ABSTRACT:
The last for a shoe shaft includes a groove which, in cross section, has a generally T-shaped configuration, a profile band mounted in the groove and which, in cross section, also has a generally T-shaped configuration, and a plurality of springs for biasing the profile band such that a stem part thereof is biased towards the mouth of the groove where the inlet portion thereof opens onto the surface of said last, the stem part contacting the shoe shaft opposite where the sealing edges of cooperable lateral mold parts will contact the shoe shaft when molding a sole to the shoe shaft. As a result, sole material is prevented from extruding past the sealing edges of the lateral mold parts onto the upper part of the shoe shaft.
