Getting Cold Feet in the MVO2

OK this is the first time my feet were the point of failure on the MVO2.

Laugh it up you Minnesotan Eskimos. But I've got prissy feet that can't handle 45 degrees F.
I went bare foot and the grass was damp so it felt colder. And after 20 sets I couldn't feel my toes anymore.

I stopped for safety's sake. Then my feet felt worse. It hurt the most just walking the 24kg back into the house.
