These are the most comfortable walking/gym shoes ever.  I have a narrow heel and regular sized-forefoot with high arches.  Trying to find shoes that fit all areas of my feet has been difficult over the years.  These shoes really seem to fit the bill.  They don't crowd my toes and feel nice and snug at the arch and heel.  The only minor complaint I have is that I always seem to have a bit of discomfort on the outside of the left foot when I wear them for more than several hours.  I take long walks with a friend, so can be upwards of 4 hours that I have them on at times.  Could just be the way I walk though, I have a bad habit of a heavy strike with my heels.  But I really do think these are by far the most comfortable walking shoes, and very lightweight too.

I would highly recommend these shoes!
