SHOE FOR FLAT-FOOTED PERSONS.

Specification of Letters Patent.

Patented July 4., 1911.

Application filed December 8, 1910. Serial no. 596,184.

This invention relates to shoes for flatfooted persons, in which the parts for sup porting the arch of the foot are permanent and fixed elements and not removable inserted pieces; and, as also distinguished from such known forms of construction,

the advantages of permanent support are combined with those of non-conspicuousness .and elegance. For thepurpose of enabling production to be effected on a large scale and so that the shoes for flat-footedpersons can be easily fitted to particular individuals, the arch of the-sole and the side curve of the foot are provided for as is well known by' two independent supporting devices. The arch of the sole is obtained in the known manner by means of a wide spring plate. sltuated under the insole, and which may be so stout and yet so arranged that its presence does not impart any awkward appearance to the shoe. A far more dilficult task is that of cleverly arranging and forming the support for the side curve of the foot, and this is the special object of the present invention.

In the. drawing Figure 1 represents the under side of the insole with supporting device b lying thereon for the side curve of the foot. Fig. 2 is a similar illustration with the supporting device a for the arch of the sole or footin the direction of the line of its longitudinal center. Fig. 3 is a transverse section through the insole and the supporting device a lying between the insole and the outer sole or tread. Fig. 4 is a fragmentary bottom plan view of the insole, the supporting device and plate being removed therefrom.

For the purpose of clearness different dimensions are shown exceedingly large.

The essential feature of the invention is that the plate I) provided for supporting the side-curve of the foot is held by a number of narrow stays a, which coming through between the different stitches in the edge.

of the insole d and outer sole 6 are arranged between these two. It has been found very practicable to form excisions in the r inforced insole, into which the stays 0 are let,

for the purpose of preventing any undesirablebulging out of the insole d or the formation of creases in the upper leather and injurious strain in the seam.

' A really secure hold for the side curve of the foot is not obtained by different teeth or prongs projecting below the sole, but only by a solid plate adapted as far as possible to a proper shape of foot, and suitably made of sheet steel. This plate 6, according to the invention is supported by a number of diverging stays a, which pass through between the different stitches in the insole. The di vergence of the stays 0 requires different degrees of curvature for thedifferent stays 0, owing to which the plate 6 obtains greater support than if the curvature were equally great in all the stays. The principal cause of the satisfactory hold ofthe supportingdevice I) is however the divergence of the stays a inasmuch as thereby the stays are prevented from slipping out orslipping in i the gaps in the seams. In consequence of into the gaps from. outside, but must be inserted before the insole (Z 'and the outer sole e are stitched together. As is well known .the insole d is thickened, in order that suffi- 'ciently strong leather material may be provided for stitching it to the'outer sole e. By the interposition of the'supporting decisions the stays c are let. The sole consequently, in spite of'the insertion of the supporting device I), is not thickened, so that the shoe for the flat-footed person does not differ externally from ordinary shoes.

The supporting device I) is held particularly secure in its right, position if different stays are so formed that they extend partially below the heel and partially below the base of the small toe. As the bodily weight of a human being rests for the most part on these points in the sole, the stays b are clearly more firmly pressed down, than if the stays lay only belowthe less strained, softer middle part of thefoot.

What I claim as my invention, and desire no All the spreading outofthe stays c the supporting device Z) cannot be subsequently pushed thereof. and having a portion extending up on the inner side of the shoe, and diverging stays carried by the plate and disposed so that one of the stays is disposed beneath the heel of the shoe and another of the stays projects adjacent the base of the small toe of the wearer when the shoe is in use.

2. In a shoe, a plate for supporting the arch of the foot at the inner side thereof disposed adjacent the arch, and diverging stays carried by the plate and extending under the insole of the shoe, said insole having a reinforced stitching rib formed With openings to receive the stays, and means to secure the plate between the insole and outer sole.

3. In a shoe, a plate curved to conformably engage the arch of the shoe at the inner side thereof and formed with a series of integral spaced stays which extend under the insole between the latter and the outer sole, the stays at one end of the at the opposite end of the plate extending toward the toe of the shoe on the outer side thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
