A last for shoe production. In that last there is defined a metartasal line being the line corresponding to that line of the foot sole connecting the joints which separate the metartasus from the phalanges. The last is characterized by at least one bulge at the metatarsal line region so designed that when the last is rested on a horizontal surface the toe portion remains clear of that surface while when the last is tilted by lifting the heel portion by the height of the designated heel, the toe portion touches the surface. It is further characterized by the fact that a cord extending between the two end points of the metartasal line is normal to the median vertical plane of the last.
