I'm a mail carrier.  I walk approximately 10 miles a day.  I need good shoes.  For the last 5 years I've been wearing NB 845 and it's predecessors(843/844).  These are the new improved version of them...?  They aren't.

I need a shoe that breathes, this doesn't well.
I need a shoe that's light, this isn't as light as expected.

They aren't the worst shoe they could be, but they aren't worth anything near the almost $90 I paid for a pair.

Save yourself a few bucks and several blisters, get the New Balance 845.  They're lighter and breathe better.
