The glass ampoule or other sealed container will contain a suihcient dose'of any of those known effective puritives for infections `of the feet which may be applied in a liquid form. In particular an oily substance, preferably more or less volatile, may be used. Such an oily substance may be a light petroleum oil, for instance any hydrocarbon fraction within the range of petro- Y leum ether and kerosene. such as gasoline or kerosene. When the interior -of the shoe is thoroughly saturated therewith, such a substance serves to effectively discourage the infectious organisms which are present. When used with leather shoes it has the additional advan tage of nourishing and'preserving the leather.

A particularly effective disinfectant composition consists of an emulsion of a light petroleumv oil with an aqueous solution of a disinfectant substance. The light petroleum oil is preferably the so-called soluble oil, which is a highly purified, water white oil which can be easily beaten into an extremely stable emulsion with water or aqueous solutions. 'A suitable disinfecting agent for the water phase is a dilute solution of chlorine or other oxidizing agent in water. Small amounts of suitable emulsifying agents may be present. If desired, various essential oils, such as the various terpenes, may be included in the mixture to give a pleasant odor to both the disinfectant composition and the treated shoes.

When theemulsion is applied to leather, the oil phase is absorbed into the leather and protects it against the hardening and cracking action of the water phase. 'Ihe disinfectant water phase serves to destroy the organisms present on the lining and at or near the inner surface of the ,leather of the shoes. Emulsions of this type are more particularly described and claimed in the application for Unitel States Letters Patent of Edward B. Beale, Serial No. 168,665, filed October 12, 1937.

The entire shoe form is intended to be made up and sold as a unit. It is preferably constructed of materials sufficiently cheap in price that it may economically be disposed of after a single application. The article is used -by breaking the tip from the ampouleso as to permit the disinfectant fluid to run out and saturate the absorbent material. The liquid is carried by capillary action to all the surfaces of the shoe form. The ampoule is of such a size that it contains the precise amount of'. liquid required to effectively saturate the entire body of absorbent material. After the ampoule is broken the form `may be immediately inserted within the shoe where the leakage from the ampoule will rapidly saturate the form and adjacent surfaces of the shoe or the shoe form may be tilted back and forth to insure the complete emptying of the ampoule and saturation of the form before the form is forced into the shoe. It is allowed to remain in place be-L tween wearing or for at least such a period of time as is necessary for a thorough saturation of. the lining of the shoe and the pores of the leather. 'Ihe form may then be withdrawn from the shoe and be discarded. A similar treatment of the shoe should take place after each wearinguntil a complete cure of the foot infection has taken p ace.

A single shape of shoe form will sufhce for various shaped shoes of the same general style since the form may be compressed into many different shapes. Only a small number of different sizes need be provided to accommodate the diverse sizes of the shoes of men, women and children, since the resilience'of. the form makes it possible for the largest size to be compressed into a much smaller shoe without a loss of effectiveness.

Certain variations in the invention disclosed will be apparent to those skilled in the art and are intended to be included within the scope-of the appended claims.
