To go along with Carleton's cleat tracing tip. Practice first. The last time anyobody probably traced something was their handprint in kindergarten. We probably weren't too good at it then, and we've certainly not practiced it since. A millimeter here and there can really throw off the rotation of a cleat. If your cleat sits flush with the shoe, then a paint pen will take care of the outline for you. If not (maybe the interface is undercut), then try with a pencil first.
