I've read that feet get used to winter weather as the seasons change and the weather gradually gets colder. 82℉ a few days ago, freezing by morning. Are you used to it yet?
I definitely conditioned my feet way to the freezing mark and below on some runs. I am in the south as well. It's strange weather we are having. Very warm. Lots of rain. Lots of storms. I could get used to running in that rain.
Feet still not very conditioned to the cold but as this is may be my only chance to run in snow, I had to give it a try. NWS says we got 7 inches.
