Does anybody get times when their soles feel like they're on fire when they're running? What's that about?! Often not both of them, and often not all the time during the same run. I'm not doing anything differently... Laces aren't too tight, I don't think. Do people wear cooler socks in the summer?
I'd like to think that "I'm on fire baby" with my running, but even I can't delude myself that much!
