Another object of this invention is to provide The crepe rubber is frequently very flexible and 5 a rubber sponge shoe having a reenforced cork it is desirable to provide a cork insole 16 which and crepe rubber sole which has the appearance cooperates with the side walls 10a and the inner of a. welt and which has a more eifective manner side of the crepe rubber sole 12 to form a'stiffenof securing the upper to the sole by cementing ing but comfortable lining. Gussets 18' of crepe along the top face of the sole and inner side of or vulcanized rubber are preferably fitted along 50 the upper to give a better reenforcement. the corner seam between the cork sole inner-liner Another object of this invention is to provide 16 and the interior of the side walls 10a througha shoe having the strength, shape, and appearout their entire length and act as reenforcing eleance of a vulcanized rubber and the comfort, and ments along the corner seam of the sole as they porosity of sponge rubber. are preferably cemented to the cork sole and to 55 Other objects of this invention will appear from the side walls 10a. The side walls are thus kept in shape in a much more satisfactory manner and do not tear out at the seam.

If desired reenforcing elements 20, of crepe or vulcanized rubber, may be provided along the tip of the shoe on the inside and connect at the top 10b of the instep portion with cross reenforcing strips 22 which latter strips extend along the edge of the opening through which the foot is projected. These latterstrips 22 form with the reenforcing strips 20 of the T shape reenforcing element of the entire front of the shoe.

The reenforcing strips 20 and 22 are cemented or otherwise secured to the sponge rubber forming the upper and the strips are also cemented to the sole to'which they extend. The corner gusset 18 also is cemented to the strips as well as the sole and thus the strips act as a skeleton reenforcement of the shoe. Furthermore, as the strips are of crepe or vulcanized rubber, they are flexible and elastic but not as expansible as the sponge rubber. They tend to hold their shape and also tend to prevent bulging or tearing of the sponge rubber when the foot is inserted in the shoe.

Such a shoe is extremely soft, flexible and com fortable on the foot. The sponge rubber is porous permitting ample ventilation of the shoe and yet due to the cork inner-liner and the crepe rubber sole the shoe substantially affords a good walking surface. The sole does not become deformed as it is substantially incompressible but is nevertheless equally soft and comfortable on the foot. The inner-soles are shaped to the foot and extend along the entire inner surface of the shoe and fit within the space between the sides 10a of the shoe 10. Inasmuch as the crepe rubber sole 12 extends upward along the sides 12 and as the gussets 18 also extend upward the shoe is completely reenforced and sides cannot be torn away from the sole portion. The shoe is thus of considerable strength due to its reenforcement. The strips 20 and 22 aid in accomplishing this result. If desired, an additional strip of crepe or vulcanized rubber may be incorporated on the upper edge of the opening in the upper as is shown at 49 in Figures 5 and 6 and this additionally reenforces the shoe and causes it to cling to the foot.

A slightly modified form of embodiment of the shoe is shown in Figure 4. The side wall 10a of the upper is adapted to be secured by cementing or otherwise to a sole 32 of crepe or of vulcanized rubber which has an upwardly extending portion 32a along the edge of the sole 32. The crepe rubber sole then has an integral internally extending portion 32b substantially parallel with the sole 32 and extending over the cork inner-liner 16. Co-extensive with the internally extending portion 32b of the crepe rubber sole is a further upwardly extending portion 320 which co-operates with the inside of the side walls 10a to which the crepe or vulcanized rubber is cemented. There are several advantages to such a construction among which are a greatly increased cementing or contact area, both along the reversely extending portion 32b and along the area between the upstanding portion 320 and the side wall 10a. Furthermore, the shoe has a better appearance, the joint appearing as a welt as in the usual common type of shoe and therefore has less the appearance of the rubber type of shoe. It is to be noted that the crepe rubber 32 being in most cases extremely thin is unsatisfactory as an entire sole, making the use of the cork liner 16 of great importance to increase the comfort of the shoe in walking. The inner-liner 16 however, may be of cork, rubber, imitation felt, linoleum or other suitable, preferably waterproof, substances and may have a cloth or other smooth foot contactin Figures 5, 6, and 7. The shoe 40 is provided with a shaped sponge rubber upper 41 on a vulcanized rubber sole 42, the sole 42 having an extension 43 to reenforce the toe portion of the upper 41. A heel 44 may be integral with the sole or separately attached thereto, and as shown in Figure 5 an extension 45 of vulcanized rubber extends from the rearward edge of the heel up the heel portion 46 of the upperacross the top of the upper and down again along the inside 47 of the heel portion of the upper, and finally is anchored under the inner-liner 48. The inner-liner 48 is preferably of cloth, or cork and extends throughout the inner bottom portion of the shoe forming a continuous gusset 48a along the side walls, the toe portion and the heel portion of the upper. This inner-liner 48 which might be made of rubberized cloth or suitable other material which is substantially incompressible and yet substantially flexible is thus adapted to form the foot contacting portion of the sole and will additionally reenforce the contact between the walls 46 of the sponge rubber upper 41 and the sole 42.

From an inspection of Figure 6, it will be noted that the sole 42 is provided with integral extensions 42a which extend beyond the top of the sole 42 an amount sufficient to engage the side walls 46 of the sponge rubber upper through a portion of their length. This amount is sufficient to permit cementing of the side walls of the upper to the edge portion 42b and extensions 42a of the sole and as the upper is reenforced on the outside by these extensions and also reenforced on the inside by the inner-liner 48 which extends upward along the surface 48a to which the side walls 46 are also cemented but to a height slight- 1y less than that of the extensions 42a on the outside the shoe will be extremely rigid and will retain its shape. A reenforcing band 49 surrounds the edge of the opening in the upper and this band 49 may be preferably made of crepe or vulcanized rubber, or other material which is less expansible than sponge rubber and adapted to hold the foot firmly within the shoe.

An additional band 50 is not only ornamental, but is also desirable from the standpoint of strengthening the front part of the shoe, although this may be omitted.

The shoe shown in Figures 5, 6, and '7 is thus reenforced at the points of greatest stress. In inserting the foot it is natural to pull the shoe on through the heel portion and with the use of the straps 45 and 47 which is integral with the sole on the outside, and which is anchored under the inner sole on the inside, the shoe may be very effectively drawn onto the foot. The straps 45-47 also cover the seamed portion of the sponge rubber upper 40, which seam is located at the back of the shoe and thus reenforces this seam. When the foot is in the shoe the reenforced toe portion 1 foot. The band 49 around the opening also engages the footand thus aids in on the foot. 1 I

In all of the constructionsshown, the skin is preferably removed from the spongerubber sec-' tions both on the exterior and interior. This provides ample porosity and prevents the foot from perspiring and becoming uncomfortable and hot. The sponge rubber that is used is particularly po-' rous, not only permitting the air to pass through it but also facilitating cleaning when such is desired. The sole inner-liner is preferably smooth surfaced to permit the foot to slide therein with the minimum of friction. v

It is obvious that the inner-lining may be made of cloth fabric, gum rubber, light leather, or other material which is pliable, although a cork compound filler with a fabric cover is found most satisfactory. Sponge rubber is used as far as possible for the purpose of reducing the weight, increasing the porosity and enhancing the beauty of the shoe. The crepe rubber, or vulcanized rubber for the sole and heel, and for such decorations in the nature of toe and instep reenforcement are preferably used, because they, hold their shape better and form a stiffer and more satisfactory walking contact. The sole is shaped to the foot making a more stylish and more comfortable shoe. The flange is integral with the sole to increase the reenforcing strength between the sole and upper, and to prevent accidental tearing of the material.
