ABSTRACT:
The present invention is a device used in conjunction with a heat source to locally enlarge an area of a ski boot. The devices comprise a spreader and an extender. The spreader mechanically forces apart a pair of curved elements or "shoes" that apply pressure to both the medial and lateral side of a boot. The shoes on the spreader may be replaced or pivoted in order to use the spreader to enlarge the upper portion of the boot. The extender has a slot, a toe shoe, and a heel shoe that conform to the corresponding regions of the boot. The spreader fits within and matingly engages the slot of the extender and applies a force from within the slot, thus causing the extender to transmit this force to the toe and heel region. In all of the above instances the area of desired enlargement is heated prior to application of force to remove the elasticity of the outer shell temporarily so that the stretching is permanent.
