That sitting on your ass for 7 years and working makes you fat and lazy. It also makes your feet un-used to walking a lot. Yesterday we walked around the Henry Ford Museum for a couple of hours and my feet were killing me. Then today we walked around downtown Detroit for a few miles and same problem. I don’t think shoes have as much to do with being able to walk a lot so much as walking around a lot has a lot to do with being able to walk a lot. Or something.
