A pedal connection arrangement includes a pedal having a spherical portion
with an outer spherical surface. The pedal connection arrangement also
includes a bicycle shoe that has a pedal gripping cavity that directly
engages at least portions of the outer spherical surface of the pedal
when the shoe is engaged with the pedal. The shoe is configured so that
the pedal gripping cavity securely grips outer spherical surface of the
pedal, yet remains free to swivel in various directions about the
spherical portion of the pedal when the shoe is engaged with the pedal.
The various directions include directions other than about the pedal
longitudinal axis, thereby giving more flexibility for movement of the
rider's foot while maintaining positive contact between the shoe and the
pedal.
