I was out walking the other day and started getting a sore heel a mile away from home. By the time I got home it had blistered and popped. There was a hole in the heel of my sock which I think was the problem. Anyway, the question is what is the best way to get this thing to heal quickly? Leave it open as much as possible? Cover it and use some polysporin on it? I'd like to get back to my walking routine ASAP. The dog likes to practically run the whole way so I can't dilly-dally.
