This is my favorite sandal ever. I buy a pair every year. I just use them till they were out which usually takes about a year. I got an awesome deal on these at Christmas time would definitely recommend them for anybody who has problems with their back or feet. The only thing to really know about these is there not good sandals to get wet. It can take a very long time for them to dry depending on the climate you live in and the steps you take to dry them. But it's really better to just not get them wet in the first place use flip-flops as Water Sandals.
