ABSTRACT:
An adjustable height shoe for leg lengthening procedures to correct for leg length discrepancy has a removable outer sole which is coupled to a midsole of a shoe upper with a number of unequal, graduated thickness interlocking connecting filler soles interposed therebetween. A removable heel pad provides a heel lift of one-half of the thickness of the thinnest filler sole. Gradual reduction in the vertical height of the stack of filler soles and the outer sole in conjunction with inclusion or exclusion of the heel pad is correlated to the increase in leg length of the wearer. Opposing, abutting faces of filler soles or of filler soles with the outer sole and midsole are interlocked by correspondingly sized, configured height projections and recesses such as circular pegs and circular holes for the abutting members. Straps passing through aligned vertical slots within the outer sole and the midsole maintain the filler soles as part of a stacked assembly.
