Insert the ends of the laces into the set of holes on the cleat closest to the toe. The lace goes in from the top and is pulled through from underneath. Hold the two ends against each other to make sure that you have equal length on each side, and adjust as necessary.
Lace up the cleat by crossing the laces over each other diagonally through each hole. The lace goes through the underside of each hole, out the top and then under again for the next hole. For example, the first lace on the left will go through the next highest hole on the right and so on; then it will go through the next highest hole on the left. Lace up the holes on each side before moving to the next row. Pull the laces through snugly each time, but not so tight that you have difficulty getting your foot into the cleat.
Put the cleats on your feet once you have reached the top of the holes on both shoes.
Tie the laces snugly in a bow. Use a double-knot if necessary to provide a tight, comfortable fit.
Fold the top flap of the cleat down over the laces. This will cover up the knot and also provide extra padding for your foot in case a ball hits it in the course of game play.
