  • Patent number: 5361518
    Abstract: A sport shoe with an outsole cleat-type gripping element is constructed so that, even in an inclined position of the outsole, the supporting areas of the gripping element or elements have as complete a ground contact as possible, without the gripping element being damaged or destroyed by excessive lateral forces. Further, the damping property of the gripping element can be matched in a simple way to the respective requirements. In particular, in accordance with a preferred embodiment of the invention these characteristics are obtained by providing a receiving device, which has an inside thread for receiving the threaded bolt for at least one gripping element, in a holding insert that is embedded in the outsole, the receiving device being mounted so as to be both axially movable and slightly tiltable laterally without being able to rotate.
