CA 2183905

In a new method of molding a shoe heel a molding material is injected into a shoe heel mold while one or more chamber forming rods or tubes protrude into the heel portion, the rods or tubes being removed usually just prior to the final setting of the molding material while this is still relatively easy to do. The open ends of the chambers that are formed are closed by suitably shaped plugs. The rods or tubes thus form a corresponding number of enclosed hollow chambers which provides a different degree of resilience to heel strike forces at the location of the chambers. The invention also includes apparatus for making such heels, and the heels when so made. The molded body may comprise a sole with an integral heel portion.
