Answer 1

If you look at your foot, you can see more veins near the surface of the skin than you would if you look at your lower leg because there is far less fat or muscle. With all those blood vessels near the surface of the skin to help transfer heat/cool between the blood and skin surface, feet are great temperature regulators.
