ABSTRACT:
A process for the normalized manufacture of shoes includes defining the measurements of the sole of a last, to determine the transverse contour thereof, by defining an axis transverse to the length of the sole at a position spaced one third of the length from the sole front. Four zones determined by three transverse lines equally spaced at a distance of 1/12 the length are defined forwardly of the transverse axis. The contour of the sole is determined along such lines to be flat at the line nearest to the front, to have an arch height of 1/120 the length at the following line and to have an arch height of 1/96 the length of the last line. Seven transverse lines, equally spaced at a distance 1/12 the length are defined rearwardly of the transverse axis. The contour of the sole is determined by the most forward such line to have an arch height of 1/96 the length, and to have at the remaining such lines arch heights of 1/60 the length.
