Description:

This invention relates to improvements in shoe constructions, and has more particular reference to an improved shoe construction embodying a built-in adjustable arch-supporting structure adapted for supporting fallen arches and protecting high arches by preventing them from breaking down.

A more specific object of the present invention is to provide an improved arch-supporting shoe of the above kind having an improved insole construction affording an arch-supporting structure adapted to accommodate a supplemental arch-supporting insert so that the arch-supporting structure may be accurately adjusted both longitudinally and transversely of the shoe to provide the proper position and form to comfortably fit and properly support the arch in accordance with the individual requirements of each case.

A still further object of the present invention is to provide a shoe having an arch-supporting structure of the above kind which is extremely simple and durable, and wherein the supplemental arch-supporting insert is of such form and allows such substantially universal adjustment as to insure efficient results.

The present invention consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings, and claimed.

In the drawings: Figure 1 is a longitudinal vertical sectional view of an arch-supporting shoe constructed in accordance with the present invention.

Figure 2 is a horizontal sectional view thereof taken on the plane of line 2-2 of Figure 1.

Figure 3 is a transverse vertical section taken on the plane of line 3-3 of Figure 1.

Figure 4 is a bottom plan view of the supplemental arch-supporting insert.

Figure 5 is a bottom plan view of the main or upper member or section of the insole.

Figure 6 is a similar view of the secondary or lower member or section of said insole; and Figure 7 is a longitudinal section of the supplemental arch-supporting insert taken on line 7-7 of Figure 4.

The present Invention is illustrated in connection with a shoe of the welt type, including an ordinary or any preferred upper 5, an outsole 6, a welt 7 stitched to and on the margin of the outsole 6 as at 8, and a heel 9.

In accordance with the present invention, the shoe is provided with an insole comprising a main 66 or upper member or section 10 and a secondary or lower member or section II. The main or upper insole section 10 is of full length and slightly longer than usual, for a purpose which will be presently made apparent. Also, this main or upper insole 6 is provided in its lower face o around the fore part with a marginal upwardly and outwardly inclined stitch-receiving channel 12 which terminates at each side just forward of the shank portion or just rearwardly of the ball of the sole. The secondary or lower insole section II is shaped and proportioned to substantially conform to the rear part of the main section 10 which is composed of a shank portion 13 and a heel portion 14. Also, the secondary or lower insole section II is scarfed or beveled as at 15 throughout the marginal edges thereof so as to avoid excessive bulk where these edges overlie the inner edge portions of the welt 7, the marginal edges of the main or upper insole section 10 being similarly scarfed or beveled as at 16 for a similar purpose and to give upwardly slightly to afford the proper shape to the upper 5 where it passes upwardly around the marginal edges of the insole sections 10 and 1I. Entirely along the opposite side edges and around the rear or heel edge of said secondary or lower insole section I, the latter is provided in its lower face with an upwardly and outwardly inclined stitchreceiving channel 17 which, when the upper and lower sections of the insole are assembled, forms a continuation of the channel 12 in the upper section 10. It will be noted that the welt 7 extends entirely around the marginal edge of the outer sole 6, the portion of the upper inner sole section 10 which is provided with the channel 12 being stitched throughout the channel as at 18 to the welt 7 at the fore part of the sole. In a like manner, the lower insole section II is stitched throughout its channel 17 along its sides and around its rear or heel edge to the welt 7, as at 19, at the rear part of the sole. The heel portion of the main or upper insole section 10 is then permanently secured to the heel portion of the lower insole section II by suitable means, such as the nails 20 which fasten the heel 9 to the heel portion of the outer sole 6, and due to the fact that the upper insole section 10 is slightly longer than usual, the shank portion 13 is thereby bulged upwardly as shown clearly in Figure 1 so as to form a pocket between the shank portions of the insole sections 10 and 11, throughout the arch portion of the shoe and open at both sides -of the latter.

