There really is a difference between a running shoe and a walking shoe!  I was wearing runners and experiencing some discomfort on the ball of my foot when walking, but these have more cushion there and so far so good!  I haven't had them long enough to comment on longevity of the shoe.  I've worn them walking outside and on the treadmill.  The mesh breathes well so no heat buildup in the shoe.  I wish they came in black like the men's so I didn't have to fret over them getting dirty when walking outside:)
