I did think through many of those possibilities – but came up with nothing. I was on the mill so no change in surface – odd plant – or puddle incident. The shoes only have about 220 miles on them – but I’ll check them inside in the area for any possible disconformity issues.
Another question – the skin at the base of the nail on the big toes keeps tearing ever so slightly and bleeding lightly. How do I protect the area without the possibility of slipping band-aides? Maybe a small gauze wrapped several times?
