I'm sure I put over 1000 miles on my shoes. I still own them for that pair of shoes needed for dirty jobs around the house. I bought my wife a pair of shoes for her work after she wore out her other expensive Brooks shoes in just under a year. You can't beat the life and ongoing foot support from Aetrex. I only wish they had a non-slip sole so I can wear them to work. The ones stated non-slip I found did not work for me.
