I needed a new pair of walking shoes for my treadmill and chose this one.  The only "bad" thing, if you want to call it that, is that this shoe runs a little bit small.  I'm a women's 8.5 (regular) in all shoes, even other ASICS tennis shoes, but I wound up needing a size 9 in this particular shoe.  However - the exchange process was SUPER easy (they even sent me the replacement pair before I had returned the smaller size).  Can't ask for better than that!

As for the shoe itself, now that I have the correct size they're a dream to wear.  Very comfortable and I've already pounded out several thousands of steps on the treadmill without any kind of blisters, discomfort or needing to "break them in".  They were comfortable from the get go.
