Abstract: A light weight, strong die cast sole plate for a roller skate. The sole plate includes an action screw boss and a front truck ball socket in a sole plate toe portion. A central rib extends longitudinally between the action screw boss and the front ball socket. Diagonally disposed ribs extend from one side of the action screw boss to an opposite side of the front ball socket and cross the longitudinal rib. This structure permits production of a strong yet low cost sole plate.
