4 Claims.

My invention relates to a novel combination of insole and insert and more particularly my invention relates to an insole having an opening in the forepart thereof, said opening containing an insert of fibrous material so that the insole is rendered flexible, comfortable and its wearing qualities are improved.

It is the object of the present invention to provide a novel resilient combination of insole and insert. v

It is a further object of the present invention to provide a flexible insole.

It is a further object of the present invention to provide an insole which permits and provides the free circulation of air in the shoe.

It is a further object of the present invention to provide a novel insole having increased cushioning properties for the foot.

These objects I accomplish by cutting out as by stamping an opening in the forepart of an insole and securing in this opening an insert comprising an over-all portion including a lap having secured thereto a fibrous material adapted to provide resilience, the fibrous material being particularly shaped to increase circulation of air through the shoe and extend the wearing properties of the material.

The drawing and the specific description thereof which here follows will more particularly show the manner in which the objects of my invention are accomplished.

Figure 1 is a bottom view of the insole-insert combination of my invention.

Figure 2 is a cross section taken along the line 2-2 of Figure 1.

Figure 3 is a bottom view of a modified form of the insole-insert combination of my invention.

Figure 4 is a cross section of a modified form of my invention.

Referring now more specifically to Figure l I show an insole I having an opening defined by the line ll in the forepart thereof. Over this opening is disposed an insert cover comprising a fabric lap portion I2 which extends over a substantial area of the insole and is secured to the insole by the stitching I4 in the area 13 which surrounds the opening I I and it also is secured to the insert l5 by means of the stitching 16.

As will be more particularly seen from an examination of both Figures 1 and 2, the insert portion 45 comprises a fibrous material which has been cross meshed with lines of stitching I6 which divide the fibrous material of the insert 15 into a plurality of adjacent downwardly projecting tufted elements l1. Through each of 01. 36-3) l V these tufted elements extends the perforation I9 and I additionally provide perforations 20. which extend through the insole and the lap portion l3 in the marginal areas around the opening II.

By reason of the nature of the tufted effect obtained on the bottom of the insert by cross stitching of fibrous material thereof, I provide for pumping and circulation of air from the openings 22 which lie between the insert l5 and the outsole 23. On the fabric l2 and secured thereto by stitching 25 is a metatarsal arch support 26 which also may comprise some resilient fibrous material. Alternatively to only fibrous material, the. insert may be made of fibrous material, such as felt, etc., impregnated with latex.

In Figure 3 I show a modified form of my invention comprising an insole 30 having in the forepart thereof an opening defined by 3! in which opening is disposed an insert comprising a lap portion 32 and an insert portion 39. The lap portion 32 is secured to the insole 30 by stitching 33 and 34 and the insert may be strengthened by additional provision of the stitching 35. The insert 39 as will be particularly noted from an examination of Figure 4, comprises layers of fibrous material such as felt which extend into the opening 3|. Perforations 36 extend through the insert proper and perforations 31 extend through the lap portion and the insole. The insole and insert lay directly inrcontact with an outsole 38 and provide a resilient inner portion between the foot and the outsole.

The felt-like laminated formation of the insert makes it possible to form the insert in the form of a lap and central portion by simply cutting away a number of layers in the marginal portion thereof. The laminated felt-like material is resilient and since it is reinforced with the stitching 35 has a relatively long life.

In both forms of'my invention, that shown in Figure l and that shown in Figures 3 and 4, the

portion at the center of the forepart is thicker than the combined thickness of the insole and the lap portion. This is to provide a ball cushion support.

Various other modifications of my invention will suggest themselves to those skilled in the art. I accordingly desire that in construing the breadth of the appended claims that they shall not be limited to the specific details shown and described in connection with the above explanation.

I claim:

1. In combination an insole and an insert, said insole having an opening in the forepart thereof,

said insert comprising a fibrous material secured to an insert cover by cross mesh stitching so as to produce a quilt effect on the bottom of the fibrous portion to provide air channels for the circulation of air, said insert cover being secured to said insole, and perforations through said fibrous insert, said fibrous insert being thicker than said insole.

2. In combination an insole and an insert, said insole having anropening in thejorepart thereof, said insert, c omp'rising;a fibrous material secured to an insert cover by cross mesh stitching so as to produce a quilt effect on the bottom of the fibrous portion to provide air channels for the circulation of air, said insert cover being secured to said insole, and perforations through said fibrous insert, said fibrous material being impregnated with latex.

3. In combination an insole and an insert, said insole having an opening in the forepart thereof,

said insert comprising a resilient fibrous portion adapted to fit into said opening, said resilient fibrous portion being positively secured to a cover portion by cross mesh stitching so as to produce a quilt effect on the bottom of the fibrous portion to provide air channels for circulation of air, said cover portion extending over said opening and over the adjacent marginal portions of said insole, said cover portion being secured to said insole.

4. In combination an insole and an insert, said insole having an opening in the forepart thereof, said insert comprising a resilient fibrous portion adapted to fit into said opening, said resilient fibrous portion being positively secured to a cover portion by cross mesh stitching so as to produce a quilt effect on the bottom of the fibrous portion to provide air channels for the circulation of air,

said cover portion extending over said opening and over saidadjacent marginal portions of said insole, said cover portion being secured to said insole; and a metatarsal arch support secured to said cover portion in the metatarsal area.

I I MEYER MARGOLIN.
