The first thing to do is to untie the laces as they have come, and then remove the laces from the shoe. Begin by lacing at the bottom, lacing in, so that the lace is above the flaps on the side. You then take one side of the lace and put it in the hole above the one it has come out on, on the same side, and lace it through. You will then pull it directly over and lace it through the second hole on the opposite side. You will repeat with the other side in the next available hole, all the way up the shoe.
