ABSTRACT:
A shoe construction for providing girthing support to the midfoot region of the foot is disclosed. The present invention provides for adjusting the perimeter of the transverse girth of a shoe in the midfoot region under varying conditions of loading. When the foot is in an unloaded condition, the dynamic girth of the present invention has no effect on the original girthing tension. Then as the foot is loaded and everted, girthing fibers or straps are forced into an undulating surface. When the everted foot becomes loaded completely, the girthing straps become mated with the undulating surface in close contiguous contact, thus pulling in the girth straps and producing maximum tension on the midfoot region. The undulating surface may be provided in the outsole so as to be positioned below the girthing straps or, alternatively, in a portion of the shoe positioned above the girthing straps. The girth structure of the present invention creates girthing tension dynamically to prevent excessive eversion when the foot loads the shoe.
