Abstract

A footwear bipolar last, is adapted to self extending and to stress the shoe or the like being worked thereon. The coupling (333) provided between the two polar bodies (2, 2') of the shoe last (2, 333, 2') comprises at least a longitudinal guide (3) substantially axial which adjusts the shifting between the two components (2, 2') in a range comprised between 5 mm and 30 mm, keeping them in line and in the same direction and comprising a spring (30) which permanently and intensely forces the two polar bodies (2, 2') in the most mutually allowable far apart position.
