I have never gotten 400 miles out of a shoe. I'm 190lb runner and have gotten as low as around 200 miles and looking back through my Garmin retired shoes managed 370 once. At any rate, shout out to these Brooks Ghost 13's :)
Normally something (knees) let me know it's time to switch. These I retired due to running out of sole! At any rate, 95 activities, and 444 miles is a record for me!
Ya, I assume weight has a big impact, but obviously how much you scuff/how you land etc.. Just crazy how even these wore without causing any running issues. Wouldn't think my running changed much just out of the blue.
