Concrete finishers' knee skis provide a support for a cement finisher to move across wet cement, either kneeling or standing on the skis. Each ski is formed of a elongated sheet stainless steel body with upturned ends and with side walls, both bent with a curvature radius of about 1/2 inch. In one upturned end is a stirrup cage having a top opening to receive the shoe toe or a worker in a kneeling position, and a second side opening to receive the toe of the worker in a standing position. The ski is thus pulled and pushed only by the shoe toe, and may be moved forward, backward, or sideways without indenting or otherwise damaging the surface of the finished cement.
