I have arthritis in my midfeet and was interested in trying these out because of the way the make you use each toe individually. They are very comfortable, but they do take some getting used to. I have only worn mine as "house shoes" - around the home and garden. I do like them and they are good for getting your feet and toes mobile, but they don't seem to last very long. I bought mine in October. As of mid December, I have worn them a few hours a day maybe 4-5 days a week. I have washed them twice - both times in cold water and left to air dry. First time, they were fine, but the second time the sole has started to peel away from the top of the shoe. Not impressed as they are not an cheap shoe to buy. I was thinking of getting a second pair, but I am a bit put off by their lack of durability. You do need to wash them as they can get pretty smelly, even with the special deodorizing material. But it is disappointing to find them falling apart after 2½ months and 2 washes.
