Abstract: A boot for Alpine skiing has a shell and sole. The heel has a cavity, including a seat for the insertion of a removable metal insert for engagement by the heel fixing unit of a standardized “Dynafit” binding. However, when the boot is prepared for use with newer, different bindings, the metal insert is replaced by a plastic insert that fits over the cavity and forms a continuous, unbroken rim on the heel of the ski boot.
