They do – just not a lot, depending on your surroundings.
Your body can automatically constrict blood (and thus heat-) circulation to your extremities to limit wasting precious body heat. Keeping your brain and heart alive is far more important than keeping your toes alive, after all.

Because not enough blood is being pumped into them, plus their shape and position makes them easily lose heat.
