Abstract: A shoe with a replaceable hygienic cartridge in the heel portion thereof, forces a chemical agent through the shoe due to the intermittent compression or pumping action while a wearer of the shoe is walking, running, or using the shoe in a similar manner. The shoe includes a chemical cartridge chamber in the heel portion of the sole, into which a flexible and resilient cartridge is removably installed. The cartridge may contain any of a number of different materials or agents, such as deodorant, anti-bacterial, fungicidal, desiccant, etc., or various combinations thereof; as desired. The upper surface of the sole within the shoe contains a series of grooves or channels therein, which communicate with the cartridge chamber by a passage therebetween. A porous insole overlays the upper surface of the sole and its channels.
