Abstract
A kit for use in preparing a last, i.e., an anatomical model of the human foot for use in the contruction of custom footwear, as well as a method of preparing lasts, the lasts prepared by such a method, and the custom footwear constructed by the use of such lasts. The kit includes a hardenable, shell-forming fabric that can be conformed to the shape of the foot, hardened in its conformed shape, and removed from the foot in a manner that does not substantially destroy its conformed shape. The resultant shell, being sufficiently smooth and being of substantially the same size and shape as the foot, can be used directly as a positive model of the foot.
