole. The strip I2 is bent upwardly in a plane which is substantially normal with respect to the plane of the portion of the strip member which is secured by rivets I5 inthe heel portion of the insole. The strip member I2 in addition to its vertically upward direction also extends in a substantially curved path conforming with the contour of the saddle portion of the insole. The upper extremity of the strip meme ber I2 provides an anchorage for the resilient strip I5. The resilient strip I6 is formed from spring steel adapted to maintain its resiliency throughout the normal wear of the shoe. A rigid connection is provided between the upper extremity of strip I2 and the lower extremity of strip i6 through four rivet members indicated at I l. The rivets I'I are so positioned that resilient strip I6 is substantially continuous with the more rigid strip I2. The resilient strip I6 is curved'to conform with the upper periphery of the saddle la. In order to provide a yieldable support for the saddle I a, I provide rivet apertures i8 in resilient strip I6 and pass rivets I9 through the apertures I8 in strip I6 through the saddle portion I a of the insole I. Any tendency ofthe saddle Ia to flatten out is continuously resisted by the coaction of the supporting strip I2 with the resilient strip I 6.

I may apply a covering material for the strips I 2 and I 6 which will prevent annoying sound such as squeaking as the shoe is subjected to strains and ystresses encountered in walking.

In order to improve the comfort in the wearing of shoes'const'ructed with the saddle insole of my invention, I provide a two-piece sock lining for the saddle insole as shown in Figs. 2-7. I do not rely upon the mere cementing of the sock lining 2U with respect to the saddle insole but positively stitch the sock lining 20 at its upper periphery as indicated at 2|. The threads 2I pass through the folded portion 22 of the sock lining 20 and secure the sock lining positively to the saddle portion Ia. The threads 2I pass through the upper peripheral edge of the saddle portion` Ia and serve to bind the sock lining directly to the saddle portion Ia. The downwardly depending peripheral edge of the folded portion 22 of .the sock lining is.cemented to the rear of the saddle portion Ia. The sock lining 20 may partially cover the saddle insole as represented in Figs. 8 and 16 and may be formed from a single sheet of any desired material. As indicated in Figs. 2 7, the sock lining may be formed in two parts, one part providing an envelope or casing for the saddle portion Ia, as shown at 20, including the folded portion 22, and the other part 24 forming a surface covering for the insole Ia. The surface covering 24 may extend only partially of the entire length of the insole I as indicated in Figs. 3, 4 and 5 wherein the surface covering 24 terminates along the line 25.

In'certain shoe constructions, I may desire to extend the surface covering 24 of the sock 1ining the entire length of the insole I as represented in Figs. 6 and 7.

As shown in Fig. 2, the folded over portion 22 of the sock lining 20 may terminate even with the strip IG. However, in a modified form of my invention, illustrated in Fig. 2a, an enlarged marginal portion 22a is provided and extends as a cover over the strip I5. The edge 23 of the enlarged marginal portion 22a may be secured by adhesive to the saddle portion Ia, and cut to conform with the shape of the strip I6. 'I'he linlng is stitched at 2l, as in the arrangement in Fig. 2.

The sock lining is so intimately connected with the saddle insole that there can be no wrinkling or loosening of the sock lining which is often a source of discomfort in shoes wherein sock linings are merely cemented in the shoe and not stitched therein as provided in the saddle insole of my invention.

The resilient strip which serves to maintain the shape and form of the saddle insole even under conditions of heavy stresses and strains is constructed of steel, the lower part I 2 which is of heavier material may be made of hard cold rolled or a tempered steel. The upper part Iii is high carbon spring steel which is highly tempered. By reason of the support provided b-y strip I2. the strip I6 is free to yield laterally to conform with the movement of the foot during walking. The resiliency of strip I6 is such that the saddle insole is continuously maintained in a position which affords maximum support for the bones of the foot.

Referring to Fig. 16, the saddle insole I is illustrated in perspective view having the vertical ly extending portion Ia covered by the sock lining 20 stitched at the periphery as indicated at 2|. The insole is indicated as perforated at |511 to allow rivets I5 to extend therethrough for the securing of the reinforcing member.

In the perspective view in Fig. 17, I have shown the saddle insole in a position reversed with respect to the position illustrated in Fig. 16 and illustrating the manner in which the resilient strip I6 is shaped to conform with the contour of the peripheral edge of the upwardly extending portion of the saddle insole la. This View also illustrates the manner in which the more rigid strip I2 extends beneath the heel portion of the saddle insole and is secured thereto by rivets l5.

In Fig. 18, I have shown the saddle insole viewed from the bottom and looking upwardly showing the more rigid strip I2 riveted at I5 beneath the heel portion of the saddle'insole and secured at I'I to the more resilient strip I 5 and illustrating the manner in which the more resilient strip I6 serves as a support for the outer side wall of the vertically extending portion of the saddle insole at Ia.

Heretofore. the several views have shown invention as applied to a saddle insole which is initially built into the shoe. I may construct a separate insert for a shoe embodying al1 of the desirable qualities of my invention so that the support may be applied to existing types of shoes without modication of the shoe structure per se. Figs. 19 and 20 illustrate my invention as applied to a separate insert for shoes. A, sole and heel portion for the separate insert is provided at 25 having a vertically extending side wall portion the forward edge of the portion 26 is chamfered i.

as at 28 to conform with the insole of the shoe.

If desired, the insert may be made full length,v

corresponding to the insole of the shoe.

I have described my invention applied both as a structural improvement in shoes and as an insert for existing type shoes for imparting benecial effects to the feet and insuring greater wearing comfort. I realize that changes in the details of arrangement may be made and I desire that it be understood that modifications of my invention may be made and that all such modifications are included within the scope of my invention and that no limitations upon my invention are intended except as may be imposed by the following claims.
