Abstract
An adjustment system for a shoe which permits independent adjustment of the width, footform and cushioning either between the lateral and medial sides of the shoe, or at different points along the longitudinal direction of the shoe. The present invention provides for the adjustment of the dimensions of a shoe in a plurality of discrete locations as between a nominal central point in the forefoot area of the sole and the medial and/or lateral aspects thereof. Adjustment would entail adjusting the width or girth in an associated area and the overall shape of the outline of the sole of a shoe. This is accomplished by providing a material variance in the midsole and various hardware configurations for adjusting the width of the midsole.
