These shoes are absolutely perfect!  They are extremely light weight - yet provide excellent support for hard surfaces.  I usually walk 5-10 miles a day, frequently on sidewalks and asphalt, and these shoes are the perfect pair for that activity.  Surprisingly, they did not require any break in period (which I normally find necessary with new shoes).  The first time out, I hated to end the walk as these felt so good.  I was a little nervous as the toe box seemed a little roomier than I'm used to (even with Asics), but it only enhanced the feel when walking.  I recommend these without reserve.
