And suddenly her feet began to slip in the dirt.
My hands and feet were beginning to feel the cold.
The wind rose suddenly and her foot began to feel the cold.
After awhile his feet began to pain him with every step.
My hands and feet were beginning to lose all sense of feeling.
After half an hour of this, my feet began to hurt.
His feet began to complain; they hadn't worked so hard in months.
My feet began to feel the cold of the icy water.
He set foot on the ice, began to walk across it.
An hour or so later, my foot began to really hurt.
