I got these in the tiffany blue color and they are so cute.  Perfect color for spring.  I hadn't worn new balance sneakers in a while and was concerned they would be too wide because they are usually known for that but they fit great.  I wear these mostly for walking too and from school which is about 2.5 miles each way and find that they are comfortable and provide just enough traction.  I haven't taken a run in them yet but imagine they would be nice for running.

They do have a slightly firmer sole - not as bending as most shoes which gives them great stability but they are still super light.  However, if you're looking for a really soft and bending sole you won't like these.
