Very cool but I'm no athlete. I just want something that's good for being on my feet all day. What are walking shoes? What are training shoes? What are sneakers? Is it ok if I buy Tennis shoes? I know I probably don't want running or XC shoes but are basketball or hiking shoes ok? It would be nice if all these shoes weren't sequestered away into vague categories so I could see everything at once.
