There was another story for Walter. Shoes. If Lunarians wear them, they tend to be the soft kind, like moccasins, or socks. Reason: in a crowded urban environment of perfectly smooth floors and carpets and a majority of barefoot people, hard shoes are anti-social. You could break someone else's toes. Once I had my feet jammed into the smelly things I had to search for the buttonhook. Buttons, on shoes! It was outrageous. How had people ever tolerated such things? To add insult to inutility, the damn things had cost me a fortune.
