A cleat for being attached on a sole of a cycling shoe to be engaged with a clipless pedal is disclosed. The cleat includes a front engagement portion, a rear engagement portion and a front attachment portion. A width of the rear engagement portion is greater than a width of the front engagement portion. The front attachment portion protrudes from the bottom of the front engagement portion and includes a U-shaped body and two abutment portions. The U-shaped body has two legs and an opening between outer ends of the two legs. The opening is toward the rear engagement portion. Each of the two abutment portions inward bendingly extends from the outer end of one of the legs so as to make a width of the opening between the abutment portions less than a distance between internal sides of the two legs.
