As I have been getting older, my feet have often been the most first thing to feel sore during a rough day at work.  These socks made an immediate difference and the comfort level was noticably improved over standard dress socks.  One does feel a massaging action, albeit very subtle, but it is less an immediate difference than that one feels far less tired as the day wears on.  The only down side is the socks are not as breathable as I normally prefer, but that is to be understood as the nature of the beast.  I would also imagine the results would vary with the level of problems.  These are socks - not a substitute for physical therapy - and are meant to aid with normal day to day discomfort and not chronic conditions.  With that understood, it is a good product that delivers as promised.
