I have a severe overpronation problem (where the arch of the foot rolls inward/collapses too much) and have tried many different shoes trying to help relieve the pain associated with this condition.  This shoe was recommended to me by a local shoe/running expert and I am glad I tried it, as this is the first shoe I have ever tried that has made any difference at all.  While it hasn't elminated the pain completely, using this shoe, I am able to be on my feet for long periods of time without desperately needing to rest every few minutes, as was the case in other shoes.  In these shoes, I have even been able to walk all day long at places like Disneyland, Universal Studios, and the zoo without too much trouble.  I can't comment on how good these shoes are for running because I only use them for walking but I can recommend them for anyone who overpronates like me.
