ABSTRACT:
A footwear last usable in the mass production of footwear comprises a solid body having a top, bottom, toe and heel portion with a smooth contoured sole surface connecting the toe and heel portion including an inner longitudinal arch formed on the sole surface and on an inner side of the last, an outer longitudinal arch formed on the sole surface on an outer side of the last. A first transverse arch formed proximate the toe portion. A second transverse arch formed forward of the heel portion. The smooth upper surface transitions to the smooth sole surface in a continuous curve free from a sharply angled last bottom featherline and the contoured sole surface defines three separate and distinct contact areas. The sole surface projects cross-sections of varying percentages with respect to the total cross-sectional area onto a base plane at different heights above the base plane in accordance with the unique contours of the sole surface. Invention footwear made on the last of the invention reflects unique projected cross-sections of the last onto a base or grand plane when the footwear is worn.
