Application February 15, 1954, Serial No. 410,325

1 Claim. (Cl. 128-453) The present invention relates generally to footwear and more particularly to a callus eradicator.

The primary object of this invention is to provide means for utilizing moisture in the treatment and cure of calluses. To this end I provide an element to be worn by the patient, this element having a moisture impervious portion which retains the natural perspiration moisture of the foot to soften calluses.

Another object of this invention is to provide a callus eradicator which is of light, thin construction and may be worn comfortably under stockings and shoes.

Another object of this invention is to provide a callus eradicator which is easily cleaned and may be replaced on the foot very shortly after cleaning.

Another object of this invention is to provide a callus eradicator which is adapted for fabrication from many different materials, so that the choice of materials can be according to the dictates of availability and price considerations, the exact sizes and proportions being matters easily determined to suit particular conditions and needs.

Another object of this invention is to provide a callus eradicator which is inexpensive and practicable to manufacture.

Finally, it is an object to provide a callus eradicator of the aforementioned character which is simple, safe and convenient to use, and which will give generally efficient and durable service.

With these and other objects definitely in view, this invention consists in the novel construction, combination and arrangement of elements and portions, as will be hereinafter fully described in the specification, particularly pointed out in the claim, and illustrated in the drawing which forms a material part of this disclosure and wherein similar characters of reference indicate similar or identical elements and portions throughout the specification and throughout the views of the drawing, and in which:

Fig. l is a side elevation view of the callus eradicator, a foot being shown in broken line for purposes of illustration.

Fig. 2 is a top plan view of the eradicator in position on a foot.

Fig. 3 is an enlarged sectional view taken on the line 3-3 of Fig. 2.

Referring now to the drawing, the callus eradicator comprises a wide band it) of distinctive shape to fit the forepart of a foot and having a foot opening 12 and a toe opening 14. The band extends over the toes and has a lower rearwardly extending portion 15 which reaches well underneath the arch of the foot. The foot opening 12 extends from the lower rear edge 16 of the band to the upper portion or toe cap 18. The band 10 is shaped so that the lower rear edge 16 is beneath the instep of the foot as shown in Fig. 1. The edge 20 of the foot opening 12 is selveged to prevent fraying and is contoured to fit the foot comfortably.

The lower forward portion 22 of the band 10 is made moisture proof by addition thereto of moisture impervious plastic or the equivalent, the plastic either being adhered to the inside of the band or the material of the band being impregnated with plastic by dipping. The

plastic is probably best disposed as shown in Fig. 3 with the plastic constituting a layer inside the band and also surrounding the individual threads in the lower forward part of the band 10, so that the plastic remains in place without resort to the use of adhesives. The inner surface of the portion 22 is smooth to fit closely against the foot, said portion extending longitudinally from the toe opening 14 to a point slightly behind the ball of the foot, the rear edge thereof being indicated at 24. The portion 22 extends for a short distance up both sides of the band 10 to ensure that the entire ball of the foot is covered.

The toe cap 18 is short in length so that the eradicator may be worn under low cut pumps or similar shoes and be completely concealed. The lower rear edge 16 and the edge 26 of the toe opening 14 are, of course, selvedged to prevent fraying. The band 10 may be of knitted construction and must be light in Weight, material such as that used for conventional nylon stockings or the like being ideally suited for the purpose. This type of material is extremely elastic so that the eradicator will stretch to fit the foot snugly without slipping.

It is well known that the majority of calluses form on the ball of the foot where the greater part of the body weight is borne. When the eradicator is worn, the plastic portion 22 retains the perspiration or natural moisture of the foot, the moisture also serving to adhere the portion more firmly to the foot to ensure an effective seal. The trapped moisture softens the calluses considerably, so that when the eradicator is removed the now softened tissue may be easily removed. It has been found that the eradicator may be worn for long periods and may be conveniently worn at night while asleep to prevent the calluses from hardening and causing discomfort.

The eradicator is easily washed and may be dried and replaced on the foot within a few minutes, the light weight material being extremely quick drying. Certain prior types of pads used as callus eradicators require the use of medication to perform their task. The eradicator described herein requires no medication of any kind and thus is not subject to staining, the cleaning process being limited to a simple washing.

The knitted band reinforces the plastic portion 22 and prevents it from stretching permanently out of shape and also holds it in the correct position on the foot without the use of adhesive tape or the like.

The operation of this invention will be clearly comprehended from a consideration of the foregoing description of the mechanical details thereof, taken in connection with the drawing and the above recited objects. It will be obvious that all said objects are amply achieved by this invention.

Further description would appear to be unnecessary.

It is understood that minor variation from the form of the invention disclosed herein may be made without departure from the spirit and scope of the invention, and that the specification and drawing are to be considered as merely illustrative rather than limiting.

I claim:

A callus eradicator comprising a continuous elastic band shaped substantially to fit the forward portion of a foot, a portion of said band being impregnated with a moisture impervious material to cover at least the ball of the foot.
