I ran through two pairs of New Balance in less than a year. The last pair started tearing up at the inside of the heel, exposing the rather annoying hard plastic.
I won't buy this brand any more. I found it not fit for constant, daily use. It might fare well for occasional workouts or if you have an office job, though.
I stick with boots or a mid-range pair of Nike air shoes (if I can find a pair that's not horribly obnoxious looking. I wouldn't be caught dead in those ugly Nike shox things.)
