ABSTRACT:
An apparatus for selectively stretching portions of boots and other footwear. There is a stretching assembly having first and second elongate arm members joined at a pivot point, so that forward jaw portions thereof are forced together in response to rearward extension sections being forced apart. A matched set of domed and cupped-shaped members stretches the material of the boot. The spring action is provided by interchangeable hydraulic cylinder and hand-operated screw-drive mechanisms.
