A skate assembly that includes a rigid runner plate mounted perpendicularly to the underside of a boot. The runner includes one or more cutouts where wheel or roller assemblies are rotatably mounted. The roller assemblies lowermost tangential edge is aligned with the bottom edge of the runner. The roller members for the respective roller assemblies include serrations on their periphery. The result being to lower the overall friction of the edge by reducing the effective contact area of the edge with the skating surface by introducing the cut-outs with roller members providing a support point in the middle of the cut-out. |
