Abstract
Abstract The impregnation of a foam rubber, or similar polymeric material, insole with an effective antibacterial and antifungal agent along with a deodorant provides a simple, clean source of active ingredients for curative and prophylactic treatment of infections of the feet and reduces odors during the course of the treatment. The agent of choice in such a product must be stable to the conditions of use and be sufficiently non-volatile to be retained in the insole over a period of days or weeks.
