Abstract: An ice skate of the "plastic" type is produced by separately molding two halves of the upper portion of the skate, by subsequently introducing between the two halves a steel runner and by welding the two halves together to form a unitary plastic upper portion of the skate. The advance over prior art of "plastic" skates is in avoiding internal stress of the plastic section of the skate due to internal stress developed in known "plastic" skates due to the shrinkage of the plastic material. The molds for producing the two halves are considerably less expensive than those required in the production of known, single-piece plastic skates. One of the "halves" of the plastic upper portion comprises at least one generally complete supporting column section provided with a flange for securing the skate to a skating boot.
