BF Running (Saturday)

Ran 0.4 miles barefoot.  An unillustrious beginning to the "Run Barefoot One Mile Per Week" project!  It was quite cold (low 50's, I think) and early in the morning, and two toes on my left foot went a little numb.  Whether this was from the cold or from some kind of neuralgia (I originally typed "neurasthenia" - suppose it could be that too) I can't say.  I also got a little pain right in the middle of my right foot.  This felt like Morton's Toe acting up, but I now think I may have stepped on something that was sharp enough to break the skin.
