Toe hurt throughout the run as it has for over a week. This time I took off my shoe to find a bloody sock. Taking the bandaid off I saw that a pretty thick layer of skin about the size of a dime was flapping in the breeze with raw skin underneath. Ouch. I've had this before (although not this bad). It eventually goes away, but I'm not sure how exactly. I think my shoes are too narrow. Even the Mizunos with the wide toe box are a problem. Maybe I need a wide?
