Abstract
A bicycle shoe sole includes a bottom portion having a number of projections extended downwardly from an outer peripheral portion and having a middle portion having no projections, and having a stud extended downwardly from the middle portion. A coupling member is integrally formed on the stud, without fasteners, by such as molding or mold injection processes, to allow the coupling member to be solidly disposed and attached on the bicycle shoe sole, and to prevent the coupling member from being disengaged from the bicycle shoe sole. The coupling member includes a front protrusion and a rear protrusion for coupling the shoe sole to foot pedals of bicycles.
