After being advised by a foot doctor to make Crocs my new slippers I began to add more to my 3 pair I already had.  This pair has a feminine dressy look that I had seen on a friend and liked so I ordered them.  The left fit perfectly but the right back strap was loose and I knew over time I would not appreciate that so I ordered the pair without the back strap....much better for me! As with other Crocs I assumed that back strap could be positioned forward but not so on this model--the back straps are stationary.
