This shoe was recommended for people with plantar fasciitis by a health site.  These shoes feel amazing with my Superfeet Blue insoles.  This is the first pair of tennis shoes in the past several years that I can wear all day without getting sore.  I have purchased NB 600 series in the past and they always run small.  I ordered them big and they were too big.  I had to exchange for my casual shoe size and it as an exact fit!  I am sure I will wear out these shoes within a year and expect to order another pair in the future.  Thank you NB for a great shoe.
