I run anywhere from 15 to 30 per week and am a large guy at 6'3" and 220lbs.  These are durable and very comfortable on the runs.  I will log about 500 miles and then rotate in a new pair.  I have been using the ProGrid for years.  Highly recommend them but they are in the stability shoe category, which means you need to know your foot type.  No issues with the shoes or the shipping.
