Abstract
In an extensible shoe shaper, the toe and heel are connected by means of a kinematic hinge element, formed of a plastic material strip of varying thickness applied by pressure, the configuration of which can be varied--in order to vary the extension of the shaper--by means of a screw handwheel, slidably fixed to the toe and acting on said kinematic element.
