If you walk 1000 miles, your feet will hurt. No doubt about it. My shoes have over 1000 trail miles on them and they were so good to me I bought a new pair. The day in and day out grinding of these shoes and the fact that they haven't fell off my feet is impressive for a pair of shoes that most people say last only 400-500 miles at most. My Pearl Izumi SyncroFuel Trail 2 shoes have seen better days and it's now time to turn them into the rubber gods. the pictures show what a beating you put your gear through. For a lightweight trail running shoe that has climbed 6000' peaks and slogged through mud for days on end, I'm happy. Here's to another 1000 miles and more sore feet and mud.
