I bought these shoes quite a while a go.  They are starting to look worn now, but I have worn them a lot!  They are comfortable like tennis shoes, but look more like a casual work shoe.  I used to have plantar facitis (sore heels) and have to be careful about wearing a flat shoe, or a shoe without enough cushion.  This shoe does the trick!  I can walk on them all day feel fine.  Older people may want to be careful if they have an issue with balance.  You do have to balance yourself when standing still and going down or up hills, etc.  This is what makes them a exercise shoe.  I have truly enjoyed owning these shoes.
