Abstract: A foot cleat includes a foot cleat body with a second engaging major surface adapted for facing toward a first engaging surface of a pedal body. The foot cleat body is formed with an elongate lock slot extending in a transverse direction, and two lock holes in two opposite sides relative to the elongate lock slot and aligned in a longitudinal direction. Two friction members are disposed in two lateral portions of the foot cleat body and extend outwardly of the second major engaging surface to abut against two tread walls of the pedal body to prevent slippage of the foot cleat body relative to the pedal body. Screw fasteners are passed through the elongate lock slot and/or the lock holes in such a manner that the screw fasteners are adjustably positioned at the elongate lock slot which is adapted for registering with the screw holes in the bottom surface of the sole of a cyclist's shoe so as to be engaged selectively and threadedly in the corresponding ones of the screw holes.
