> 3) Replace your shoes when mileage equals 500 - your loaded weight (bodyweight + pack). Do not risk your foot health for a hundred bucks.
Converting units to metric (km and kg), Replace your shoes when they are worn 800-3.5*(loaded weight)

I don't necessarily agree with the rule of thumb, I was just converting it into units I could understand and thought I would share it with the community. They do line up approximately with injury-avoidance running shoe wisdom (replace every 400 to 600 km), so it seems plausible. I think it would depend a lot on the individual (i.e. I hike in trail running shoes, so I should replace more frequently than someone who uses heavier duty boots - might just want to replace insoles occasionally?)
