An ice skate runner for use in a skate holder has an elongated metal body with a solid central portion and a pair of elongated cut-outs, one on either side of the central portion extending towards the end of the runner. The portion of the cut-out adjacent the central portion is wide and the cut-out tapers downwardly in width towards the end of the runner. The plastic holder for the runner is molded around the latter so that the plastic flows through the cut-outs. The solid central portion of the runner locks the plastic at that area and forces the plastic on cooling to shrink from both ends of the runner towards the center, relieving stress in the combination. Spacer pins are inserted in the mold adjacent the ends of the runners during the molding process and then removed thereafter to allow shrinkage space between the ends of the holder and the ends of the runner.

A combined ice skate runner and plastic holder therefor, said holder comprising a heel column and a sole column, each column including a plate on the upper end thereof for connecting the holder to a skate boot, and a bridge member interconnecting said columns; said runner comprising a planar, elongated metal body having a lower portion including a hardened, ice-engaging edge and an upper portion embedded in the plastic holder, said runner having a wide central web intermediate the upper and lower edges and at least one elongated opening on either side of said web; each said opening being completely surrounded by portions of said metal body, said opening tapering downwardly in width from the central web towards the ends of the runner such that, during construction, the material of the plastic holder flows through said openings and shrinks toward the central web of the runner.
