ABSTRACT:
A V-shaped shell comprising a replaceable tip for a mold apparatus utilizable for squeezing a shoe upper against a female mold. The V-shaped shell comprises generally planar members meeting at a curvilinear apex, each planar member having a raised periphery which tapers inwardly towards the surface of the planar member, to define a pre-arranged volume for the tapered distribution of stiffening resin applied between the inner liner and outer layer of a shoe upper.
