I am 68 years old and walk 5 miles daily, mostly on dirt.  I have tried many different hiking/walking shoes, but nothing compares with the Moab Ventilator.  I have wide feet and some of the other shoes that advertise a "wide" version are not close and are not "wide".  The Moab Ventilators need very little "break in", are comfortable from the first time you wear them and are very durable. I also have a pair of the mid (as opposed to the low cut) and they are equally as good.
