Several things about these sandals could be improved: 1. the lace-up part is purely decorative and unnecessary. 2. one has to slide one's foot far into the toe area in order to get the back up over the heel and that is a struggle. 3. they are hot--having an opening on the top toe area would help, I'm tempted to cut one. 4. Small debris enter the sides and since they're hard to take off and put on, becomes annoying. I wouldn't buy them again.
