If I could give 10 stars I would!  Wore these out of the box to Disneyland and walked  9.5 miles.  No pain, no breaking in, no blisters.  Loved them so much just bought a second pair in Navy.  You will not be disappointed and your feet will love you!  Those in tennis shoes were complaining at the end of the night - not me. Also went on a 2 mile hike in the hills wearing them on saturday ( wasn't planned) and they got real dirty but cleaned up nicely.  Ultra comfortable.
