Abstract
A ski is provided with an internal support structure configured to ensure adequate strength for the ski. The internal support structure is formed to define at least one internal cavity. An outer shell surrounds the internal cavity and the internal support structure and defines the exterior of the ski. The internal support structure may be formed from opposed halves assembled to one another. The internal support structure may include a plurality of outwardly extending positioning legs formed unitarily therewith for positioning the internal support structure within an injection mold cavity. The ski may further be provided with metal edges snapped into grooves formed on portions of the bottom surface adjacent the sides.
