Insole assemblies for shoe girth adjustment

A girth adjustment shoe system for providing a shoe in which the girth may be varied to better fit a foot therein, comprising a shoe having a ball region and having an upper attached to a bottom forming a shoe cavity and a means for incrementally adjusting the girth of the shoe over a range of different girths in at least the ball region of the shoe, and girth adjustment means comprising at least two interchangeable and removable insole assemblies having substantially equal thicknesses generally along their longitudinal center, each insole assembly having a different transverse surface contour and thickness along its side portions when compared to the other insole assembly, each insole assembly comprising a substantially firm member that does not compress under the weight of a wearer's foot and being dimensioned so that there is no substantial change in elevation of the foot relative to the bottom surface of the shoe regardless of the girth adjustments effected by the insole assembly, said at least two insole assemblies being available for use separately within the shoe cavity so as to provide different girths for the same shoe without deformation of the bottom.
