Review of the patent literature reveals two basic types of wedges described to compensate for angular deformity in the leg.
Over the last 30 years one wedge, the Medial Longitudinal Arch Wedge, became popular. Ninety Eight percent all prescription and over the counter orthotics/arch supports used only the MLA type of wedge. My first 12 years of research tested my method of quantifying the MLA wedge. Later I tested the Metatarsal wedge used independly with out the MLA. Over the last 15 years I have studied and tested use of both the MLA and the Metatarsal wedges.
Although both wedges will control foot function and have value in certain shoe types and physical activities. The combination of both MLA and Metatarsal wedges, control the foot optimally, by maintaining the wedge throughout the entire weight bearing gait cycle.
When both MLA and Metatarsal wedges are present in the orthotics, the foot control is significantly improved , from attempts to control foot function with either wedge use individually. Additionally a more natural and comfortable restoration of function can be accomplished.
