I've heard anywhere from 300 to 500 miles and/or a certain number of months. Do you have a rule of thumb or just change them when you feel they're worn out?
I run in Brooks Glycerin 15s and have about 270 miles on them right now. I normally change out at 300 miles. But I've lost a lot of weight and these shoes still feel fine.
