Thought I would try these out: Vibram "five fingers" barefoot running shoes. They are going to take some getting used to. I'll have to change how I run, for one thing (can't land on my heel and roll like in regular shoes: no padding; I'll have to land more midfoot). They are fun, though, and I've only worn them for a short jaunt or two until I get more used to them. And the last few days it's been too cold to be running "barefoot." It takes some practice to get them on (getting each toe in the right slot), but I'm getting the hang of that.
