Just bought my second pair.  I've worn NB's cheaper walking shoes for many years, the kind you buy at the mall.  Always comfortable with no break-in.  I found these online while looking for the model I had worn for years.  NB periodically changes its models which drives me crazy.  Anyway I tried a pair of these because they got good reviews and I do role my heels a little.  I wasn't expecting the difference these made.  At 50 I thought a little knee and hip pain was par for the course.  These sneakers said no.  Within a few days I could feel the difference.  I still have some of my old sneakers kicking around for yard work and such.  If I wear these for just a few hours I feel it in my knees.  Well now I have a pair of 927 for yard work.  Also, these claim better slip resistance which I can confirm.

NB - please don't change these.  Just fire your design and marketing staff and keep making these.  Thank you
