Abstract (en)
The present invention is directed to a shoe cover having a generally tube-like shape with an expandable heel portion to allow the shoe cover to better conform to the foot and ankle regions of the wearer despite the simple design of the invention. The expandable heel portion is created by forming a plurality of folds across the width of the section of the material which forms the bottom portion of the shoe cover. The folds are made in the general area of the shoe cover where the heel of the wearer would be positioned. Upon donning of the shoe cover, the heel portion expands as the folds unfold, thereby changing the generally tubular shape of the shoe cover into a shape which more easily conforms to the human anatomy. <IMAGE>
