Abstract: The present invention relates to a shoe for a bicycle wherein a shoe can be easily coupled to a bicycle pedal and can be conveniently separated from the pedal even without the installation of a toe clip for enabling a shoe to be inserted into a bicycle pedal. The shoe for a bicycle is formed in such a way that the front portion of a sole provided beneath a main body of a shoe is high and the back portion gradually becomes lower than the front portion, and a coupling groove is formed beneath the front portion of the sole so as to allow a pedal to be coupled or separated. Even if a toe clip for enabling a shoe to be inserted into a bicycle pedal is not installed, a shoe can be easily coupled to a bicycle pedal and can be conveniently separated from the pedal.
