I am almost 78 years old and have suffered from back pain and foot pain for years , these sandals are the first thing I put on in a morning , even if I get up in the night I slip them on to go to the bathroom , they hold my feet securely ,and as a bonus they are massaging my feet , I dont suffer swollen ankles anymore , only when traveling in a car , but as soon as I walk my ankles are back to normal , The sharp pains I used to get at night and the burning feeling isnt a worry anymore , I think I have bought just about every colour , In winter I put on a sock and wear them to keep my feet warm rather than buy a slipper , they are that comfortable , but I guess you would have to do what I did and buy a pair to feel the difference they make to your feet , and I wouldn't be with out them , the best sandal I have ever bought for comfort at my age group
