text: I've been running in this model for about 8 months now.  My first 2 pair I got about 350 miles each and still have some life left in them.  They are the right running shoe for my body mechanics.  I've got to say the thing I like about them the most is they stay tied without having to double-knot the laces!  I regularly run 13+ miles and never have them come untied.  I ran a marathon in them and same results.  What a novel idea - running shoes with laces designed to actually remain tied!
