Abstract: A method and kit for preparing a last for footwear. The method includes applying an elastomeric liner having a smooth continuous inner surface on a foot to be molded inner surface and optionally spacers for pads or orthotics as needed, applying a pliable, hardenable sock structure over the liner in close conformity with the foot, liner and spacers, activating the hardening agent of the sock structure, removing the sock structure now having a mold cavity in the shape of the foot with the liner forming the inner surface of the mold cavity and with the mold cavity including the spacer geometries after the sock structure has hardened, pouring a settable last forming compound into the cavity of the sock structure and removing the sock structure with the liner after the settable last forming compound has cured, thereby yielding a positive impression of the foot that is directly usable as a last. A kit according to the present invention includes a combination of elements and materials used to carry out the process.
