Invisible protection against external aggressions

We do not always realize it, but our feet live on the front line of daily life.
They absorb the pressure of long hours, the friction of socks and shoes, the dust of every surface we walk across, and even the drying effects of air conditioning. From morning until night, they carry the weight of everything we do.
Redness.
Irritation.
A feeling of tightness.
Sometimes roughness, sometimes tiny cracks, sometimes that uncomfortable burning sensation that makes you want to rub your feet together under the sheets.
Yet most of us simply rinse them off, dry them, and move on.
Many people are discovering that a simple dab of Vicks in the evening can act as a powerful protective ritual for tired, overworked feet.
