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!
I run about 1000km/620miles usually. Altough my brooks (adrenaline) tend to be a bit less, around 900km/560miles. The rubber on the sole is usally completely gone in some spots. Adidas shoes, with the continental rubber on the soles, tend to last a bit longer. I'm about the same weight as the op.
