Abstract: Methods for providing footwear configured to treat leg length discrepancy include manufacturing a plurality of footwear members. Each footwear member has a sole thickness, with sole thicknesses of the plurality of footwear members spanning a predetermined range of thicknesses. A corrective pair of footwear may be formed by selecting a left member having a first sole thickness and a right member having a second sole thickness, wherein the difference between the first and second sole thicknesses corresponds to an amount of leg length discrepancy to be corrected.
