I am an underpronater with high arches and have been wearing out New Balance shoes in 3 months and suffering from aching feet (I walk 4 miles, 5 days/week).  I am going on 4 months with these and they are just starting to wear down.  My feet no longer ache.  Love them.  I had to buy 1/2 size larger and a Medium as opposed to the Wide I was wearing in New Balance.
