The invention relates to a shell part of sports shoe and a method for producing such a shell part based on joining together several components made preferably of different materials in one or more injection molding processes. The method comprises: the production of at least one three-dimensional stable shoe reinforcing part, the application of a filler material on the inner side of the shoe reinforcing part; the positioning of the shoe reinforcing part on a last; and the at least partial overmolding of the shoe reinforcing part with plastic. The method enables the simple and easily controllable production of a shell part with very high rigidity or stability at least in specific areas and at the same time also ensures the workability or adjustability of the shell part during the production and afterwards.
