ABSTRACT:
A bicycling shoe has a ferromagnetic backing plate positionably connected to its sole. A nonmagnetic support plate has a plurality of through holes, and is fixed to the backing plate. NdFeB magnets of alternating polarity are attached by epoxy to the sidewalls of the through holes and make magnetic contact with the backing plate. A similar backing plate, support plate and alternating polarity magnet assembly is fixed to a bicycle pedal. A post extends from the pedal to position the shoe laterally. When the shoe is in a pedaling position, the polarity of the pedal magnets is opposite to the polarity of the shoe magnets, and the shoe is gripped to the pedal to permit transmission of power on the up stroke. To disengage, the shoe is rotated about the post, until like magnets are brought into opposition and the shoe is ejected from its position on the pedal.
