  • Patent number: 4538480
    Abstract: To enable a cyclist to provide 360.degree. of driving force on each bicycle pedal, the cyclist's shoe is formed with a pair of lugs that mate with receivers formed on a bicycle pedal. 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.
