Ran four miles today, my knee hurt a little bit, but its definately improving. My new shoes are pretty nice, but I could use a little more room in front of the toes. Unfortunately, they don't make a size 13 1/2, so if I wanted more room, I'd have to move up to a 14, which is probably too big. I figure I'll try on a size 14 next time I'm at the running store, see how those fit.