Removably positioned within the pocket; or space thus provided between the shank portions of the insole sections 10 and II is the main or body portion of a supplemental arch supporting insert 21. This insert 21 is preferably formed of a piece of soft and pliable leather with its body portion of a length somewhat less than the length of the pocket or space provided between the shank portions of the insole sections, as illustrated clearly in Figure 1, thereby providing material adjustment of the insert longitudinally of the shoe, in addition to the fact that the insert is adjustable laterally of the shoe by a transverse sliding movement and by limited turning of the insert about a vertical axis. In this way, the high point of the upwardly bulged shank portion 13 of the upper insole section 10 may be adjusted forwardly or rearwardly of the shoe and transversely thereof with corresponding modification of the slant and form of the portion 13 which directly engages the arch of the foot.

This will be more clearly understood when it is made apparent that the body portion of the insert 21 is provided with-a forward limited area 22 of maximum thickness, the remainder of the insert being scarfed or beveled to nearly a feather edge outwardly from this area 22 of maximum thickness. The forward end portion of the insert 21 is also narrowed and rounded as at 23 to properly conform to the forward portion of the arch of the foot, as well as to facilitate the turning adjustment of the insert about a vertical axis.

Formed on the rear portion of insert 21 is a relatively large rounded lateral tongue or extension 24 which is curved outwardly and upwardly to extend upwardly against the upper 5 of the shoe at the inner side of the arch and thereby afford proper support for the arch of the foot at this side where the arch is highest. Naturally, when the shoe is laced or otherwise fastened on the foot the upper tends to raise this extension or tongue 24 and the adjacent inner side portion of the bulged shank 13 of the upper insole section 10, so that it will.contact and properly support the adjacent portion of the arch of the foot. From this description, it should be apparent that longitudinal transverse and limited rotatable adjustment of the insert will accommodate the arch support to arches of various forms and types so as to properly support them and at the same time insure complete comfort to the wearer. It will of course be understood that, as illustrated, the upper will be secured by the stitching at 18 and 19 between the welt 7 and the adjacent marginal portions of the insole sections 10 and I . From the foregoing description, it will be seen that the present invention provides an extremely simple shoe construction, wherein an arch support is incorporated in the structure of the shoe, and wherein the arch support is so constituted and adjustable that it may be readily and most perfectly adapted to varying types of arches so as to be uniformly efficient and comfortable. The necessary adjustments may be effected at the time when the shoes are sold to a purchaser, either for the purpose of correcting faulty arches or to prevent fallen arches. Obviously, insert 21 may be available in different sizes and slightly modified forms so as to increase the possible range of arch adjustment beyond that afforded by mere adjustment of the insert itself to different positions within the pocket or space provided between the shank portions of the insole sections.

Minor changes in the specific form of parts and details of construction illustrated and described are contemplated within the scope of the invention as claimed.

What I claim as new is: In a shoe having a built-in adjustable arch support, the combination of an outer sole, a welt stitched on and extending throughout the margin of said outer sole, an insole comprising an upper main section and a lower secondary section, an upper secured between said welt and said insole, said main insole .section extending the full length of the outer sole and having only its fore part sewed at the front and sides to the welt, said secondary insole section being sewed to the welt along its side and rear edges and terminating at its forward end substantially at the rear line of the ball of the sole, said main insole section further being slightly greater than usual length and being secured at its heel portion to the heel portion of the secondary insole section so that the shank portion of said main insole section is bulged upwardly to form a permanent yieldable arch support and to provide a space between the shank portions of said insole sections open at'both sides of the shoe, and a supplemental arch support adjusting insert removably positioned in said space between the shank portions of the insole sections, said insert being of lesser length than said space and adapted for adjustment in the latter both transversely and longitudinally of the shoe, said insert further having a lateral extension on the inner side of the rear portion thereof curved and projecting outwardly and upwardly beyond the inner sides of the shank portions of the insole sections to raise the inner side portion of said permanent arch support and furnish additional support for the inner side of the arch when the shoe is fastened on the foot, said extension also providing means to facilitate removal or adjustment of said insert.
