I have mixed feelings about the New Balance 759 shoes, hence the 3-star review.  I should note that this is the second paid that I have purchased; I wore my first pair for over a year.  On the plus side, they are quite comfortable.  I do a lot of walking, and because the balls of my feet are susceptible to pain, I have typically had to use inserts with my walking shoes to provide a sufficient cushion.  I have not had to use inserts with the 759, which speaks well to their cushioning.  On the minus side, they do not seem quite as well-made as walking shoes that I have purchased from New Balance in the past, such as the 645.  The sole seems to wear out more readily.  After a half-year of wear, the outsole lining the perimeter of the shoe completely separated from the midsole, and I was able to squeeze out additional use only by re-gluing the separated soles on my own.  Hopefully New Balance can improve its manufacturing process to address problems of this nature.  Because of their cushioning and their fit with my narrow feet, I still prefer these to other walking shoes, despite the problem I have highlighted.
