I have them on at the time of writing, they are comfortable enough but I prefer to open the back strap to put on sandals. They don't open so I have to put them on. The strap across the bow is too short, should be about an inch longer. The first two pictures show a pair of sandals with a strap that opens and is fully adjustable. I can use this to adjust the fit front and back. Her second two sandals. There is a back strap that does not open. I have a feeling you are better off taking the adjustable strap off and just fitting the heel into the sandal.
