ABSTRACT:
A shoe construction which is adjustable in girth to accommodate different foot widths includes a shoe upper having side edge margins attached non-elastically to the edges of the shoe sole. At least one side margin of the sole is deformable to permit a vertical component of motion of the corresponding shoe upper side margin with respect to a foot support surface inside the shoe so as to adjust the shoe girth with respect to a foot support surface inside the shoe to accommodate the width of the foot inserted into the shoe. Various shoe constructions for achieving such girth adjustment automatically and manually are disclosed.
