I wear these every day to work.  It's about a mile to my work.  I walk to and from there every day.  I also walk home during my lunch hour.  So very comfortable.  Never had to break them in.  Wear them outside of work too.  My only gripe is that the shoe strings come untied pretty easily so I have to tie them in a double knot.  I have been wearing them daily pretty much since I purchased them and they're still in excellent condition.  Highly recommend.  Would definitely buy them again.
