ABSTRACT:
An insole for footwear has odor masking or malodor counteractant material dissolved, trapped or encapsulated in a somewhat resilient resin coating through which it will progressively migrate or bleed under application of foot loads, foot perspiration and elevated foot temperatures to the surface of the coating to be released into the footwear to mask or counteract foot odors. The material may take the form of volatile fragrances or perfumes or materials which interact with bacteria causing foot odors, such as chlorophyll, esters and salts of certain fatty acids. Release or bleeding of the material is relatively dormant until activated by foot loads, foot perspiration or elevated temperatures. Initial foot loads, foot perspiration and elevated temperatures release the material closest to the surface of the coating in which the material is trapped and then migration proceeds slowly and progressively under repeated foot loads to provide a prolonged release time. The material which does not migrate to the surface under initial foot loads remains trapped and available for migration and release under subsequent foot loads.
