Love these shoes! Bought them as my first decent pair of running shoes in December as I did the C25K program. No breaking in period at all. I have since purchased a couple other pairs of running shoes so I can rotate, but I still love these! I've run two 5K races in them. I will be ordering another pair in a different color soon. They are holding up pretty well and I expect to get a few more races and tons more miles out of them (they are probably at about 120 miles right now.)
