Of course it does. That doesn't mean it "wears down" the body in a meaningful sense. The body heals. Bones get stronger with use. So do muscles. Even connective tissue gets stronger with use. Cartilage might not (I'm not sure) but heals. It doesn't just grind down from use, or professional runners would all have severe arthritis at 25. Sedentary people still get arthritis.

I'm not sure you're a representative sample. It's not normal to be unable to walk in regular shoes unless you're elderly.
