The mechanical structure includes a nozzle-guide template that is configured to an outline that, together with other mechanical structures, matches the outline of the insole between the toe and the ball region of the smallest upper assembly of the style to be lasted: The nozzle-guide template has a guide surface and is shiftable to accommodate, for example, right footwear upper assemblies and left footwear upper assemblies of the style to be lasted: The nozzle-guide template is composed of a plurality of segments at the toe region thereof to permit angular adjustment of one segment relative to the other to match the shape of the insole for footwear sizes larger than the smallest footwear upper assembly.
