Abstract
Abstract A tennis shoe and a sole therefor having a longer life than a conventional tennis shoe. The Sole has an upwardly extending side portion in a toe region and inside ball-of-the-foot region which is thicker at the junction of the side portion with the bottom por-tion of the sole than the junction of the up upwardly ex-tending side portion with the bottom portion along the remainder of the side boundary of the sole.
Description
lOS0263 This invention relates to soles for tennis shoes and to tennis shoes.
Due to excessive dragging of the toe during the act of serving~ the toe area of the outsole and inside ball-of-the-foot region are areas of excessive wear, causing tennis shoes of the prior art to have shortened llves.
It is an ob~ect of the present invention, there-fore, to provide a new and improved sole for a tennis shoe which avoids one or more disadvantages of prior ` -such soles.
It is another object of the invention to pro-vide a new and improved sole for a tennis shoe which provides a~ increased life span for the tennis shoe.
It is another ob~ect of the invention to provide a new and improved tenniæ shoe which avoids one or more disadvantages of prior such shoes.
In accordance with the invention, a sole for a t tennis shoe comprises an elaætomeric body having an elongated bottom portion and having an upwardly extending ' side portion having a given horizontal thickness at the ~unction thereof with said bottom portion along the side boundary of the aforesaid body except in a toe region and base of the large toe xegion, the upwardly extending side portion in said toe region and base of the large toe region being horizontally thicker at the ~unction thexeof with the bottom portion than the aforesaid given thickness.
Also in accordance with the invention, a tennis shoe comprises an upper, an insole secured to said 3 upper, a ~oxing secured to said upper, and an A
outsole secured to the insole and the foxing and com-prising an elastomeric body having an elongated bottom portion and having an upwardly extending side portion having a given horizontal thickness at the junction thereof with the bottom portion along the side boundary of the afore-said body except in a toe region and base of the large toe -region, the upwardly extending side portion in said toe ~`
region and base of the large toe region being horizontally thicker at the ~unction thereof with the bo~tom portion than the aforesaid given thickness.
For a better understanding of the present in-vention, together with other and further objects thereof, reference is made to the following description, taken in connectlon with the accompanying drawlngs, and ~5 i~s scope will be pointed out in the appended claims.
Referring now to the drawings:
Fig. 1 is a bottom plan view of a sole constructed in accordance with the invention;
Fig. 2a is a sectional view of the Fig. 1 sole, taken along the line 2a-2a of Fig. 1, Fig. 2b is a sectional view of the Fig. 1 sole, ta~en along the line 2b-2b of Fig. l; and Fig. 3 is a sectional view of a tennis shoe con-structed in accordance with the invention.
Referring now more particularly to ~igs. 1, 2a and 2b of the drawings, a sole 10 for a tennis shoe com-prises an elastomeric ~ody having an elongated bottom portion ~1 and having an upwardly extending side portion 12 having a given thickness at the junction thereof 3~ wi~h the bottom portion 11 along the major portion of

