ABSTRACT:
A method for stretching an upper mounted on a last about the vamp of the last while the last is supported bottom-down. The last has a throat between the tops of its toe and cone portions that is bridged by the upper with the upper being spaced from the throat above the throat. The upper margin is gripped toewardly of the throat by toe pincers and heelwardly of the throat by ball pincers. The ball pincers are then moved towards the toe pincers to cause the upper above the throat to buckle into the throat and bear against the throat after which the last is raised to effect the stretching of the upper about the vamp of the last.
