> Whenever a thread comes up about the durability of this or that model or make of running shoe you discover that people have very different experiences with the same shoe. For what it's worth (not much) I got 800+ miles out of a pair of Brooks Cascadias.
Yes exactly. The only shoes I've taken beyond 500 miles were a pair of Hoka Challengers, which other people have found to not be very durable!
I think it depends on what they're used for. My longer serving shoes may have been used over extended dry periods on good terrain, whilst those that got trashed quicker were possibly taken over less forgiving and muddy terrain.
Also as I get older, slower and tread more carefully I find shoes last longer
As an aside, I had a pair of Brooks Cascadias for years... don't know how many miles they did but they just wouldn't die. I didn't actually like running in them, found them too stiff, so I eventually popped them in the charity bin.