For a better understanding of the present in-vention, together with other and further objects thereof, reference is made to the following description, taken in connectlon with the accompanying drawlngs, and ~5 i~s scope will be pointed out in the appended claims.
Referring now to the drawings:
Fig. 1 is a bottom plan view of a sole constructed in accordance with the invention;
Fig. 2a is a sectional view of the Fig. 1 sole, taken along the line 2a-2a of Fig. 1, Fig. 2b is a sectional view of the Fig. 1 sole, ta~en along the line 2b-2b of Fig. l; and Fig. 3 is a sectional view of a tennis shoe con-structed in accordance with the invention.
Referring now more particularly to ~igs. 1, 2a and 2b of the drawings, a sole 10 for a tennis shoe com-prises an elastomeric ~ody having an elongated bottom portion ~1 and having an upwardly extending side portion 12 having a given thickness at the junction thereof 3~ wi~h the bottom portion 11 along the major portion of
-2-lOSOZ63 the side boundary of the body. The sole 10 may be of natural or synthetic elastomer but preferably is of expanded polyurethane of a formulation set forth hereinafter.
The upwardly extending side portion 12 in a toe region and inside ball-of-the-foot region 12a is thicker at the junct-ion thereof with the bottom portion than the given thickness of the remainder of the upwardly extend~ng side portion 12. More particularly, the upwardly extending side portion 12 in the toe region and inside ball-of-the-foot region 12a preferably is thicker by about 1/8 inch at the junction thereof with the bottom portion than the given thickness of the remainder of the upwardly extending side portion 12, as represented in Fig. 2.
The thickened side portion is repreeented in Fig. 1. by the dis-tance between the broken line 12b and the outer edge of the region 12a.
The thickened side portion 12a preferably is thicker than the remainder of the side portion 12 for at least about 1/16 inch above the junction of the side portion with the bottom portion 11~
The bottom portion 11 has a rough surface area in the toe and inside ball-of-the-foot region, as represented by the area 13 in Fig. 1. The bottom portion in the area 13 is tapered to be thicker at the outer edge of the toe and inside ball-of-the-foot reg~on than the remainder of the sole, as represented in Figs..2a and 2b. The bottom portion in the area 13 prefer-ably is tapered to be about 1/16 inch thicker at the outer edge of the toe and inside ball-of-the-foot region than 1050263 `
the remainder o~ the sole.
The sole 10 has slits 14 in a herring bone pattern which are located in the ball-of-the-foot area and across the heel area, providing the necessary traction to the wearer. The shank area of the sole has horizontal bars 15, which provide lateral stability for the sole.
The sole 10 preferably is ~ormed by casting into a mold but may be formed by injection molding or any other suitable method.
The polyurethane recipe for the sole 10 preferably is as follows:

The upwardly extending side portion 12 in a toe region and inside ball-of-the-foot region 12a is thicker at the junct-ion thereof with the bottom portion than the given thickness of the remainder of the upwardly extend~ng side portion 12. More particularly, the upwardly extending side portion 12 in the toe region and inside ball-of-the-foot region 12a preferably is thicker by about 1/8 inch at the junction thereof with the bottom portion than the given thickness of the remainder of the upwardly extending side portion 12, as represented in Fig. 2.
The thickened side portion is repreeented in Fig. 1. by the dis-tance between the broken line 12b and the outer edge of the region 12a.

a trademark Other materials such as rubber or plastic based materials can also be used for the sole 10.
As represented in Fig. 3, which is a cross section of a tennis shoe constructed in accordance with the invention, the outsole 10 may be attached by a conventional rubber binder 16 to the insole 17 which may be of any suitable expan~ed elastomer material. The outsole 10 also is attached to an upper 19 of conventional material such as fabric or leather using a suitable adhesive. An elastomer foxing 18 is attached to upper 19 and to the outsole 10 using a common adhesive for this purpose. Also, a fabric-reinforced or friction foxing is attached to foxing 18 and outsole 10 using a suitable adhesive. An elastomeric bumper 21 extend~ng around the toe and ball of-the-foot region is attached to the foxings 18 and 20. The upwardly extending side portion 12 may be buffed to improve adhesion of the various members of the shoe thereto.
From the foregoing description it will be seen that the thicker upwardly extending side portion 12a provides a longer life for the sole 10 and for the tennis shoe, giving increased wear in the critical area of the shoe when the toe of the shoe ~s dragged during the act of serving. Also, the increased thickness of the bottom portion of the sole 10 in the region 13 causes the sole 10 and the tennis shoe to have a longer life.
While there has been described what at present is belie-ved to be the preferred embodiment of this invention, it will be obvious to those skilled in-the art that various changes and 1~50263 modifications may be made therein without departing from the invention, and it is, therefore, aimed to cover all such changes and modifications as fall within the true spirit and scope of the invention.
