For the last 9+ years I've run at least 2000 miles per year (and have broken 3000). This year I was coming off a painful achilles injury, so I will be just under 1600. I go through about 6 pair of running shoes per year (anywhere from 300-600 miles per pair). I was a big New Balance fan for many years but switched to Nike Flex, which are more of a "minimalist" shoe. I like them and think they've helped w/ the achilles problem I was having...
