The shoe sole sanitizer (100) provides a UV radiation emitting system that kills microbial pathogens deposited on shoe sole surfaces. The system includes a housing (111) containing at least one UV radiation source (134). Bottom and side portions of the housing (111) are opaque to provide a UV shield while directing the UV upward towards a top housing portion. The top housing portion has a plurality of holes (104a 104b) forming an approximate shape of two shoe sole bottoms. The holes (104a 104b) allow the UV radiation to escape the housing and target sole surfaces disposed on and over the exterior of the housing top. Each shoe sole approximation area has a pivotal tang (102) that extends therefrom. Shutters (119) attached internally to the tangs (102) extend or limit UV exposure from the top surface depending on the size of the sole disposed on top. The system is powered by standard AC electrical power or battery sources.
