ABSTRACT:
The invention relates to a heel and sole assembly for an adjustable arch shoe. The assembly comprises a fixed nondeformable support element forming a heel portion and a sole portion, a pivoting element which covers a rear portion of the sole and heel portions and which is articulated upon the sole through an axis which is perpendicular to the length of the shoe so as to pivot between a lowered position and one or more elevated positions, a locking element to lock the pivoting element in any one of its positions and a prestressed spring arranged between the fixed support element and the pivoting element to force the latter upwardly to a desired elevated position. Such an assembly makes it possible to instantly change the heel height of the shoe without removal of the shoe from the wearer's foot.
