ABSTRACT:
An outer shell construction particularly suited for a ski boot and method for forming same is provided. The outer shell construction is formed by the steps of injection molding an outer shell, and securing a collapsible core to the inside of the boot to define a cavity between the boot and the collapsible core. The collapsible core includes a conduit therethrough. The outer shell construction is completed by introducing a cellular polymer in viscous form through the conduit into the space and curing same.
