I'll chime in.

This idea that heavy people shouldn't run barefoot is complete nonsense.

It's like saying "We're fine if you jam a ton of force into your JOINTS… but not if you try to use your muscles, ligaments and tendons!"

Granted, with extra weight comes extra force, but that just means being extra careful… by not doing too much too soon. Give your body time to recover and build up slowly. Put in some extra time walking. If you're not having a problem, then ignore all the people who say, "You'll have problems!"
