ABSTRACT:
A shoe construction which is adjustable in girth to accommodate different foot widths includes a show upper having side edge margins attached to the edges of the shoe sole. The sole is deformable to permit a vertical component of motion of at least one shoe upper side edge margin relative to the foot support surface in the shoe so as to adjust the shoe girth sufficiently to accommodate the width of the foot inserted into the shoe. Various means for achieving such girth adjustment automatically and manually are also disclosed.
