Sore Ankle

Yesterday I woke up with a sore ankle. I'm not exactly sure why it's sore, as I didn't run the day before and it felt fine. It might be the shoes I've been wearing a lot lately, which offer very little support. If I can, I'm planning on running 3 today, 2 tomorrow, rest Wednesday (my running buddy, Dave, is out of town), 3 Thursday, 3 Saturday, 3 Sunday.
