The shoe is connected and disconnected to the pedal by a simple edgewise movement, with the connection being arranged to maintain the shoe in driving relation with the pedal when pedaling force is applied. In an alternative construction, the male connecting lugs are formed on the pedal while the female receivers are formed on the shoe.Field of SearchWith toe or shoe clips | |
