ABSTRACT:
A shoe adapted for facile interchangeability into a multiplicity of styles comprising an outsole having a heel portion, with there being an intervening zone of flexure therebetween. Forward and rearward inner soles are provided on said outsole and with their adjacent end portions in overlapping relationship for relative slidability during foot movement. A retaining strap extending lengthwise of the shoe serves to optionally maintain a rear upper in operative position as well as to promote integration of the shoe components in selected mode of wear. A readily widthwise adjustable front upper or vamp is detachably mounted upon the forward portion of said outsole and replaceable by a thong detachable to the forward portion of the sole.
